Thanks very much

[@callisastapp7160]

legitimately tho XD

[@neoamuro1348]

Lol thats truu

[@shadowpanda3748]

God i wish i had found this channel sooner. I wouldn't have failed so many tests because you're better at explaining things than my chem teacher. Thank you!

[@mmoonchild276]

So ri8

[@itnightthebest7638]

Nah facts but it made it worst since im in Ap chem now and the teachers just expects you to know more than you do and remember things more than you were taught

[@IOS6Jailbreaker1]

you are a life saver, honestly University lecturers go in Eminem speed level because of time limit. thanks so much keep up the good work

[@disharudraa8714]

Actually..

[@Madifishy]

The way my professor explained calculating oxidation numbers was so confusing and difficult to follow, but this video was so thorough in explaining how to calculate oxidation numbers and was extremely helpful! Thank you so much!

[@akshs9085]

redox was taught to us in class today, and i understood nothing, felt super demotivated and dumb for not understanding what everyone did. came home and watched his videos and actually understood, this comes to show that we are not "stupid" with the right guidance we can all do well!

[@kairy7308]

My professor tried teaching this to me like 3 times and nothing! I watch 5 minutes of this and I got it! Best educational KZbin channel hands down!!!

[@Elsa-vn1yg]

This is the best channel ever. I love his voice. I love his explanation form. This helped me a lot. Thanks ♥️

[@callisastapp7160]

the color coded numbers and stuff too, very helpful

[@charlemengsimon8645]

Heyyy nice to meet you

[@HanovilleSpecialistHospital]

Real bro best teacher ever❤❤❤

[@quinnzoee]

I started understanding this at 6:00 !!! TYSM my chemistry teacher is the worst and I learned more in 6 minutes than 2 days in class!!♥️♥️♥️

[@anojaranathunga4365]

Lol same😂

[@आर्यन_गड़वाल]

Same 😆

[@magicfairycome]

this channel is singlehandedly carrying me through college chemistry :) thank u so much, somehow your explanations are 1000x more understandable and LESS BORING than my lectures, even though I love my teacher. I basically ignore allllll my school material and just focus on finding patterns in the steps in solving problems, and you seem to understand that more than anyone. You give me EXACTLY what I need to understand the patterns, and you do it so fast that my ADHD brain is able to stay focused! So bloody perfect

[@kachicelestine9659]

Thank you, sir. Whenever I want to solve questions relating to calculations the channel that comes to my mind is The Organic Chemistry Tutor. You are doing a great job. I appreciate your effort in educating us here on youtube.

[@ngozipearl6269]

Awesome! This is something I have been cracking my head for days and within 30 mins, I learnt it. Thank God I discovered this organic chemistry tutor. He is so good. Chemistry is no longer my nightmare.

[@oluyedeemmanuel415]

Am in the university and for 12 years I have battled passing chemistry, learnt more on this channel in 5mins than all my years of study, always lucky to pass it in school then

[@xhmbx9548]

FINALLY UNDERSTOOD HOW TO CALCULATE OXIDATION STATES!!! THANKS

[@Littlemilkdud]

I watched another chem KZbinr's way of finding the oxidation state, but it was way too complicated for me to understand. You made it way simpler, so thank you!

[@EpicEHighlights]

I've learned so much about oxidation numbers in 1 video than throughout my school. Thank you very much!!

[@saint.dxnijxl]

I love this man! Not only do his eloquent explanations aid students in their science classes, but he manages to convey these concepts as logical as possible.

[@georgesadler7830]

Professor Organic Chemistry Tutor, thank you for a Basic Introduction on How to Calculate Oxidation Numbers in AP/General Chemistry. Knowing the electronegativity of elements, the Ions and polyatomic ions sheet is an excellent way to calculate oxidation numbers. This is an error free video/lecture on KZbin TV with the Organic Chemistry Tutor.

[@sm-65datlas23]

Very detailed and full of examples! Thank you I've learned a lot and now I think there's hope for me in Chemistry hahaha

[@hankyje117]

Felt like I could never learn this, you make everything so much easier!

[@hrishavsahamusic1868]

If i get 100% in my General Science 10th board exam ( which is in 2 weeks time), i'm attributing you with the credit! I learnt more about oxidation numbers in this half an hour, than my entire year at school. In lesser words, THE BEST HALF AN HOUR EVER SPENT! LOVED IT!!!!!!!!!!!!

[@annego3656]

I watched this as a rewind before the new school year and I understand them better than after 2 months of school. Amazing work, thank you.

[@emiliuxltu1655]

goodness gracious thank you so much! i wasn't sure at first about a 30 minute video but this 30 mins helped me more than a week at college!

[@aaronwilliams9008]

This man deserves all the good things... this channel is the best thing that I ever found to help my with my Chemistry degree ❤

[@JaneFrances-pm1nm]

I can't believe that I'm really the one solving oxidation num.I can't thank u alot .To be serious u are magnificent ,may God continue to bless you, Amen.

[@robertn.4379]

Our professor made zero attempts to try and explain this, and only referred to the textbook which did a terrible job at explaining this concept. I re read the whole chapter carefully 3 times before throwing in the towel and looking for help elsewhere. I totally get it now, I just wish I didn't waste so much of my time, thanks for the help!!!

[@User0009qqqqq]

You are the reason why I got all my A's in chemistry... You are amazing!!!

[@ishmaelchristlifemusic2654]

Man you are blessing from God. I learn so much from you in the simplest ways possible. I am a teacher, whenever I come across a concept I feel might be difficult to understand and in turn explain to the kids, I simply have to watch one of your videos and just like that, i got it. God bless you

[@mr.n.3139]

I have learned a lot in this 31 minutes tutorial. Fabulous work!

[@VoltaSlime]

Thank you so much. My confidence for the 2nd test just skyrocketed!! I got an 80% in the previous test because of you! Thanks a bunch!

🎯 Key Takeaways for quick navigation: 00:15 *🧪 The oxidation state of pure elements is always zero.* 01:32 *📜 When dealing with ions like mercury or peroxide, divide the total charge to find individual oxidation states.* 03:43 *🚀 Fluorine in compounds typically has a -1 oxidation state; oxygen usually has -2, unless in peroxides (-1) or superoxides (-1/2).* 05:20 *💡 In compounds like MgCl₂, the total charge of the compound determines oxidation states; Mg²⁺ implies Cl⁻ will be present, resulting in Mg²⁺ and Cl⁻ ions.* 06:08 *🧮 In compounds like vanadium oxide, the term "oxide" implies oxygen will have a -2 charge; calculate the oxidation state of the other element(s) accordingly.* 09:48 *🧲 Electronegativity increases towards fluorine on the periodic table; it determines the distribution of charges in compounds.* 12:40 *🧠 In compounds like oxygen difluoride, the more electronegative element bears a negative charge; oxygen's oxidation state can vary depending on the compound.* 17:45 *📊 Use electronegativity to predict oxidation states; more electronegative elements tend to have negative oxidation states.* 20:32 *🧲 Average oxidation states can be fractional; they represent the distribution of charges among ions in compounds.* 24:24 *🔍 In polyatomic ions like HSO₄⁻, deduce oxidation states based on the charges of known elements within the ion.* 27:36 *📐 In complex ions like K₂CrO₄, determine oxidation states by balancing charges to achieve electrical neutrality.* Made with HARPA AI

[@angeliquedominikaarellano9149]

You are so good in explaining, I've read the book many times, and watched 3 different video tutorials but yours is the only video I already understand all about oxidation states. Good job. I hope to see more of your video tutorials. Whatever chemistry topic, your tutorials are my favorite to consult with.

[@jeonjungkook6584]

Yes you are right :)

[@CluckYou21]

You are the best and are helping me with chemistry for engineers. Its a difficult class but I believe I can obtain a B thanks to you.

Thts true..

[@khadeejaaman4503]

This was so useful. I've been stuck on it for weeks. Thanks a lot!

[@anyataylor9475]

It's weird that Americans are taught to add to both sides in algebra e.g at 7:35 you +8 to both sides, whereas in Britain we're taught to move the 8 to the other side and change from + to - or vice versa. Just a weird little thing I noticed :)

[@sylviaifeomaobi6472]

The same. I’m originally from Spain, now I school in America, and I see that very weird.

[@mohammedmuneeb6888]

That's basically like the proof of how it works rather than an operation. Well, I guess Americans just don't practice enough math.

[@Studyjee-ch3tn]

00:06 Oxidation numbers: pure elements have an oxidation state of zero, ions have oxidation state equal to their charge 02:38 Fluorine and oxygen have predictable oxidation states in compounds. 08:11 The oxidation states of elements within compounds and polyatomic ions can be found by adding or subtracting based on the net charge. 10:40 Electronegativities determine the charge distribution in compounds 15:36 Sulfur dioxide and hydrogen sulfide have different oxidation states. 17:51 Elements with different electronegativities have different oxidation states 22:32 The average oxidation state is 2.67 24:32 Sulfur has an oxidation state of +4. 29:16 Electronegativity determines oxidation state
