A weak acid H ₃ ~A has the three consecutive dissociation constants K₁, K₂ and K₃ in water as 1.0 10⁻⁴, 1.0 10⁻⁸ and 1.0 10⁻¹⁶ respectively at room temperature. A metal M forms salt MA which is sparingly soluble (solubility product 10⁻³⁰ ) in water. It also forms a water soluble chloride MCl ₃ which dissociates into M ³⁺ and Cl ⁻ ions completely in aqueous solution. For an aqueous solution of the acid H ₃ ~A of conce
Options

- BThe H ⁺ ion concentration in the solution is close to (K₁ C )^ 1 / 2 .
- CThe H ⁺ ion concentration in the solution is (3 K₁ K₂ K₃ C )^ 1 / 4 .
- DOn addition of excess of the soluble salt MCl ₃ to the acid solution, the H ⁺ ion concentration in the solutio
