We've learned that some ionic solids are totally water insoluble, but in fact this is a slight oversimplification. Even such solids will dissolve to some minuscule degree, and we can measure this, and do calculations with it. Let's learn about solubility product constants!

@faeidhussain2657 3 года назад

why to raise the molarity to the power of stoichiometric component?

@natan-elmensahsowah4581 Год назад

Thank you !! However, I have a question. I understand that for (OH)2 in Ca(OH)2, 2 is the coefficient for OH and becomes its exponent when calculating Ksp. How do you decide to use the subscript as a coefficient. I was wondering why in the last question PbI2, 2 was used as the coefficient? The reason why I am confused was because in the CaCO3 example, 3 was not used as a coeeficient : just [Ca][CO]?

@arduino_8829 Год назад

This may be a bit late but that's because carbonate is a polyatomic ion. CaCO3 is one calcium (Ca) and one carbonate (CO3). If it were Ca(CO3)3 then there would be three carbonate ions and the exponent would be 3, [Ca][CO3]^3. This means that the Ksp expression would be Ksp=(x)(3x)^3. Because the carbonate is not separating into individual molecules, it is functionally just another ion, similar to iodine.

@marislox1844 2 года назад

If he knew what he was talking about, he would have explained. I suggest not wasting your time with this person's videos.

@Absalonian Год назад

Basically, the subscript becomes the coefficient since the amount of iodine being dissolved is two per molecule. And then using what you learned about icebox earlier you just apply the same concepts. At least that’s what I got out of it.

@Absalonian Год назад

@@marislox1844 I don’t understand why a few people not being able to understand the explanations provided in the video automatically discredits “this person’s” entire channel. If anything, ask for whatever wasn’t understood to be cleared up.

@sofia4933 Год назад

for 7:00 why is the Ksp 4x^3 and not 2x^3 ??

@Finnnloafin 11 месяцев назад

(2x)^2 is the same as 2x times 2x, so you can solve that part by multiplying the 2's and the x's together, making 4x^2. Then you multiply that by the last x which makes 4x^3. Hope that helps!

@theredmonkey236 3 года назад

I have two questions: 1.For your first example problem (6:00) when you broke down CuBr into Cu and Br you didnt put a subscript of 2 on Br. isn't Br diatomic? 2.In the Ksp formula do subscripts count as coefficents and go above the element? Or in the ICE table do you count them as a coefficent?

@ProfessorDaveExplains 3 года назад

Molecular bromine is diatomic. CuBr is an ionic compound consisting of one ion of each element. Coefficients that apply to each ion become exponents in the formula.

@theredmonkey236 3 года назад

@@ProfessorDaveExplains So are diatomic rules ignored when you break down a ionic compound?

It's just a totally different compound. It has nothing to do with this one.
