My observations ...
When an iron nail is left in a co[[er sulphate solution, there is a formation of iron sulphate and copper.This leads to a chemical change.

When iron nails were put in solution of copper sulphate it forms iron sulphate copper because copper is ore reactive than iron

# data[].attributes.body
When the iron nails were put in solution of copper sulphate, the formation of iron sulphate, it forms iron sulphate and copper took place because iron is more reactive than copper.

A few things I observed were -

When iron nails are put into a solution of copper sulphate, it forms iron sulphate and copper, because iron is more reactive than copper.

Another observation was that when bits of zinc are mixed with a solution of copper sulphate, it forms zinc sulphate and copper.

Sulphuir doesn't react with acids

when the iron nail was put inside the copper sulphate solution, the solution turns into iron sulphate vecause iron is more reactive than copper.
