Answer:
(a) Copper does not react with dilute sulphuric acid. So, no reaction will take place when diluting sulphuric acid is poured onto a copper plate. But when concentrated sulphuric acid is poured onto a copper plate, effervescence is observed.
This reaction is called displacement reaction in which the reactive element Iron, Fe has displaced less reactive Copper from its solution, The chemical equation can be written as: Fe+CuSO4→Cu+FeSO4.
