For a binary salt , `K_(sp) =(………)^(2) `

Explanation

To solve the problem regarding the solubility product constant (Ksp) for a binary salt, we can follow these steps:

### Step 1: Understand the Dissociation of a Binary Salt
A binary salt can be represented as AB, where A is a cation and B is an anion. When this salt dissolves in water, it dissociates into its constituent ions:
\[ AB (s) \rightleftharpoons A^+ (aq) + B^- (aq) \]

### Step 2: Define Solubility (S)
Let the solubility of the salt AB in water be denoted by S. This means that when the salt dissolves, the concentration of A^+ ions in solution will be S, and the concentration of B^- ions will also be S.
