Question

Zn + 2 HCl → ZnCl2 + H2 in this reaction i want reducing agent and oxidizing agent

Answer 1

In the reaction: Zn + 2HCl ⇒ ZnCl2  + H2 ↑ 

The reducing agent = Zinc(Zn)
The oxidising agent = H2↑

Answer 2

Answer: Reducing agent: Zn

Oxidizing agent : $HCl$

Explanation: I) Oxidation reaction : When there is an increase in oxidation state number.

$Zn\rightarrow Zn^{2+}+2e^-$

Reduction reaction : when there is a decrease in oxidation state number.

$2H^{+}+2e^-\rightarrow H_2$

Zinc metal has undergone oxidation, as its oxidation state is changing from 0 to 2+. Zinc metal is getting converted into zinc ions.

$H^+$ ions has undergone reduction, as its oxidation state is changing from +1 to 0. Copper ions are getting converted into copper metal.

$Zn$ is a reducing agent.

The chemical agent which itself get oxidized and reduce others is called reducing agent.

$HCl$ is an oxidizing agent.

The chemical agent which itself get reduced and oxidize others is called oxidizing agent.
