Question

what happens when dilute sulphuric acid is poured on on a copper plate​

Answer 1

Answer: (a) When dilute sulphuric acid is poured on a copper plate, no reaction takes place due to less reactivity of copper. (b) When iron nails are placed in a copper sulphate solution, the blue colour of the sopper sulphate solution changes to green, due to the displacement of copper in copper sulphate by iron.

Answer 2

Answer:

Copper does not react with dilute sulphuric acid. So, no reaction will take place when diluting sulphuric acid is poured onto a copper plate. When iron nails are placed in a copper sulfate solution, iron displaces copper to form iron sulfate. Slowly, the blue color of the copper sulfate solution turns into green.
