Formation of the relatively un-ionized HgCl2, thereby making a. predominant shift in the equilibrium so that the titrimetric reaction is. The electrodes are immersed in the solution to be titrated and the potential difference between the electrodes is measured. It can also be used to titrate samples that contain acid combinations.
