Question

give the chemical equation in which
colour change of occurs​

Answer 1

Answer:

chemical reaction between copper sulphate and iron

Explanation:

when iron reacts with copper sulphate displacement reaction occurs.. iron displaces copper from its salt solution as iron is more reactive than copper.

The blue coloured solution of copper sulphate changes to green coloured solution of iron sulphate

Answer 2

Answer:

Chemical reaction between ferrous sulphate and zinc metal.

Explanation:

• Colour of ferrous sulphate solution before reaction :- Light Green
• Colour of zinc sulphate formed after the reaction :-  Colourless
• When zinc metal is added to a solution of ferrous sulhate a colourless solution of zinc sulphate is formed.

Reaction :

          FeSO₄  +   Zn =  ZnSO₄ + Fe

Observation :

The light green solution of ferrous sulphate after the reaction turns colourless.

Conclusion :

Zinc displace Iron from its sulphate solution this means zinc is more reactive than iron.

Thank You
