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 A 78.7-mL sample of this solution was withdrawn
and titrated with 0.0696 M HBr. It required 68.0 mL of the acid
solution for neutralization.

a) A student A weighed .50 Ca(OH)2 for his saturated solution
and student B weighed 0.23 g, Both students dissolved it in 60 ml
of water and both had solid left in their solution before
filtrating. After filtrating to a clear solution, which student had
the most concentrated solution? What would the effect on the volume
of HCl titrant used and the calculated Ksp of the reaction if one
of the students had a couldy solution after filtering and proceeded...
