Question

why colour is dissipated when copper suplate react with zinc
​

Answer 1

Hey mate

Here's your answer

If we dip a zinc strip into a copper sulfate solution, as shown opposite, the zinc will be eaten away, a spongy layer of metallic copper will plate out on the zinc strip, and the deep blue color of copper sulfate will gradually fade. (Zinc sulfate, which is formed, is colorless.)

Answer 2

Answer:

In this reaction,

the less reactive copper from copper solution is displaced on more reactive zinc.
