Question
Which expression represents the solubility product of Silver sulphate, Ag₂SO₄?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Ag₂SO₄(s) ⇌ 2Ag⁺(aq) + SO₄²⁻(aq). Ksp = [Ag⁺]²[SO₄²⁻]. Option B is incorrectly written (should be squared), but among the choices, it is the only one with the correct ions. The correct expression is not listed. If forced, B is closest in form, though it omits the exponent.
Hint
Ksp = product of the ion concentrations, each raised to the power of its coefficient.
