Question: Common ion effect experiment: Calcium Hydroxide 0.1M initially Titration 0.1M HCL 0.25 ml Average titre for saturated Ca(OH) 2 + 0.1 M CaNO 3 11.5

Common ion effect experiment:

Calcium Hydroxide 0.1M initially

Titration 0.1M HCL 0.25 ml

Average titre for saturated Ca(OH)2 + 0.1 M CaNO3 11.5 ml

a) Calculate the solubility of Ca(OH)2(s) in 0.100 M Ca(NO3)2(aq)

b) the solubility product.

c.) pH 13.97of the saturated Ca(OH)2 solution in water , calculate the [OH- ] and hence estimate Ksp.
