17.4 Solubility and Ksp

[@codygruberg7294]

i wish u were my teacher. clear and simple

[@ChadsPrep]

Glad you found it helpful Cody!

[@eldanzhangirov2185]

You have such an energy! Thanks for breaking up this interesting topic into easy steps, so everyone can understand this! Greetings from Kazakhstan/Hungary!

[@ChadsPrep]

Thank you!

[@ivakristo3336]

You might have just saved me because my inorg chem final is tomorrow. Thank you so much this was amazing!!

[@ChadsPrep]

Glad you found us, Iva - good luck on your final!

[@Ashley-kl9vj]

You always save the day! I typically look for your channel when learning chem but forgot for this exam, I was really lost on this topic because none of the other videos on youtube on this topic are explained this well... luckily I remembered your channel last minute and I finally get it all. Thank you so much!

[@ChadsPrep]

Happy to hear, Ashley - glad you remembered us! Happy studying!

[@billymeeks845]

Love how you tackled solving for molar solubility AND Ksp "side-by-side" on whiteboard... Very good for outlining the comparison!

[@ChadsPrep]

Glad you liked it, Billy!

[@billymeeks845]

@@ChadsPrep Of course, I’m scoping your redox rxn vids as well :)

Been struggling with this for a while. Watched khan academy, done Ak lectures but it wasn't until here that it finally clicked why we use 2x^2, or why ICE charts were necessary. Thanks Chad, keep up the good work.

[@ChadsPrep]

Awesome Devin! Perseverance is the key to much in life. Keep it up!

its awesome that he has almost as many subs as views, I found the video really clear and helpful, thanks Mr Chad

[@mdiakite5959]

Thank you Chad. Your pedagogical approach is awesome

[@ChadsPrep]

Awesome M. Glad you're finding these helpful!

[@abigailalvarado9507]

thank you so much. My professor literally doesn't teach, so your videos really help me grasp the concept.

[@ChadsPrep]

You are welcome so much Abigail! So glad you're finding these helpful in filling in the gaps!

[@flamepoint8456]

You are explaining more better than any man of the world can. Thank you!Your teaching skills are really a lot better than any of the common teacher.. In which country do u live, I want to come there. I don't know better English as I live in INDIA

I lost him around 14:40. Basically if there is a multiple choice question asking which one had the lowest solubility, and the answer choices were AgCl, Mg(OH)2, and BiI3, you would have to compare the X's? Since the lowest X was AgCl's, then that would be the one with the lowest solubility? I know X is for Molar Solubility, and Ksp is Solubility Product. But what do they entail that makes a difference between the two? And why do we have to compare the X's when the compound breaks up into a different amounts of ions, instead of just using Ksp?

[@ChadsPrep]

X is the molar solubility or simply the solubility as it is the concentration of solid that dissolves into solution. So if you're comparing the solubility of two compounds it is this value that you should be specifically comparing. But compounds that dissociate into the same number of ions will have the same mathematical relationship between the value of 'x' and the Ksp. In such cases the one with the higher Ksp will also have the higher 'x' value and so you could just get away with comparing the Ksp vales. This would work when comparing AgCl to AgBr or SnS as they all dissociate into 2 ions. Or it could work for comparing Ag2S to BaF2 as they both dissociate into 3 ions. But if you were to try to compare AgCl to Ag2S which dissociate into a different number of ions, you're going to want to calculate the 'x' values rather than compare the Ksp values. The mathematical relationship between 'x' and Ksp will be different for them and the one with the higher Ksp is may or may not have the higher 'x' value (and the higher solubility). Hope this helps!

Wait....at 14:03, where does that 27 come from? Everything else is 100% clear but I was totally lost at that part :(

[@eduardomontes7705]

Would the idea that you mentioned at the end of the video be related to the Van Hoff Factor? The whole idea concerning the 3 reactions breaking up accordingly into (x^2), (4x^3) and (27x^4)?

[@ChadsPrep]

I'd never considered relating it to the van't Hoff factor, but you total could. i=2 Ksp=x^2 i=3 Ksp=4x^3 i=4 Ksp=27x^4 Nice call!

[@eduardomontes7705]

Thank you! I appreciate your videos a lot! Great MCAT review!

Nice . quite cool :) helful

isn't Iodine always soluble except with silver, lead, or mercury? why doesn't bismuth iodide completely dissociate?
