Solution

The correct option is C Both Assertion and Reason are correct and Reason is correct explanation of Assertion
1 equivalent of potassium dichromate contains one equivalent of potassium, one equivalent of chromium and one equivalent of oxygen. This is because one equivalent of potassium, one equivalent of chromium and one equivalent of oxygen react to form one equivalent of potassium dichromate.
