Answers

Answered by yogeshdhande07

Answer:

Solution:

(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.

Copper + Conc. â†’ Copper + Hydrogen

Sulphuric Sulphate gas

Acid

(b) Iron is more reactive than copper. 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.

Iron + Copper â†’ Iron + Copper

Sulfate
