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 [tex](H^+)[/tex] 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 [tex](H^+)[/tex] acceptors when they have low concentration of hydrogen ions.
Hence, an acid is contains more hydrogen ions than hydroxide ions.
