Question

Part A

Calculate the solubility (in grams per 1.00×10^2mL of solution) of magnesium hydroxide in a solution buffered at pH = 11.

Express your answer using two significant figures.

S1 = ______________ g / (1.00 * 10^2 mL)

Part B

Calculate the solubility (in grams per 1.00×102mL of solution) of magnesium hydroxide in pure water.

Express your answer using two significant figures.

S = ______________ g / (1.00 * 10^2 mL)

Part C

How does the solubility of Mg(OH)2 in a buffered solution compare to the solubility of Mg(OH)2 in pure water?

Express your answer using two significant figures.

S1/S = _______________

Answer 1

Part.C:

The solubility of buffer solution is less compare to solubility in pure water due to common ion effect.
