Answer 1

Answer:

Given below :-

Explanation:

Material required- Iron nails, copper sulphate solution.

Process- Add about 10 ml of copper sulphate solution in a test tube and dip an iron nail tied to a thread in it. keep this as it is for 20-30 mins. later, after taking out the nail, you will observe that the nail has developed a reddish brown coating called rust.
