Quizplus · Accepted Answer

The solubility of magnesium sulfate can be calculated using the following equation:

Ksp = [Mg2+][SO42-]

where Ksp is the solubility product constant, [Mg2+] is the concentration of magnesium ion, and [SO42-] is the concentration of sulfate ion.

We are given that the MgCl2 solution has a concentration of 0.10 M, which means that the concentration of Mg2+ ions is also 0.10 M. We can assume that the concentration of SO42- ions from the MgSO4 salt is x M.

Therefore, we can substitute these values into the Ksp equation and solve for x:

5.9 × 10^-13 = (0.10)(x)

x = 4.2 × 10^-4 M

Therefore, the solubility of MgSO4 is 4.2 × 10^-4 M, which corresponds to choice A.
