Question

see the pic and tell me the answer plzz
Ques- Take some copper sulphate in a beaker and add some water to it.

1. What is the colour of the solution so formed?
2. Now add a piece of iron to it and allow it to stand for few hours. What do you observe?
3. Why has the colour changed?
4. What conclusion do you draw?
5. Give a chemical equation for the reaction.​

Answer 1

Answer:

Explanation:1 . blue color

2. when we add iron nail into it's color changes

3. because iron nail displace copper from it's copper sulphate solution.

4. high reactive metals displace less reactive metals.

5. CuSO4 + Fe ----------> FeSO4 + Cu

Answer 2

Answer:

1. its blue as we have to make crystal of copper sulphate water solution

2. THE BLUE COLOUR OF THE SOLUTION FADES AND EVENTUALLY TURNS INTO LIGHT GREEN

ii. A BLACK COLOUR SUBSTANCE IS FORMED IN COPPER SULPHATE

3. WHEN AN IRON NAIL IS IMMERSED IN THE SOLUTION OF COPPER SULPHATE THAN THE IRON DISPLACES COPPER FROM THE SOLUTION OF THE COPPER SULPHATE BECAUSE IRON IS MORE REACTIVE THAN COPPER .THEREFORE COPPER SULPHATE COLOR CHANGES FROM BLUE TO PALE GREEN .

4. HIGH REACTIVE METAL DISPLACES LESS REACTIVE METAL

5.CUSO4+FE----->FESO4+CU
