WebbAn oxidizing titrant such as MnO 4 –, Ce 4 +, Cr 2 O 7 2–, and I 3 –, is used when the titrand is in a reduced state. If the titrand is in an oxidized state, we can first reduce it with an auxiliary reducing agent and then complete the titration using an oxidizing titrant. Alternatively, we can titrate it using a reducing titrant.
