Why is acidic medium required for the oxidising action of potassium dicromate?t
Dear Student,
The dichromate has to be reduced to half reaction for acting as oxidising agent , for performance of half reaction are influenced by acidic medium by lowering pH to less than 7 from its neutral state and its reaction scheme is shown below as where H+ acts as reactant.
