Potentiometric titration | Experimental Method and Applications

potentiometric titration

Potentiometric titration is a method of chemical analysis. This technqiue relies on the measurement of electromotive force (EMF) of a solution using a set of indicator and reference electrodes. The potential or EMF of a solution depends on the nature and concentration of the ions of the test substance. The EMF or potential is measured […]
