The solution becomes negatively charged due to the majority $\text{Cl}^-$start text, C, l, end text, start superscript, minus, end superscript ions.

The solution becomes positively charged due to the stronger $\text{Mg}^{2+}$start text, M, g, end text, start superscript, 2, plus, end superscript ions.

The solution remains neutrally charged.

The solution becomes positive or negative, depending on the relative $\text{Mg}^{2+}$start text, M, g, end text, start superscript, 2, plus, end superscript and $\text{Cl}^-$start text, C, l, end text, start superscript, minus, end superscript concentrations.
