Answer 1

a) the colour change- from blue to green.

b)yes. iron being more reactive than copper displaces it.As most reactive species displace the least reactive ones.

c) displacement reaction:

Fe+CuSO4 gives FeSO4 +Cu

Answer 2

Heya !

Here's your answer !!!


_________________________

( a ) The blue colour of copper sulphate solution changes to light green colour and reddish deposit of copper is foemed on the surface of iron. The green colour of the solution is due to the formation of ferrous sulphate.

( b ) Yes, it is a chemical change in which a more acrive metal ( iron ) displaces less active metal ( copper ) from its salt solution ( copper solution ). This reaction is called chemical displacement reaction and is irreversible.

( c ) The chemical reaction can be represented as :

CuSO4 ( sol. ) + Fe ----------> FeSO4 + Cu

Copper sulphate + Iron -------------->

Iron sulphate Solution + Copper
