Question

when iron rod is kept dipped in copper sulphate solution for sometime a brown coating is formed on the iron rod what change will be observed in the colour of the solution also write the chemical equation for the reaction​

Answer 1

$\huge \boxed{answer}$

◆ When Iron rod is kept dipped in a copper sulphate solution for sometime then iron sulphate solution and copper metal is formed.

$\boxed{explaination}$

◆ When it is placed, iron displaces copper sulphate solution. The deep blue colour of copper sulphate solution fades due to the formation of light green solution of iron sulphate.

A red - brown coating of copper metal is formed on the surface of iron metal ( or iron nail).

$\boxed{reaction}$

$cuso{4} \: + \: fe \: - > \: feso4 \: + \: cu$

Cuso4 –> Blue solution
Fe –> Grey
FeSo4 –> Greenish solution
Cu –> Red- brown
