Question

In a saturated aqueous solution of Ag2CO3Ag2⁢CO3, the silver ion concentration is 2.53×10−42.53×10−4 M and the carbonate ion concentration is 1.27×10−41.27×10−4 M. Calculate the solubility product, Ksp, for Ag2CO3Ag2⁢CO3.

Ksp = ____________

Answer 1

The solubility equilibrium would be: Ag₂CO_3(s) ⇔ 2 Ag⁺_(aq) + CO₃^2-_(aq)

So K_sp = [Ag⁺]² [CO₃^2-] You are given the equilibrium concentrations, so insert the values into this equation and the answer will be K_sp.
