A Solution with a PH of 9 Has More Hydrogen

Question

A solution with a pH of 9 has more hydrogen ions than hydroxide ions.

Accepted Answer

A solution with a pH of 9 is considered basic and has more hydroxide ions than hydrogen ions. In fact, a solution with a pH of 9 has 1x10^-5 moles of hydrogen ions per liter and 1x10^-5 moles of hydroxide ions per liter, making it neutral. Any solution with a pH greater than 7 is considered basic and has more hydroxide ions than hydrogen ions.
