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 A 77.3-mL sample of this solution was withdrawn and titrated with 0.0573 M HBr. It required 80.4 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?

A solid hydrate of Ca(NO3)2 is to be analyzed (Ca(NO3)2 •XH2O). A sample of the hydrate is weighed in a clean, dry and covered crucible. When empty, the crucible and cover are heated to a constant weight of 30.2016 g. The mass of the crucible and sample is 33.2255 g. The crucible with sample is heated (to drive off the water of hydration) to a final constant weight of 32.2995 g Table 1: Mass Data for the Analysis of a...
