Explain how to carry out a redox titration involving Manganate VII (MnO4-). |
Add a known volume of Manganate ions /MnO4- (Purple)in aqueous potassium manganate to a known volume of reducing agents i.e. Fe2+. Gradually add untill all the reducing agent is used up causing a colour change i.e. colourless to purple. This is the end point of the reaction. |
