PH meter, electric device used to measure hydrogen-ion activity (acidity or alkalinity) in solution. ... The pH-responsive electrode is usually glass, and the reference is usually a silver–silver chloride electrode, although a mercury–mercurous chloride (calomel) electrode is sometimes used.
What are pH electrodes used for?
pH electrodes are analytical sensors for measuring potential of hydrogen (pH), the negative logarithm of the hydrogen ion activity in solution. The pH value of a substance is directly related to the ratio of the hydrogen ion [H+] and the hydroxyl ion [OH-] concentrations.
What is reference electrode in pH meter?
A reference electrode is used in combination with a glass electrode so that the difference in potential generated between it and the glass electrode can be measured. It also indicates a known potential irrespective of the pH of the solution.
