Question

what happens when dilute H2 S o4 is poured on copper plate

Answer 1

CuSO4 will be produced and hydrogen gas will liberate

Answer 2

Answer: Copper does not react with dilute sulphuric acid. So, no reaction takes place when dilute sulphuric acid is poured on a copper plate. But when concentrated sulphuric acid is poured over copper plate, effervescence is observed. This happens because of formation of hydrogen gas.
