Question

What will happen when dilute sulphuric acid is poured on a copper plate​

Answer 1

Answer:

H2SO4+Cu-- CuSO4 + H2

Explanation:

Due to above displacement reaction colour of Cu changes to blue from black

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.
