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.

1 answer

The solution has the same number of hydrogen ions and hydroxide ions.

A pH of 7 indicates that the solution is neutral, meaning the concentration of hydrogen ions (H⁺) is equal to the concentration of hydroxide ions (OH⁻).
