In a particular redox reaction, cr is oxidized to cro42- and ag+ is reduced to ag. complete and balance the equation for this reaction in acidic solution.

The complete and balance the equation for this reaction in acidic solution is given by:

Explanation:

Oxidation reaction of chromium to chromate in acidic medium:

Add 4 molecules of water on the left hand side to balance the oxygen:

Now balance hydrogen atoms by adding hydrogen ions on opposite to the side where water molecule are present .

....[1]

In last, to balance the charge on the both sides add electrons to sides where positive charge is more.

Reduction reaction of silver ions to silver in acidic medium:

..[2]

By [1] + 6 × [2] , we will get the balance equation for this reaction in acidic solution:
