Chapter 15: Equilibria of Other Reactions

Question 1

what is the equation for solubility?

Answer 1

S=mass/volume

Question 2

when is Ksp useful?

Answer 2

when discovering what solubility is

Question 3

what way do large K’s favor?

Answer 3

they almost always favor going forward

Question 4

what is sulfur in a Ksp equation?

Answer 4

it is a very strong base and is never in a Ksp equation alone. [X][HS-][OH]

Question 5

what happens when Q > K?

Answer 5

precipitation occurs

Question 6

what happens when Q < K?

Answer 6

dissolution occurs

Question 7

how to find solubility from Ksp

Answer 7

find the K equation for the compunds, then divide and root solubility

Question 8

how to find Ksp from solubility

Answer 8

find the K equation, then multiply and square it

Question 9

the K of a concentration of a solution of the uncomplexed metal ion will be the lowest in what situation?

Answer 9

when the K has the highest exponent

Question 10

when calculating Ksp from solubitity, what should you note?

Answer 10

that the solubility is in molarity (mol/L) and not in any other unit, if it is, you will need to change it
