Write a balanced half-reaction for the oxidation of gaseous nitric oxide to aqueous nitrous acid in acidic aqueous solution. be sure to add physical state symbols where appropriate.

Explanation:

Reaction for oxidation of gaseous nitric oxide to aqueous nitrous acid is as follows.

By adding water, we will balance the oxygen atoms on both the sides as follows.

Now, we will balance the hydrogen atoms by adding ions as follows.

Now, we will add ions on both the sides in order to neutralize ions.

      ..... (1)

We will combine the and ions in order to form water in equation (1) and cancelling the common terms as follows.

Now, we will balance the charge on both the sides as follows.

Thus, we can conclude that the balanced half-reaction equation is as follows.
