Question

calculate the initial pH of the solution given the following reaction.

Ca(OH)2 -> Ca2+ + 2OH- with ksp= 1.3 x 10^-6

please explain how you got your answer.

Answer 1

Answer #1

15 Ca (OH), means it completely is sparingly soluble in water does not dissociate the content into water. Ksp = 1.38106 → Cos pH=11.8
