Solubility Equilibrium

Question 1

Calculating the molar solubility

Answer 1

1. Write out the equation and set up an ICE box
2. if no initials are given then they are 0
3. add x to the products and solve for x

Question 2

The effect of pH on Solubility

Answer 2

the solubility of an ionic compound with a strongly basic or weakly basic anion increases with increasing acidity (increase pH)

Question 3

When Q < Ksp

Answer 3

the solution is unsaturated and more of the solid ionic compound can dissolve in the solution

Question 4

When Q > Ksp

Answer 4

the solution is super saturated under most circumstances, the excess solid precipitates out of a super saturated solution

Question 5

Q = Ksp

Answer 5

the solution is saturated. The solution is holding the equilibrium amount of the dissolved ions and additional solid does not dissolve in the solution
