Question

Difference between polarography and potentiometry method

Answer 1

Potentiometry generally refers to all the analytical methods, based on the measurement of electrochemistry potential of a galvanic cell in the ‘absence of current’ state..
Polarography is a type of voltammetry where the working electrode is a dropping mercury electrode or a static mercury drop electrode, which are useful for their wide cathodic ranges and renewable surfaces. It was invented in 1922 by Czech chemist Jaroslav Heyrovský, for which he won the Nobel prize in 1959...
