7.11 Introduction to Solubility Equilibria
A student investigates the solubility of three sparingly soluble silver salts in pure water at \(298\text{ K}\). The table below provides the formula and solubility product constant (\(K_{sp}\)) for each salt.
Based on the information in the table, which of the following correctly ranks the salts in order of decreasing molar solubility (from greatest to least) in pure water at \(298\text{ K}\)?
| Salt | Formula | \(K_{sp}\) at \(298\text{ K}\) |
|---|---|---|
| Silver chloride | \(\text{AgCl}\) | \(1.0 \times 10^{-10}\) |
| Silver chromate | \(\text{Ag}_2\text{CrO}_4\) | \(4.0 \times 10^{-12}\) |
| Silver phosphate | \(\text{Ag}_3\text{PO}_4\) | \(2.7 \times 10^{-23}\) |
Based on the information in the table, which of the following correctly ranks the salts in order of decreasing molar solubility (from greatest to least) in pure water at \(298\text{ K}\)?
