Question

$MgC{l}_2$ can be dissolved by which of the following solvents to a greater extent ?

• A. $H_{2}O$
• B. $C{H}_{3}OH$
• C. Both A and B
• D. None of these

Answer 1

Answer: (A)

$H_{2}O$

Non-polar solutes do not dissolve in polar solvents like water because they are unable to compete with the strong attraction that the polar solvent molecules have for each other. Similarly, polar compounds cannot dissolve in non-polar solvents.

Hence, $Mg{Cl}_2$ can be dissolved in water due to its polar nature.
