Solubility

Question 1

What does smaller ksp mean

Answer 1

Favours reactants, less soluble

Question 2

Lager ksp means?

Answer 2

More soluble, favours products

Question 3

The solubility can be compare only when:

Answer 3

Salts have the same cation to anion ratio

Question 4

Ph effect on solubility: what happens if you decrease ph in mg(oh)2

Answer 4

Oh decrease and equilibrium shifts to the right. So more products, more soluble

Question 5

If Q<Ksp solution is

Answer 5

Unsaturated (can add more to solution)

Question 6

What is the solution if Q = Ksp

Answer 6

Saturated

Question 7

What is the solution if Q> Ksp

Answer 7

Precipitation will occur

Question 8

What is supersaturation?

Answer 8

Adding too much salt to water and crystals are left at the bottom. If add a crystal to the solution, solution solidifies to crystal structure

Question 9

What to do for predicting precipitation questions

Answer 9

Find the final concentrations of the end product in question, then find q and check if greater than K

Question 10

What to do for common ion solubility

Answer 10

Add up the concentrations of the common ion (0.1 M br2 turns into 0.2) then find x for the ice table.

Through x, find the concentration of the solid and then divide by litres to find mols
