Question

Student to copper sulphate solution in a beaker but iron nail it into and left it for half an hour write about the following what changes they observe in copper sulphate solution what changes they observe in in iron nail write complete chemical equation involved in it

Answer 1

Here's your answer :

Iron is higher than copper on the reactivity series, thus it will displace copper from the solution.

The evolution that takes place in the following reaction will be the following

Copper Sulphate + Iron = Iron Sulphate + Copper (deposits on the iron nail)

CuSo₄ + Fe = FeSo₄ + Cu

Answer 2

Answer:

WHEN IRON NAIL IS KEPT IN A COPPER SULPHATE SOLUTION THE COLOUR OF THE SOLUTION CHANGES FROM BLUE TO PALE GREEN

THIS COLOUR CHANGE IS BECAUSE DUE TO THE FORMATION OF IRON SULPHATE IN THE BEAKER

THE IRON BEING MORE REACTIVE THAT COPPER DISPLACES IT FROM ITS SALT SOLUTION AND FORMS IRON SULPHATE

ALSO ON THE IRON NAIL WE CAN SEE THE DEPOSITS OF A REDDISH - BROWN METAL CALLED COPPER

THE CHEMICAL EQUATION FOR THIS REACTION IS :-

Fe(s) + CuSO₄(aq) ----->FeSO₄(aq) + Cu(s)

(grey)   blue -------------> pale green    (reddish brown metal)
