Introduction to Oxidation States

Oxidation and reduction. Oxidation states.

[@rileypurcell2159]

OIL RIG oxidation is loss (of electrons) Reduction is gain (of electrons)

[@kenonumaku23]

beautiful

[@kovo42]

that's how i learned it.

[@nashyrg3523]

The problem is oxidation means gaining oxygen and reduction is d opposite

[@ojasapratim5319]

Mnemonics got it on Google lol

[@NomadicWanderer11]

NEVER take your videos off of youtube! Without these videos, there is no way in H_ll I could pass my college courses!

[@user-tu8ti6sr1r]

another mnemonic is OIL RIG-------------> Oxidation Is Loss (of electrons), Reduction Is Gain (of electrons)

[@yarashamali8061]

how does this one guy tutor all these subjects?

[@drakai22]

yeah, I wonder the same thing .

[@yun1666]

perhaps he knows all of these subject

[@gurujicoder]

He is from MIT

[@SaifAli-nj8fq]

With mouth and a laptop or computer

[@reginashaw8346]

Great explanation, that reduction means a reduction of CHARGE. This finally makes sense to me now - Thank you!

[@017kamakshisharma7]

People here are commenting how they were taught different pneumonics and I am sitting here wondering ..... "Why my teacher never told me about any ?"

[@ohhgeeme]

i read my college level chem book 5 times and did not understand oxidation-reduction reactions. you just made life so much easier. thank you.

[@ranjitn159]

Wooaaah. How are you doing now mam?

[@Rohit-ic5rn]

Sal's pedagogy is one of the finest

[@sarahpanic16]

I might pass my Chemistry exam because of you. Thank you so much, you're videos have taught me something in 15 minutes that my teachers would take weeks to teach. (Recommended you to my fellow chemistry buddys ;) )

[@tranquilious]

u alive ?

[@swooosh3145]

mate i love you. I hated chemistry and i think about improve my chem knowledge and rewatch this whole playlist in summer even when there is no urgent need to. Its just fun to learn.

[@tearlachbrennan5434]

also "OIL RIG" Oxidation is loss and reduction is gain (of electrons) is very easy to remember haha.

[@honeyandbees00]

Omg you're amazing!! My teacher sucks. I wish you were my teacher.

[@smithderrie]

you should come teach at my school, you're brilliant!

[@Bakugantsuvai1]

I knew that memory aid before my teacher told that to us thanks to KhanAcademy and btw I watched the redox video before watching this one but at least Sal did a good job on showing the procedure.

[@AxisMundiOnline]

I also was taught OIL RIG as a mnemonic. Oxidisation Is Loss, Reduction Is Gain.

[@SuperSmackintosh]

I wish you were my Chem teacher. I LOVE YOU

[@joelph]

another way of remembering Oxidation and Reduction is: OIL= Oxidation is loss (of electrons) RIG=Reduction is gain (of electrons)

[@user-em4rk4qo1f]

I just wondered who was this person who made this wonderful video, then saw that it was actually Khan Academy

[@sinekonata]

It's still not clear the difference between covalent and ionic. Does it start being a covalent bond when if gently pulled apart the O gives the H atoms their electrons back? Because from what I read it's not the case, when pulled apart, the O becomes 2+ and Hs become -, which makes them ions... So what exactly does it mean to "share an electron", when that's also what ionic bonds seem to do?

[@chumpz69]

I have the worse chemistry teacher, yet he hardly teaches. Thank you for khan academy

[@PKruzen]

Understood! Thanks!

[@mittomitto285]

very nice.. thanks

[@Mozzinator38]

Khana Academy is best Academy

[@sheejaaswanikumar4456]

cool

[@codyyim1]

I thought this guy only teaches math..

[@cirina3]

The coulomb's force will make them want to attract to each other or is this... ( sigh) LOOVEE? . (:3) Ionic compounds are elements in love after helping each other. ( >:)

[@DHuangful]

LEO The lion says GER

[@G0sentrick]

"Bernie Madoff'd" :P what about "Rick Rolled" !

[@dudeypierson5663]

He was referencing the wrong group of metals the whole time. He should have been saying Alkali metals not Alkaline earth metals.

[@JesustasticCats]

if there's one thing i've learned about chemistry, it is this: do not try to use logic when thinking about chemistry. just don't do it.

[@gabriellamanuel1]

redooced haha

[@TheAkshay013]

whoa whoa man ur confusing me by saying oxidation and charge. oxidation number should write like this +3. and charge like this3+.

[@ranjitn159]

Yes. Umm hope you know it by now

[@dafemartdafemart4020]

I really really hate that voice.

[@SuposedArt]

+Daniel Martinez If you put him on double speed he almost sounds like a real person talking.

[@elijahr_1998]

whenever I watch these videos I wonder why I actually pay tuition.

[@bibo170]

For the piece of crap embossed piece of paper you get at the end.

[@nightingale42]

degree. the real question is why would you go to class

[@GrantB1390]

***** If you were trying to get a job without the degree they "need", you would really want to drive home your real world accomplishments by telling them you may not have the paper that says it, but you've done this, this, and this and you'd love to be able to do that for them. I wouldn't say "KZbin" is your source of learning unless they ask it specifically, but I'd say that you were deeply interested in the field and did your own self learning course throughout multiple sources on the internet and books.

[@GrantB1390]

+David Mac yeah, I see what you're saying, but I was trying to say what I would think you would have to do should college not be in your resume. You'd have to take all the focus off of no degree and place extra emphasis on proven ability. If you have the degree, then you'd want to use it that fact too.

[@kenonumaku23]

Honestly, and to think that it comes free

[@jaredcavanagh4659]

"you do not need oxygen to oxidize something" finally someone clears this crap up! thank you!

[@Abhishek-rr5iy]

nooooooooooooooooooooooooooooooooooooo

[@Abhishek-rr5iy]

[@atypicalNerd]

Studying for tests like a boss. Binge watching at x2 speed

[@ChannelTy24]

As a Senior graduating w/ a B.S. in Biology, I am seeing these videos and being endlessly pissed off that I ever went to class.

[@smartboyharis]

Khan for Nobel Prize!!

[@ctesebius]

I really love the Bernie Madoff analogy.

[@MrEhYoung]

Oxygen is the Kobe Bryant of the periodic table. The electron hog, assuming the electrons are the basketballs.

[@eltonlucien4280]

I know this is an old thread, but lmfao.

[@huajiluhai]

You just get the perfect voice for teaching...while my teacher has the prefect voice for bed time stories...i just can't help sleeping through all of it...

[@bleach50k]

Don't you think he should teach teachers to teach...teachception... but the man is a genius. amazing guy really

[@alexusfraser7547]

I do not understand this stuff, no matter how much I study it.

[@vinh3387]

Alexus Fraser Then u dont want to...

[@jazee75]

I'm taking AP Chem right now, and so a lot of the material has to be independently learned out of a textbook. These videos help me so much in visualizing the concepts. It's kind of amazing how much it helps :)

[@fuckyeahmuse]

Bro, you the man.

[@Rohit-ic5rn]

Didn't know this quality of education was available 10 yrs ago

[@itsme0anni]

I like every single of you videos alot, they are very helpful! I watch them eventhough they are in english and I am a german student! Much more understandable than the incomprehensable chemistry lessons of my teacher. Thanks to you, I start seeing the light at the end of the tunnel again! Thank you

[@JS-zp2pc]

im the newest comment.... everyone in here is probably done with high school and is in college or something.

[@RishRam526]

In my school we learn it by remembering OIL RIG, OXIDATION IS s LOSS of electrons, and REDUCTION IS a GAIN of electrons. I dunno if this helps you but it helped me remember :)

[@caterinabiagi4742]

so when hydrogen bonds with group seven, and it has an oxidation state of +1, does it no longer have any electrons?

[@viveksr2904]

🤣

[@stinkyslinky432]

LOL, love the Bernie Madoff reference. This guy's awesome.

[@senthilpuliadi6599]

Can’t believe this is 11 years old

[@Cedef36]

Bernie Madoff must has five KZbin accounts

[@twonumbernines1097]

other than using Leo says ger, you can use OIL RIG Oxygen Is Losing Reduction Is Gaining

[@MidnightFreefall]

Instead of LEO says GER, we got taught OIL RIG: Oxidation is loss (of electrons), reduction is gain

[@robie93]

Im a college student and I plan on remembering LEO says GER for my test this week lol THANK YOU!

[@fowlgodproductions]

WWOD; What would oxygen do?

[@missqt48]

You are soo much better than my chemistry teacher, i can hear your voice all day and never fall asleep. Thank you soo much for the video :)

[@truv1217]

Thank you for helping me with my homework. My Chemistry teacher can't explain anything.

[@torontogirl3]

thanks for the explanation! your voice is totally hot too

[@Thingie5]

My chemistry teacher never explains anything, he just gives the class formulas and stuff with no context whatsoever... these videos are awesome :D

[@74dorset]

That's pretty cool of you to take it upon yourself to get this stuff by yourself, personally I use it for revision. Good on you mate.

[@tjeepert9782]

You have a wonderful way of explaining, I love it!

[@ColeMackenzie]

The charges on NaCl should be written 1+ and 1- with the sign indication whether positive or negative after the number, this way it is not to be confused with oxidation numbers which are written +1 and -1

[@HaveHeartMerch]

White Jessica White Edward Rodriguez George

[@TheMidnight96]

my chemistry teacher expect A's from all of us, when she cant teach at all.. its like writing a research paper without knowing the alphabet so this is letter A-F

[@muscmrk889]

watching this video in 2x speed makes Sal sound like he's going insane

[@highexposure]

thank you. youre doing more good than you realize with these videos. youtube needs more members like this

[@ranjitn159]

How are you doing sir?

[@ProPaki]

Can A Oxidation state of any element be zero?

[@bluecheesybob]

That's just wrong. It depends on how many electrons you need to achieve a full valence shell. Halogens have oxidation state of -1 because it needs 1 more electron to have full valence.

[@bluecheesybob]

Combining elements doesn't mean you lose electrons. They are shared between those elements, something known as a covalent bond. Watch some earlier videos of Khan's chemistry playlist to get what I'm talking about. Also I'm pretty sure all the noble gases have an oxidation state of 0 since they do not need or want to give up electrons.

[@lovewood2soundgood77]

Pure metals (Al, Fe...), pure nonmetals (S, P, N2, H2, Cl2...) and noble gases (He, Ne, Ar...) have oxidation state zero.

[@tanmaykhelkar7936]

OP Sweg Boi you're wrong. Oxidation state of any pure element is always 0

[@rose2kiss]

i totally get oxidation now there was no explanation given at the unit we got at all thank you so much!

[@DaveReamer]

OIL - oxidation is loss of e- RIG - reduction is gain of e- a better mnemonic IMO (in my opinion)

[@4givenz]

or just remember OIL RIG : Oxidation Is Loss (of electron) and Reduction Is Gain (of electron)

[@cassiusmarley9180]

funny ho he refers to elements as people - to some people - they may consider them friends!

[@jackmcelroy4676]

I finally have a reason to be thankful for Bernie Madoff

[@wizardtech1]

If atoms want electrons so bad why cant they get them from free electrons in electricity

[@TheBigbees]

Thank you!!! The oxidation/reduction concept was driving me insane in class!

[@sciencenerd7639]

I just love that Bernie Madoff analogy

[@kyro909]

I don't understand how the oxygen took an extra electron from someplace else.

[@seventhwave87]

What does he mean that the oxygen gets an electron from somewhere else? where??

[@muntaha97]

Please team up with Collins and write the next AS&A2 text books!! your a legend

[@smitty16082]

Oil Rig Oxidation is losing (electrons), Reduction is gaining (electrons)

[@attaebrahimi6925]

LEO the lion says GER, Lose Electrons Oxidation, Gain Electrons Reduction

[@miinyoo]

Bernie Madoff metaphor is pretty good.

[@KattSavedTheTriforce]

LEO the lion goes GER lose electrons-oxidiation gain electrons-reduction

[@ManasJaipuria]

when this video came out, i was not born

[@kisho2679]

What implications have oxidation state 3?

[@henryjunior38]

Thanks a lot for your tutorials are very helpful everyone is thankful

[@mysteryp1998]

cool.... but your voice makes me go all sleepyy... o.o Zzzzz......

[@Sigmath_Bits]

I was so hocked on your videos I almost forgot to Subscribe! Sorry.

[@rich_aathinks]

God, this video is..... 12 years old!🙄

[@PrivacyKingdoms]

oil rig (oxidation is loss, reduction is gain)

[@RayBabol]

OIL RIG (oxidation is loss, reduction is gain (of electrons))

[@BRBallin1]

basic shit. I wanted oxidation-reduction reaction problems...

[@heh7817]

oil - oxidation is loss rig - reduction is gain

[@tanishahir6381]

the fact you told oxygen not always to every time cleared my 75% doubt thank you so much

[@hocadidilyocutt]

11 members of Bernie's family disliked this video.

[@lucylu21ful]

I'm laughing about the Leo the lion thing cause i remember my chem teacher in hs using OIL RIG but this one is wayy better

[@kptalismus]

OIL RIG - oxidation is loss, reduction is gain!

[@SoSeo4321]

OILRIG - Oxidation Is Loss. Reducation Is Gain
