Question

Which of the following is true of the solubility product constant?

A. It is an equilibrium position.
B. Its value changes in the presence of a common ion.
C. It is an equilibrium constant.
D. It is the product of the initial concentrations of the ions in a solution.

Answer 1

@Hoslos @rvc

Answer 2

i dont remember :/
maybe B

Answer 3

The constant determines the way moles dissolve per litre of a solution.

Answer 4

So which one is it? @Hoslos

Answer 5

D.

Answer 6

It was C.

Answer 7

My mistake.

Answer 8

It's okay :)

Answer 9

For an endothermic dissolution process, which of the following would you observe on cooling a saturated solution by 10°C?

A. An increase in precipitation
B. A decrease in volume
C. An increase in solubility
D. A decrease in pressure

Answer 10

I am not sure about this one.
What do you say @sweetburger ?

Answer 11

Well if the dissolving process is endothermic that means energy is a reactant. If we are cooling the solution then we are taking energy out which is decreasing the amount of reactants which induces a stress on the system which would in turn cause more reactant to be formed which would result in precipitation.

Answer 12

Thats just my idea though.

Answer 13

So which one?

Answer 14

I think it should be A.

Answer 15

Thanks!

Answer 16

How about this one?

Answer 17

Well the salts with the largest Ksp value will come first which would be Salt D with a very large Ksp of 38.65. Then second would be A with a Ksp of 9.21x10^-8. So the list so Far Is D,A and then the only answer choice which is arranged like this is D. being D,A,B,C. If you continued to look at the Ksp of the remaining salts you would notice that D,A,B,C holds true.

Answer 18

Thanks! This one?

Answer 19

keep up the good work guys @sweetburger @Hoslos

Answer 20

D

Answer 21

am i right?

Answer 22

I disagree as CaF2 has a greater Ksp than CaCO3.

Answer 23

lol messed
yeah correct
C

Answer 24

What is the nature of a solution when it has reached its solubility equilibrium?

A. The solution is saturated.
B. The temperature of the solution always rises.
C. The solution is undergoing precipitation.
D. The Ksp of the solution is greater than its Q.

Answer 25

A.

Answer 26

I agree with @Hoslos

Answer 27

i go with A

Answer 28

In which of the following cases will there be precipitation?

A. Q < Ksp
B. Q = Ksp
C. Q << Ksp
D. Q > Ksp

Answer 29

D ?

Answer 30

I agree with @rvc.
