Question

Which has least molar solubility in $H_{2}O$?

• A. $LiCl$
• B. $NaCl$
• C. $KCl$
• D. $CsCl$

Answer 1

The correct option is A $LiCl$

As we move down the group the solubility of chlorides of alkali metals increases as the ionic nature of the compound increases. So, $LiCl$ has the least molar solubility as it is a weak ionic compound.

Hence option A is correct.
