Question

Which have he following ion have highest ionic density?

• A. $H^{+}$
• B. $L{i}^{+}$
• C. $N{a}^{+}$
• D. $K^{+}$

Answer 1

The correct option is A $H^{+}$

ionic density means no. of ions present in per unit of volume.

as we know that the size of the H+ ion is less than Li+, Na+, K+.

Thus it will have maximum no. of ions in per unit volume.

Hence, H+ will have maximum ionic density among the options.

Therefore, the option is A.
