Question

Word equation for iron nails are placed in copper sulphate solution

Answer 1

HEY THERE!

Theory: The element placed higher in the reactivity series can displace other metal from its salt solution.

Iron is above copper in the reactivity series, so iron is more reactive than copper, so iron will displace copper from copper sulphate solution.

Chemical equation: CuSO₄ + Fe ----> FeSO₄ + Cu

Word equation: Copper sulphate + Iron ----> Iron sulphate + Copper

Observation: Blue solution (copper sulphate) turns green (iron sulphate) and a reddish precipitate is obtained (copper).

Thanks!

Answer 2

Answer:

This reaction is called displacement reaction in which the reactive element Iron, Fe has displaced less reactive Copper from its solution, The chemical equation can be written as: Fe+CuSO4→Cu+FeSO4.
