Question

How do you calculate Ksp?

Answer 1

See this [old answer.](https://socratic.org/questions/what-is-ksp-in-chemistry)

Explanation:

As explained in the link, `K_(sp)` is just another equilibrium constant:

`MX(s) rarrM^+ + X^-`

`K_(sp) =[M^+][X^-]`

`[MX(s)]` does not appear in the expression, because we cannot speak of the concentration of a solid.
