Understanding the nature of pH has bedeviled beginning (and not-so-beginning) chemistry students for nearly as long as chemistry has had students. It all seems so arbitrary, being the base-10 log of ...

pHe is a significant parameter for decreasing the risk of failing motors. It indicates the acid strength of ethanol and alcohol fuels. Determination of pHe of a denatured blend of ethanol utilizing a ...

A pH meter measures a pH or the acidity/alkalinity of substances. Most pH meters rely on a glass electrode that measures the number of hydrogen ions in the solution. Usually, pH meters need to be ...
