Question

CUSO4+FE=CU+FESO4
इस विक्रिया मे ऑक्सीकरण और अवकरण दोनों का समीकरण लिखो​

Answer 1

Given equation: CuSO4 +Fe =Cu+FeSO4

ऑक्सीकरण means oxidation

अवकरण means reduction

Here,

The matter state of the above elements and compounds in the reaction is as follows:

Fe- solid

Cu- solid

CuSO4- aqueous solution

FeSO4- aqueous solution

When Iron nail (Fe) kept in Copper sulphate (CuSO4) there takes reaction between them. As Iron is more reactive tha Copper it can replace Copper from CuSO4.

Fe + CuSO4 =FeSO4 + Cu

CuSO4 is a oxidatizing agent so, it reduces to Cu(s).

FeSO4 is a reducing agent so, it oxidised to give Fe(s).

CuSO4 is in blue Colour and FeSO4 is in light green colour.

So, there will be change in the composition and colour of the solution (from blue to light green). And decomposition of Copper layer on surface of nail.
