Answer 1

Question:

Why does colour of iron nail change when we dip it in copper sulphate solution with example?

Answer:

◆ When we add iron nail in Copper Sulphate Solution.

Equation: CuSO4 + Fe ---- FeSO4 + Cu

CuSO4 = Copper Sulphate Solution

Fe = Iron nail

FeSO4 = Iron Sulphate

Cu = Copper

◆ It is a Displacement reaction.

◆ Displacement Reaction: The reaction in which high reactive metal displace the less reactive metal is called DISPLACEMENT REACTION.

◆ In these above equation Iron is high reactive metal than the copper because Iron ( Fe ) will displace the Copper ( Cu ).
