Ion Concentration in MgSO4 Solution

Medium General Chemistry Solution Chemistry

In an aqueous solution, the concentration of magnesium ions (Mg²⁺) is 0.02 M, while the concentration of sulfate ions (SO₄^2-) is 0.04 M. Given the dissociation reaction of magnesium sulfate (MgSO₄), which of the following statements is true regarding the relationship between the concentrations of these ions in the solution?

The concentration of Mg2+ is equal to that of SO42-.

The concentration of SO42- is twice that of Mg2+.

The solution is saturated, and additional MgSO4 will not dissolve.

The concentration of Mg2+ will always be greater than that of SO42-.
