WebBack titration (BT) can be used as a time-saving alternative for measuring BN. The titration technique depends on the indication of the endpoint to determine the concentration of the analyte (in this case, the amount of basic constituents) within a sample. WebA redox titration is a titration in which the analyte and titrant react through an oxidation–reduction reaction. As in acid–base titrations, the endpoint of a redox titration is often detected using an indicator. Potassium permanganate (KMnO₄) is a popular titrant because it serves as its own indicator in acidic solution. Created by Jay. Sort by:
