Caption: pH measurement. Electrometrical measurement of the pH of a solution of methanoic acid. The pH of a solution is a measure of the amount of free hydrogen ions present. This indicates acidity and alkalinity. The more free ions present, the more acidic the solution is said to be. pH is measured on an inverse scale: the smaller the number, the more acidic the solution. Here, the pH meter is showing 2.66, indicating quite a strong acid. The scale runs from 0-14, with pure water considered neutral at pH 7. Methanoic acid (formerly called formic acid) is a simple organic acid, and is present in ant bites.
