What is the generalized mathematical expression for the Solubility Product () of a sparingly soluble — Ionic Equilibrium Chemistry Question
Question
What is the generalized 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 $A_x B_y \rightleftharpoons xA^{y+} + yB^{x-}$, $[A] = xs$ and $[B] = ys$. $K_{sp} = [A]^x[B]^y = (xs)^x(ys)^y = x^x y^y s^{(x+y)}$.
