The pH scale is a logarithmic scale used to measure acidity. The pH scale measures how basic or acidic a substance is, and it ranges from 0 to 14. On the pH scale, a pH of 7 is neutral, less than 7 is acidic and higher t... More »

The pH scale is a measure of how acidic or basic a liquid substance is. The pH is calculated as a negative logarithmic function of the concentration of hydrogen ions, which are acidic by nature. A high concentration of h... More »

The pH of a solution measures the amount of hydrogen ions that are in a solution. The term "pH" literally means "the power of hydrogen." The pH of a substance tells how acidic or basic a substance is. More »

Potential hydrogen, or pH, is the measure of the acidity or alkalinity of an aqueous solution. A solution is acidic if its pH is less than 7. If its pH is greater than 7, the solution is basic or alkaline. More »
