One form of this lab technique induces coagulation or flocculation of colloids nearing the isoelectric point, at which their zeta potential is approximately zero. Another variety, which may use the chelating agent EDTA, is the complexometric type. Potentiometers determine the endpoint of this technique's "redox" types, and their namesake graphs feature a point of inflection called the equivalence point. For 10 points, name this lab technique often done using an indicator to determine an unknown pH, which uses a buret to drip precise amounts of reactant into a solution until something drastic occurs.
