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 ...

Systems pH control systems are known by their extreme rangeability and sensitivity, but contact between the measurement electrodes and hostile fluids can cause issues. Case studies of representative ...

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 ...

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 ...

Ensuring the purity of boiler feedwater demands the use of highly capable pH electrodes. Power plant cycle chemistry guidelines and standards specify narrow ranges of pH to minimize corrosion of ...

Throughout human history, discerning sour from bitter tastes in both liquid and solid foods has been essential. For instance, vinegar and lemon juice are widely identified as sour, whereas soapy water ...
