What is the solubility of caoh2 in water at the, Ask an Expert

Academics

A sample of solid Ca(OH)2 was stirred in water at a certain temperature until the solution contained as much dissolved Ca(OH)2 as it could hold. A 63.1 mL sample of this solution was withdrawn and titrated with 0.0615 M HBr. It required 98.5 mL of the acid solution for neutralization. (a) What was the molarity of the Ca(OH)2 solution? (b) What is the solubility of Ca(OH)2 in water, at the experimental temperature, in grams of Ca(OH)2 per 100 mL of solution?
