Which of the following is correct relationship between solubility and solubility product for silver oxalate ?
Options
- AS = [3] K_ sp 4
- BS = [3] 4 K_ sp
- CS = [3] K_ sp 4
- DS = [4] K_ sp 27
Correct answer
C. S = [3] K_ sp 4
Step-by-step solution
The chemical formula of silver oxalate is Ag₂C₂O₄ . The dissociation reaction is: Ag₂C₂O₄(s) 2Ag^+(aq) + C₂O₄²⁻(aq) Let the solubility of silver oxalate be S . Then, [Ag^+] = 2S and [C₂O₄²⁻] = S . The solubility product K_ sp is given by: K_ sp = [Ag^+]^2 [C₂O₄²⁻] Substituting the concentrations: K_ sp = (2S)^2 (S) = 4S^3 S^3 = K_ sp 4 S = [3] K_ sp 4 Answer: S = [3] K_ sp 4
