Question

wwrite any two observations which show that the iron is more reactive than copper​

Answer 1

Answer:

Explanation:

1)Take a solution of copper sulphate and put iron nails in it. The solution will turn light green and there will be copper coating on top of iron.

2) I don't know a second one sorry

Answer 2

Answer:

Dear Mate !

Explanation:

A)To prove that iron is more reactive than copper, the solution of copper sulfate is taken. Some iron nails are added to it. Later, it is observed that a brown coating is formed on the surface of iron and the color of copper sulfate solution has turned to light green from blue. This is due to high reactivity of iron which displaces the copper ions from its solution and forms ferrous sulfate solution.

B) Iron is high on the reactivity series while copper is present below it.So iron can displace copper easily from its salt solution by showing a change in the color of the solution.
