(a) dilute sulphuric acid is poured on a copper plate? Write word equation of the reaction involved.
(b) iron nails are placed in copper sulphate solution? Write word equation of the reaction involved.​

Answer 1

Answer:

Answer : (a) When dilute sulphuric acid is poured on a copper plate, bubbles of hydrogen gas appear on the surface of plate. (b)When we add iron in the copper sulphate solution. The blue colour of copper sulphate fades and there is deposition of copper on the iron nail.

Answer 2

Answer:

1. cu + H2so4 - no rx

Since cu is less reactive than hydrogen

2.fe +cuso4 - feso4 +cu
