Question

consider the reaction
2hbr + cl2 ------- 2hcl + bl2
Identify the substance
1) getting reduced
2) getting oxidised
3) acting as reducing agent
4) acting as oxidising agent

Answer 1

Answer:

1) Cl2 is reduced 2) Br negtive is oxidized 3) Hbr acting as rducing agent 4) Cl2 as oxidizing agent

Answer 2

(There is some mistake in the given reaction. The correct reaction can be given as $\[2HBr + C{l_2} \to 2HCl + B{r_2}\]$)

The substance

1) getting reduced - $\[C{l_2}\]$

2) getting oxidised - $\[HBr\]$

3) acting as reducing agent - $\[HBr\]$

4) acting as oxidising agent - $\[C{l_2}\]$

Explanation:

• When oxygen is added or hydrogen is removed from a compound, the process is called oxidation.
• When hydrogen is added or oxygen is removed from a compound, the process is called reduction.
• The reactant that reduces other compounds and itself gets oxidised is called a reducing agent.
• The reactant that oxidises other compounds and itself gets reduced is called an oxidising agent.
• In the given reaction, hydrogen is being removed from HBr and it gets oxidised to $\[B{r_2}\]$.
• At the same time, hydrogen is being added to $\[C{l_2}\]$ and it gets reduced to HCl.
• Therefore, HBr acts as a reducing agent while $\[C{l_2}\]$ acts as a reducing agent.
