Write a balanced half-reaction for the reduction of aqueous nitrous acid hno2 to gaseous nitric oxide no in basic aqueous solution. be sure to add physical state symbols where appropriate.

The unbalanced chemical reaction of the transformation of aqueous nitrous acid to gaseous nitric oxide is as follows:

HNO₂ (aq) → NO (g)

In the above-mentioned equation, balancing is done by adding a OH,

HNO₂ (aq) → NO (g) + OH⁻ (aq)

Now, the balancing of the charge is done by adding the electrons on the left side,

HNO₂ (aq) + e⁻ → NO (g) + OH⁻ (aq)

Therefore, the balanced half-reaction in the basic medium is as follows:

HNO₂ (aq) + e⁻ = NO (g) + OH⁻ (aq)
