Question

When dissolved in water, which of the following forms a molecular solution?

• A. $HC{l}_{\left(g\right)}$
• B. $NaN{O}_{3\left(s\right)}$
• C. $C{H}_{3}O{H}_{\left(l\right)}$
• D. $K_{2}S{O}_{4\left(s\right)}$

Answer 1

Answer: (C)

$C{H}_{3}O{H}_{\left(l\right)}$

$C{H}_{3}OH$ is a non-electrolyte. It does not dissociate into ions. Hence, it will dissolve in water to produce the molecular solution.

On the other hand, $HCl$, $NaN{O}_3$ and $K_{2}S{O}_4$ are electrolytes. They dissociate to form ions.
