Question

balance redox reaction:- No3^- +So2=So4^2-+No2​

Answer 1

Answer:

2NO3^- + SO2 — SO4^2- + 2NO2

Answer 2

Answer:

The balanced redox reaction:

NO₃⁻ + SO₂ → SO₄²⁻ + H⁺ + NO₂

Explanation:

There are two common techniques for balancing the redox reactions, the oxidation number change method and the ion-electron method (also known as the half-reaction method).

Balancing by oxidation number change method,

1. Write down the unbalanced equation in ionic form.
2. The process is separated into half-reactions, oxidation, and reduction reactions.
3. Balancing the atoms in each half-reaction includes the balancing of other atoms except hydrogen and oxygen and then Balancing the charge and then Balancing the oxygen atoms.
4. Making the electron gain equivalent to electron lost. The electrons lost in the oxidation half-reaction must be equal to the electrons gained in the half-reaction.
5. Add the half-reactions together and the redox reaction is balanced.

Using the above method, the reaction can be balanced.

Hence, the balanced redox reaction is NO₃⁻ + SO₂ → SO₄²⁻ + H⁺ + NO₂.
