Question

What type of reaction is $Zn+CuC{{l}_{2}}\to Cu+ZnC{{l}_{2}}$ .

Answer 1

The reaction in which both oxidation (loss of electrons) and reduction (gain of electrons) are going to occur then the chemical reaction is called redox reaction. One element is going to accept the electrons and the other element will donate electrons.

Complete answer:
- In the question it is given to find the type of the given chemical reaction.
- The given chemical reaction is as follows.
$Zn+CuC{{l}_{2}}\to Cu+ZnC{{l}_{2}}$
- In the above chemical reaction zinc is going to convert into zinc chloride and cuprous chloride is going to convert into copper.
- The zinc before the chemical reaction has an oxidation state of ‘zero’ and after the chemical reaction the oxidation state of the zinc in $ZnC{{l}_{2}}$ is ‘+2’.
- Now coming to the oxidation state of the copper. The oxidation state of the copper in cuprous chloride (reactant side ) is ‘+2’and the oxidation state of the copper in product side is ‘zero’.
- Means in the given chemical reaction zinc is undergoing oxidation (loses electrons) and the copper is going to accept the electrons.
- Therefore in the given chemical reaction both oxidation and reduction is going to occur.
- So, the given chemical reaction is an example for redox chemical reaction.

Note:
In the given chemical reaction copper in the cuprous chloride is replaced with zinc and formed zinc chloride as the product. Means the given chemical reaction is an example for displacement chemical reaction.
