pH electrodes are used in analytical chemistry to measure potential of hydrogen ions. pH is the negative logarithm of the hydrogen ion activity in a solution. The pH value of a solution is dependent on the ratio of concentrations of the hydrogen ion [H+] and the hydroxyl ion [OH-] in a particular solution. pH electrodes are widely used in process applications and laboratory measurements owing to dependency of many chemical processes on pH. There is a significant difference between pH ... Read more
