Question

I need help with What is the solubility of silver oxide, Ag2O, in a solution buffered at pH 10.50? The Kc for the following equilibrium is 2.0 x 10-8. Express your answer in g/L

Ag2O(s) + H2O(l) ¡ê 2Ag+ (aq) + 2OH- (aq)

Answer 1

Write the expression for Kc.
Kc = (Ag^+)^2(OH^-)^2
Substitute H^+ for a pH of 10.50 and solve for (Ag^+)
