Why does the colour of copper sulphate solution change when an iron nail is kept immersed in it?

Posted by Sneha Shiny 4 years, 2 months ago

CBSE > Class 10 > Science

4 answers

Dhana Lakshmi S 4 years, 2 months ago

The colour of copper sulphate solution (CuSO4) changes from blue to green.Because here Iron is high reactive than copper,so it displaces Copper from Copper sulphate solution. Equation: CuSO4+Fe GIVES FeSO4+Cu.This is a displacement reaction

Sweet Snappy 4 years, 2 months ago

Because of displacement reaction... as Iron being more reactive than copper displaces copper and hence the colour changes from blue to green as the colour of FeSO4 is green HOPE IT HELPS YOU!! :)

Pankaj Kumar Patel 4 years, 2 months ago

It is displacement reaction.

Pankaj Kumar Patel 4 years, 2 months ago

When an iron nail immersed in the copper sulphate solution than the copper displaces in the copper solution because iron is more reactive than copper . Therefore the colour sulphate is changed
