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.

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.
