Question

${NH}_4^{+}$ ion an aqueous solution will behave as:

• A. A base
• B. An acid
• C. Both acid and base
• D. Neutral

Answer 1

The correct option is B An acid

According to Lewis acid-base theory, a Lewis acid will donate its proton $H^{+}$ and Lewis base will accept proton $H^{+}.$

When ${N{H}_4}^{+}$ is reacted with a base, it will release its proton $\left(H^{+}\right)$ by lewis acid-base theory,
