Question

Balance the following skeleton reaction and identify the oxidizing and reducing agents: H2S(g) + NO3 ---->’ S8(s) + NO(g) [acidic] Include the states for each reactant and product in the balanced chemical equation. Do not include the states when identifying the oxidizing and reducing agents.

Answer 1

Answer : Oxidizing agent is $NO^-_3$ and Reducing agent is $H_2S$

Explanation :

The given unbalanced redox reaction is,

$H_2S(g)+NO^-_3(aq)\rightarrow S_8(s)+NO(g)$

In acidic medium, the balanced redox reaction is,

$24H_2S(g)+6NO^-_3(aq)16H^+(aq)\rightarrow 3S_8(s)+16NO(g)32H_2O(l)$

Oxidizing agent : Oxidizing agents are those agent which oxidizes other substance and itself get reduced.

Reducing agent : Reducing agents are those agent which reduces other substance and itself get oxidized.

In this redox reaction, $NO^-_3$ is an oxidizing agent and $H_2S$ is a reducing agent.

The redox reaction is also shown below.

Answer 2

According to the given reaction, H₂S is a reducing agent and NO₃⁻ is an oxidizing agent.

What is reducing and oxidizing reagents?

Reducing agents are those agents which itself gets oxidized to help in the reduction of another reagent, and oxidizing agents are those which itself gets reduced to help in the oxidation of another reagent.

In acidic medium chemical reaction will be repesented as:
24H₂S(g) + 6NO₃⁻(aq) + 16H⁺(aq) → 3S₈(s) + 16NO(g) + 32H₂O(l)

In the above reaction-

• H₂S is a reducing agent because it gets oxidized itself.
• NO₃⁻ is an oxidizing agent because it gets reduced itself.

Hence H₂S is a reducing agent and NO₃⁻ is an oxidizing agent.
