Question

In the reaction PbS (s)+4H2O2(aq) →PbSO4(s)+ 4H2O , which is oxidizing agent and which is reducing agent?
pls ans the ques!!

Answer 1

Answer:

PbS is reducing agent....and H2O2 is oxidising agent

Answer 2

In the reaction $PbS (s) + 4H_2O_2(aq) -- > PbSO_4(s) + 4H_2O$ , $H_2O_2$ is an oxidizing agent and Pbs is a reducing agent.

Here, PbS has gained oxygen and $H_2O_2$ has given oxygen.

Substance oxidized is PbS; Substance reduced is $H_2O_2$.

Hence, the reducing agent is PbS, and the oxidizing agent is $H_2O_2$.

Explanation:

Oxidation-reduction or redox reaction :

• An oxidation-reduction or redox reaction is a reaction in which oxidation and reduction take place simultaneously.

• In redox reactions, the oxidizing agent is reduced, and the reducing agent is oxidized.

Oxidizing and Reducing agent:

Oxidizing agent :

Oxidizing agent is a substance which causes the addition of oxygen or the removal of hydrogen from other substances.

Reducing agent :

Reducing agent is a substance that causes the addition of hydrogen (H) or removal of oxygen (O) from other substances is called a reducing agent.
