Question

zinc rod is left for nearly 20 minutes in a copper sulphate solution what change would you observe in zinc rod

Answer 1

Heya.....☺

Here's ur ans.⤵

===============

◾ Zinc is more reactive than copper. ,therefore it displaces copper from copper sulphate solution and forms zinc sulphate .

✡ Zn + CuSO4 --- ZnSO4 + Cu ✡

↪ It's single displacement reaction.

↪ The blue colour of copertina sulphate will turn it brown zinc sulphate.


✌Hope it helps

Answer 2

Explanation:

The correct answer is-

Zinc is more reactive than copper. Due to this, it will undergo displacement reaction.

When zinc rod is placed in the copper sulphate solution, it will displace copper from its solution and the brownish copper color will start depositng over the zinc rod. As a result, copper sulphate solution start becoming decolorized and zinc sulphate solution starts forming.
