Answer:

Measuring acidity and alkalinity

It is a measure of the concentration of hydronium (H30+11OH) ionic bonds in a solution. The greater the concentration of hydronium ions, the lower the pH and the more acidic it is. Solutions with a pH of less than two are considered strong acids. Solutions with a pH of greater than 12 are considered strong bases.
