Which of the following is the correct mathematical expression for the Solubility Product () of a spa — Ionic Equilibrium Chemistry Question
Question
Which of the following is the correct mathematical expression for the Solubility Product ($K_{sp}$) of a sparingly soluble salt of type $A_x B_y$ with molar solubility $s$?
Answer: B
💡 Solution & Explanation
For $A_x B_y \rightleftharpoons xA^{y+} + yB^{x-}$, the equilibrium concentrations are $[A^{y+}] = xs$ and $[B^{x-}] = ys$. $K_{sp} = [A^{y+}]^x[B^{x-}]^y = (xs)^x(ys)^y = x^x \cdot y^y \cdot s^{(x+y)}$.
