\(MY\) and \(NY_3,\) two nearly insoluble salts, have the same \(K_{sp} \) values of \(6.2 \times 10^{-13}\) at roomtemperature. Which statement would be true in regard to \(MY\) and \(NY_3\) ?
- A The salts \(MY\) and \(NY_3\) are more soluble in \(0.5 \,M\, KY\) than in pure water.
- B The addition of the salt of \(KY\) to solution of \(MY\) and \(NY_3\) will have no effect on their solubilities.
- C The molar solubilities of \(MY\) and \(NY_3\) in water are identical.
- D The molar solubility of \(MY\) in water is less than that of \(NY_3\)
Answer & Solution
Correct Answer
(D) The molar solubility of \(MY\) in water is less than that of \(NY_3\)
Step-by-step Solution
Detailed explanation
For \(M Y: K_{s p}=s_{1}^{2}\) \(\Rightarrow s_{1}=\sqrt{K_{s p}}=\sqrt{6.2 \times 10^{-13}}\)
