INFOGRAPHIC 2.9 SOLUTIONS HAVE A CHARACTERISTIC pH
The pH of a solution is a measure of the concentration of hydrogen ions (H+) in it. Solutions with a low concentration of H+ ions have a basic pH (greater than pH 7). Solutions with a high concentration of H+ ions have an acidic pH (a pH of less than 7). Both acids and bases can be damaging because they are highly reactive with other substances. A neutral solution has a pH of 7.
