Question

what happens when zn strip is dipped in CU S o4 solution

Answer 1

CuSO4 solution has a blue colour while ZnSO4 solution is colourless. ... On addition of Zinc granules/strip , displacement reaction will take place and hence the formation of zinc sulphate will occur. The colour will disappear and heat will be released(exothermic reaction).

Answer 2

Copper sulphate is blue in color, when zinc strip is dipped solution displacement reaction takes place because zinc is more reactive than Copper so zinc displace Copper from its sulphate solution and the solution became colorless as it now zinc sulphate solution and Copper stick on the zinc strip.

Hope this will help you..... ✌
