The ph of a solution is 7. which best describes the solution?
the solution has more hydrogen ions than hydroxide ions.
the solution has fewer hydrogen ions than hand soap.
the solution has the same number of hydrogen ions as apple juice.
the solution has the same number of hydrogen ions and hydroxide ions.

Option (d) is the correct answer.

Explanation:

A solution with a pH 7 means that the solution is neutral.

For example, the pH of pure water is 7.

Therefore, the statement solution has the same number of hydrogen ions and hydroxide ions is correct.

Solutions which have pH less than 7 are acidic in nature, that is, they have more number of hydrogen ions.

Solutions which have pH more than 7 are basic in nature, that is, they have more number of hydroxide ions.
