What is the solubility product expression (Ksp) for silver chromate (Ag2CrO4) dissolving in pure water?
Answer and explanation
Correct answer: C. Ksp = [Ag+]^2 * [CrO4^2-]
Ag2CrO4(s) <=> 2 Ag+(aq) + CrO4^2-(aq). The equilibrium constant expression incorporates ion concentrations raised to their stoichiometric coefficients: Ksp = [Ag+]^2 * [CrO4^2-].
