Recall that Ksp is an equilibrium constant related to slightly soluble ionic compounds.
The dissociation of slightly soluble ionic compounds in solution is as follows:
MnNm(s) ⇌ n Mm+(aq) + m Nn–(aq)
Remember that solids are ignored in the Ksp expression.
Sr3(AsO4)2(s) → 3 Sr2+(aq) + 2 AsO43-(aq)
At a certain temperature, the solubility of strontium arsenate, Sr3(AsO4)2, is 0.0610 g/L. What is the Ksp of this salt at this temperature?
