What Is a PH Scale and How Does It Work?

Answer

A pH scale is a measure of the amount of acidity or alkalinity of a solution and ranges from 0 to 14. It works by indicating the intensity of acidic or alkaline components so that the numbers below 7.0 indicate acidity while the numbers greater than 7.0 indicate alkalinity. The midpoint of 7.0 on the pH scale represents neutrality.
