The of and type salts (stoichiometry 2:3) with solubility '' evaluates to: | Ionic Equilibrium — Chem-Mantra

Question

The $K_{sp}$ of $Al_2O_3$ and $As_2S_3$ type salts (stoichiometry 2:3) with solubility '$s$' evaluates to:

Answer: C

💡 Solution & Explanation

For $A_2B_3$, $x=2, y=3$. $K_{sp} = 2^2 \cdot 3^3 \cdot s^{(2+3)} = 4 \cdot 27 \cdot s^5 = 108s^5$.
