Question

In which solvent does NaCl have maximum solubility?

Answer 1

$\mathrm{NaCl}$ has maximum solubility in water.

1. The $\mathrm{NaCl}$ has maximum solubility in water (${\mathrm{H}}_2\mathrm{O}$) due to its polar character.
2. $\mathrm{NaCl}$ is a polar compound and water is also a polar compound.
3. Water is a polar molecule since it is formed using a strongly electronegative oxygen atom attached to a pair of hydrogen atoms and possesses a slightly negative charge on it.
4. According to solubility rule like dissolve like, polar compound dissolves in polar compounds.
5. Therefor $\mathrm{NaCl}$ is highly soluble in water as both are polar in nature.
