The molarity of the Librium in the unknown has to be determined. Concept Introduction: Polarography is an electro analytical method in that composition of dilute electrolytic solution is studied. Here current-voltage curve is plotted. In this technique the voltage applied to a polarizable electrode is increased over a small range and the current changes throughout the solution are noted.
