Question

For the given reactions, classify the reactants as the reducing agent, oxidizing agent, or neither. cl2 + h2 → 2hcl 2n2 + o2 → 2n2o

Answer 1

Answer:

a) $Cl_{2}$ is an oxidizing agent and $H_{2}$ is a reducing agent.

b)$O_{2}$ is an oxidizing agent and $N_{2}$ is a reducing agent.

Explanation:

In a given reaction, a reducing agent is one which has a tendency to loose electrons thereby getting oxidized. In contrast, an oxidizing agent is one which has a tendency to accept electrons thereby getting reduced.

a) The given reaction is:

$Cl_{2}+ H_{2}\rightarrow 2HCl$

The reactants are $Cl_{2}$ and $H_{2}$ each with an oxidation state (OS) = 0. In the product, $HCl$, the OS of H = +1 and that of Cl =- 1

Since the OS of Cl has changed from 0 to -1, it has got reduced hence $Cl_{2}$ is an oxidizing agent. Similarly, since the OS of H has changed from 0 to +1, it has got oxidized hence $H_{2}$ is a reducing agent.

b) The given reaction is:

$2N_{2}+ O_{2}\rightarrow 2N_{2}O$

The reactants are $N_{2}$ and $O_{2}$ each with an oxidation state (OS) = 0. In the product, $N_{2}O$, the OS of N = +1 and that of O =- 2

Since the OS of O has changed from 0 to -2, it has got reduced hence $O_{2}$ is an oxidizing agent. Similarly, since the OS of N has changed from 0 to +1, it has got oxidized hence $N_{2}$ is a reducing agent.

Answer 2

The reactants in the reaction which are reducing reagents are H₂ and N₂, and oxidizing reagents Cl₂ & O₂.

What are reducing and oxidizing reagents?

Reducing agents are those reagents which gets itself oxidised to loose electron and oxidizing agents are those reagents which itself gets reduced by gaining electron.

• Cl₂ + H₂ → 2HCl

In the above reaction oxidation state of chlorine atom changes from 0 to -1 from reactant side to product side and acts as an oxidizing agent, and of hydrogen atom changes from 0 to +1 & acts as a reducing reagent.

• 2N₂ + O₂ → 2N₂O

In the above reaction oxidation state of oxygen atom changes from 0 to -2 from reactant side to product side and acts as an oxidizing agent, and of nitrogen atom changes from 0 to +1 & acts as a reducing reagent.

Hence chlorine and oxygen atoms are oxidizing agent & oxygen and nitrogen atoms are reducing reagent.
