Question

What happens when dilute sulphuric acid is poured on a copper plate?
Write word equation of the reaction involved.

Answer 1

Dilute sulphuric acid does not react with copper. Since copper is less reactive than hydrogen, it cannot replace the hydrogen from dilute sulphuric acid. Thus, no reaction occurs in this case.
Dil. Sulphuric acid + Copper $\to$ No reaction
However, concentrated sulphuric acid can oxidise copper when heated.
