(a) A sample of solid Ca(OH)2 is stirred in water at 30°C until the solution contains as much dissolved Ca(OH)2 as it can hold. A 100.-mL sample of this solution is withdrawn and titrated with 5.00 ✕ 10−2M HBr. It requires 48.8 mL of the acid solution for neutralization. What is the molarity of the Ca(OH)2 solution?
(b) What is the solubility of Ca(OH)2 in water, at 30°C, in grams of Ca(OH)2 per 100 mL of solution?
