The table shown gives the solubility product constant (Ksp) for a few salts of mercury. ?
From the table, which saturated solution has the greatest value for [Hg+]?
Hg2Br2 6 × 10–23
Hg2F2 3.1 × 10–6
Hg2Cl2 1 × 10–18
Hg2I2 5 × 10–29

This is actually a poorly-worded question. The technically correct answer would be none of them. In a solution involving mercury(I), the correct cation in solution is Hg2^2+, not Hg^+.

All of the four salts have the same formula type, i.e. A₂B₂. Hence, their solubility can be directly compared by means of Ksp. The greater the Ksp, the higher the solubility is and thus a high [Hg⁺].
Hg₂F₂ has the greater value for Ksp. Hence, the saturated solution of Hg₂F₂ has the greater value for [Hg⁺].
