Which statement correctly describes pH values below 7?

pH is a measure of how acidic or basic a solution is, based on hydrogen ion concentration. Values below 7 indicate acidity because the solution has more hydrogen ions than neutral water. The scale is a negative log, so as [H+] increases, pH decreases. Neutral is 7, where [H+] and [OH−] are balanced. Basic (alkaline) solutions have pH above 7, with fewer hydrogen ions. So pH values below 7 correctly describe acidity.
