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 ...

While there are a variety of other variables and protocols to be followed to ensure our food supply remains safe, a basic understanding of pH and how it is measured is crucial to food production.

pH meters are an essential part of many laboratories. pH can affect microbial growth and chemical reactions, pH meters must be calibrated regularly. pH meters consist of either distinct reference and ...
