Question

write a chemical equation for the reaction taking place in the test tube how does the colour of solution change what is change in colour of iron nail​

Answer 1

Answer:

when Iron nail (Ferrum) is dipped in copper sulphate (CuSO4) there takes reaction between them and coppersulphate change its colour from blue to light green. The formula for this reaction is:Fe:CuSO4--FeSO4+CuSO4--FeSO4+CuSO4.

Here FeSO4 is more reactive than CuSO4

Answer 2

When iron nail is dipped in copper sulphate solution there takes reaction between them and copper sulphate solution changes its colour from blue to light green.

Equation :- Fe+CuSo4→FeSo4+Cu.

I hope it will be help you!!!
