Question

What is the change in electrons for sulfur in the following reaction?

S + NO3 - -> SO2 + NO

A. Lose 4 electrons
B. Lose 2 electrons
C. Gain 4 electrons
D. Gain 2 electrons

Answer 1

Answer:

A. Lose 4 electrons

Explanation:

The reaction equation is given as:

                  S + NO₃ → SO₂ + NO        

The half equation of the reaction for S:

                   S → SO₂

          For S to go into SO₂,

we move from an oxidation state of 0 to +4,

Finding the oxidation state of S in SO₂

                             a + (-2 x 2) = 0

                             a - 4 = 0

                              a = 4

This is a loss of 4 electrons
