Question

Mg(OH)2 is a slightly soluble salt what is the Ksp expressi a. [Mg2+][20H J? b. (Mg2+][OH-]2 c. [Mg2][OH-] d. [Mg2][OH-]?

Answer 1

Its A

Step-by-step explanation:

Answer 2

B)
`k_(sp) =[Mg_(aq) ]*[OH_(aq)]^(2)`

Step-by-step explanation:

Ksp is the solubility product constant.

For a generic chemical equation

`AB_(2) = A_(aq)+2B_(aq)`

The Ksp for this generic chemical equation is

`k_(sp) =[A_(aq) ]*[B_(aq)]^(2)`

So the Ksp fot the Mg(OH)2 is

`k_(sp) =[Mg_(aq) ]*[OH_(aq)]^(2)`
