WebpH is a measurement of the acidity or alkalinity of a solution. It provides a value on a scale from 0 to 14 where 7 is neutral, less than 7 is acidic, and greater than 7 is alkaline (or basic). The closer you move towards 0, the more a solution is acidic, and the closer you move to 14, the more a solution is alkaline.
