Question

An acid solution contains more... ions than... ions.

Answer 1

Answer: An acid contains more hydrogen ions than hydroxide ions.

Explanation:

An acid is defined as the chemical compound which has a high concentration of hydrogen ions. They are considered as proton donors and they act as proton $(H^+)$ donors when they have high concentration of hydrogen ions.

A base is defined as a chemical substance which has high concentration of hydroxide ions. They are considered as proton acceptors and they act as proton $(H^+)$ acceptors when they have low concentration of hydrogen ions.

Hence, an acid is contains more hydrogen ions than hydroxide ions.
