Question

A salt that forms neutral aqueous solutions is:

• A. $S{O}_2$
• B. $Ba(OH{)}_2$
• C. $KCl$
• D. $Fe(N{O}_3{)}_3$
• E. $Li{C}_2{H}_3{O}_2$

Answer 1

The correct option is C $KCl$

Option $C$ is the correct answer.

$KCl$ will form a neutral aqueous solution. The two ions present here are $K^{+}$ and ${Cl}^{-}$. $K^{+}$ is obtained from a strong base $KOH$ while ${Cl}^{-}$ is obtained from a strong acid $HCl$. Thus the effect of these two strong ions counteract each other. And the aqueous solution is neutral in nature.
