This text introduces potentiometry, a branch of electrochemistry, explaining how potential differences arise in systems, both externally applied and spontaneously generated. It details Alessandro Volta's discovery of electricity generation through chemical reactions, specifically using a metal rod in water. The example of a zinc rod in water illustrates the development of a negative charge on the rod and a positive charge in the solution due to the release of zinc ions and electrons, eventually reaching an equilibrium state.

This document explores the principles of potentiometry and electrochemistry, detailing how potential differences arise in chemical systems. It covers the historical discoveries of Alessandro Volta, the behavior of metal electrodes in solutions, the concept of normal potentials and the electrochemical series, metal displacement reactions, electrolysis, electrical cells (galvanic and electrolytic), the Nernst equation, and the workings of specific batteries like the Leclanché cell and the lead-acid battery.
