The Common Ion Effect

[@theCodyReeder]

Once upon a time I knew this.

[@ZeynebAbd]

Why learning again ?

[@Nahin-iy4cy]

Damn

[@rekhasharma6840]

Anyone else having there chemistry exam tomorrow....

[@linabora1022]

Yes

[@musicloverhayat8402]

Me😭😭😭

[@mukelabainalukui5226]

Today 🥺😭😭

[@1nonlyvii]

In 3 hours actually 😭

[@ramsaran3565]

Yes

[@manaywave]

Got carried away by the new look 😂❤

[@saronsolomon7524]

rightttt... the first thing i noticed😂😂

[@ilong4rennes]

thx a lot, i don't understand this concept in class but you use 4 minutes to explain this so clearly.

[@na-chan163]

I clicked because of the haircut!!!! #clickbait 🤣

[@lailatulqadrm217]

Same here. Shock!

[@wholestself8790]

Same

[@moonblade6230]

Me too

common hair effect .d

[@ecozeek363]

I appreciate these videos. You do a great job introducing chemistry and science concepts. I use them all the time for summary in my NGSS STEM Chem class. Thanks!

[@dagova_atacama]

Yes... Ions are easy when the handsome profesor Dave explains..

[@KofteG61]

Wow you got a new haircut, looks good! Funny how hair can make people look so different.

[@Maryam-om7gt]

absolutely right 😂

[@girlyboss703]

Final exam in under 12 hours and this just saved me so much stress, thank you !!!

[@gabriellepadley3015]

Damn, Professor Dave. Lookin' good

[@VyvienneEaux]

At first I didn't understand how to use the common ion effect quanititatively, so I paused the video as soon as you said "quantitative," went away for two days, and came back knowing how to do it using the Ksp expression (without having finished the video until today, which confirmed my hypothesis). It's amazing how much we integrate and learn in diffuse mode.

[@cyberchampion2675]

Except I forget to come back to where I paused lolol

[@ihka4767]

Hi Professor Dave! I love your videos and also your haircut XD, you just earned a new sub!

[@fortnitegamer7999]

This was the last topic on my exam syllabus and after finishing the rest of the syllabus I still couldn’t understand the concept and that’s when I found this video. Thanks a lot Professor Dave

[@MariaClara-ih4nn]

omg first time seeing professor dave like this

[@michaelmichael9623]

THE HAIRCUT!!!!! PROFESSOR DAVE HAD HIS HAIR CUT!!!!!

[@ahmedsarker3555]

1:15 why do we add potassium iodide we could have applied a different iodide compound not specifically potassium iodide and 2:06 where did cadmium bromide come from. 3:29, why do we have to root the value 1*10^-28

[@boxer8657992]

Holy crap. You look better brother. Keep this

[@KaamilNaicker]

Nice haircut! Thank you for helping me to pass organic chemistry. Great video too, Professor Dave

[@kawanganyirenda452]

Wow !!!! Thank you so very kind. I was missing out one point ending up getting wrong values as I failed to understand when studying alone using Zumdah Zumdah..... expecting more from you Professor Dave

[@furqanqayoom8556]

anyone here in 2024

[@arslanrajput5142]

Present

[@faizarehmat371]

Thank you sir frm bottom of my heart .short video but great Explaination..your leacture is really fruitful for me .love frm Pakistan ♥️♥️

[@maemoonaarshad1952]

paper ke tayari ho gaye😂😂😂

[@anonymousscientist7912]

1:45 the addition of KI increases I- concentration, so the reaction shifts left. Why doesn’t the K+ in KI affect the shift? Is it because it doesn’t react with anything on either side?

[@ProfessorDaveExplains]

yes potassium is inert in this case

[@DrKhan-wv9xg]

hmmm

[@pboyzzadventures3185]

Common ion effect is an application of Le Chateliers Principle. If we were to add one component the equilibrium will shift to one side and add to that side. Two compounds sharing the same ion adding them to a reaction will promote precipitation.

[@ふぉぐらいだ]

what is the difference between Le Chateliers Principle and Common ion effect. i am japanese

[@saucyurgranny1737]

Y'ALL sleeping on my boy Dave...he always hit different 😘

[@Amythestz]

his haircut got me simpin over Prof Dave 🥺

[@ahmedjahenzaib148]

i am literally stunned at how you made it look so simple.....YOU ARE AN ALIEN....Amazing video...i used to criticize you...more love to you!!!

[@garlic98]

Ur channel is saving me for mcat

[@saifulsonia3650]

Your videos are helpful and easy to understand 😮 please give explanation on quantitative chemistry equivalent to A levels

[@srijibchakraborty4345]

Nice Brother .

[@rohithn1812]

Thank you for uploading beautiful explained videos And I loved your new hair cut

[@4m0d]

your videos are super concise and epic

[@mahimoeen7620]

I use to watch ur videos all the time it's very helpful...by the way nice haircut 💯

[@andrewhandelsman834]

Hi Professor Dave!

[@Hlebuw3k]

KZbin just recomended this to me and its 275 views I guess youtube knows i love science

[@Schlohmotion]

You will get many more of his videos in you recommendations.

[@georgesunnyvarkey3425]

Thanks Dave I learned a good amount from your videos

[@jamieanan-ua5994]

Great video dude!

[@phenomenalphysics3548]

In the ksp expression, why haven't we divided it by concentration of CdS

[@ritankarmondal0411]

Because CdS is in the form of precipitate (solid) and the active mass of solid is 1. So we don't include that while writing the ksp expression.

[@shifbread]

Don't believe him.. He isn't professor Dave.. He's one of his clones 😂😂😂

[@ethanrobertson1434]

Great job man!!! Keep up the good work!!!

[@hiitsmichael.]

L comment

[@niaambursley5704]

Does the molar solubility of AgI and KI decrease, or does the solubility of AgI decrease and the solubility of KI increase? Is it possible for KI to precipitate out when its added to a solution of AgI? I think the slightly less soluble salt precipitates first but if the saturation point of the solution is exceeded then both salts form precipitate.

[@starofthesea2028]

Hello professor Dave! I bring you mind boggling chemistry question if it is ur willing Let me explain the question and i want satisfactory and simple tangible answer Q: In Our chemistry lesson i.e "Acid-Base equilibria" we have learned about acid-base conjugate with their strength (based on Bronsted-Lowery acid base pair) so #1👉)if HA (Hypothetical Acid) is weak, it's conjugate base will be stronger than it's source acid i.e HA, again #2👉 if HB (hypothetical base) is weak, it's conjugate acid will be much stronger than HB. #3👉 if HA is strong, the conjugate base will be weak #4👉 if HB is strong, it's conjugate acid will be weak #5👉 also Ka & Kb are directly proportional to the strength of acid and base (i.e when the value of Ka & Kb increase acid and base strength also increase ) Based on this as we know NH₃ is weak base and it's conjugate acid must be stronger and must contains higher Kb value. However NH₃ which has Kb value 1.8×10¯⁵­ i.e higher than it's conjugate acid i.e ka value of 0.556×10¯⁹. so even if we use big approximation we get the ff 🔵Kb=10⁴ka according to the above definition the value of NH₄ (conjugate acid) must be much larger than it's source base. Why is this so? according to the above 5 definition doesn't it contradicte? as i mentioned i need deep clear and convince answer rely on book (also you have to make a video on this topic )

[@shreya6107]

was awesome understood very well thank you so much

[@razasyed575]

brochago your the man

[@heraldjames6545]

New lesson New haircut 🖒

[@yuta2349]

This was very helpful :)

determine the ph of 1.0 M KF. the value of hf is 7.2 × 10−4

[@johnwilkinson5564]

Thanks professor dave :)

[@kevinnguyen1133]

You should start an MCAT series!!

[@ProfessorDaveExplains]

I plan to do that at some point!

[@genicadelara5243]

I was shocked by the new haircut.😅❤

[@davewang2982]

Final is tmmr, this is helping a lot lol

[@studycircle5999]

That's great man

[@AbrhamTaye-h8f]

thank you

[@inamdarsaquib9528]

Thank you soooo much savior.

[@yashodeepwable9142]

Really love u r videos keep it up Were supporting u :)

[@mushfiqurrahmanshishir8055]

But I think Ksp value doesn't change(does change if only temperature is changed). Kip value increases to equilibria the formula

[@esvanadium7632]

DOPE hair cut ! i missed your long hair

[@aa9987]

Sir why did we added 0.010+x anf not 0.010-x as the molarity will decrease on use?

[@drvir]

The 0.010 M Cd2+ ions were present due to CdBr2. But, there were no S2- ions. When you add CdS, it dissociates into Cd2+ and S2-. Since equal number of both ions are released in this process, we add X to both the concentrations

[@1829Emily]

Thank you professor! the new haircut looks great by the way

[@jamilandrew1821]

Nice Haircut :)

[@surajvodnala4959]

The worst part of the MCAT? Having to relearn Gen Chem stuff you thought you were done with :(

[@nhuyn6556]

Thanks bro
