Question

if we take iron sulphate solution and add copper fillings what will happen and why​

Answer 1

Answer: So the iron nail will get a copper coating and the blue copper sulphate solution will start to change to green ferrous sulphate solution. the iron (2+) will go in the solution and Cu(2+) will get deposited on d iron nail. so it will turn reddish-brown and the colour of the solution will also change from blue to green.

Explanation:Hope it helps

Answer 2

Answer:

When an iron nail immersed in the solution of copper sulphate than iron displaces copper from the solution of copper sulphate because iron is more reactive than copper. Therefore copper sulphate solution colour changes from blue to pale green.
