  1. How many moles of calcium hydroxide dissolve to generate one mole of dissolved calcium? Given your answer to CTQ 10 and the concentration of calcium in the final solution calculate the mass of calcium hydroxide that can dissolve in 1 L of our 1.0 M solution of sodium hydroxide? (calcium hydroxide MW = 74.09 g/mol) Compare the solubility of calcium hydroxide you just calculated to the solubility of calcium hydroxide in pure water. By what factor did the “common ion” drive down solubility?

ksp = 1.3 x 10-6
