The dissociation of slightly soluble ionic compounds in solution is as follows:
MnNm(s) ⇌ n Mm+(aq) + m Nn–(aq)
where x = molar solubility of the compound.
a) MX ⇌ M+ + X-
Use the Ksp values to calculate the molar solubility of each of the following compounds in pure water.
a) MX (Ksp = 6.99 × 10−11)
b) PbCl2 (Ksp = 1.17 × 10−5)
c) Ca(OH)2 (Ksp = 4.68 × 10−6)
