Titration using potassium manganate (VII) and acidified ethanedioate solution. At the start of the titration, the deep pink colour of the potassium manganate (VII) solution takes some time to disappear as Mn7+ ions are reduced to Mn2+ ions. See images C030/3776 and C030/3777 for the continuation of the reaction. | |
