What is the molar solubility (in mol L-1) of a salt in pure water with general molecular formula MX (where M is a cation and X is an anion) that has Ksp = 2.22 x 10-5 ?

Answer 1

MX(s) <==> M⁺(aq) + X^-(aq) ... Ksp = 2.22x10^-5

Ksp = [M⁺][X^-]

2.22x10^-5 = (x)(x) = x²

x = 4.71x10^-3 M = molar solubility of the salt
