This document discusses amperometric titration, which is a quantitative analysis technique where the equivalence point of a titration is determined by measuring the electric current produced by the titration reaction. It involves using a working electrode to apply an electrolytic potential to a solution containing an analyte and a conductive buffer. As a titrant is added that reacts with the analyte, the concentration and resulting current are measured. A plot of current vs titrant volume produces a straight line, with the equivalence point indicated by a change in slope when excess titrant is reduced at the electrode. Amperometric titrations offer selectivity advantages over other techniques.
