pH Drops

The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity of the solution. The letters pH stand for “power of hydrogen” and the numerical value is defined as the negative base 10 logarithm of the molar concentration of hydrogen ions. pH drops are the simplest way to check pH. Just put a few drops of the reagent in a small sample of water and watch the color change. Then match the color with the included pH comparison scale. ***NOT FOR CONSUMPTION***
