This document discusses electrochemistry and polarography. It explains that polarography uses the technique of controlled-potential electrolysis to study electrochemical reactions through measurements of current versus voltage. Polarization curves generated from these measurements can be used to determine properties like the number of electrons transferred in a redox reaction. Polarography is commonly used to study reactions involving metal ions in solution and to detect various analytes based on their oxidation or reduction potentials.
