Question

which is used to measure the concentration of hydrogen ions​

Answer 1

Answer:

The Electrometric Method for determining the Hydrogen Ion Concentration, or pH value, of a solution consists essentially in measuring the difference in potential between two special electrodes in contact with, the solution by means of a null potentiometer, the electrodes and solution comprising an electric cell, called a concentration cell or chain, in which one electrode develops a potential according to the Hydrogen Ion Concentration of the solution, while the other electrode has a constant, definite potential independent of the Hydrogen
