WebAnswer: The orange color of dichromate is due to charge (electron) transfer from O2- ligands to the empty d orbitals of the central metal Cr6+, i.e. LMCT. This electronic … WebAboutTranscript. A 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.
