Question

Give reason why cuso4 solution cannot be stored in a zinc vessel

Answer 1

Because Zn is more reactive than copper.
S.R.P value of Zn is less means it has tendency to oxidisize & it behave like reducing agent.So,it displace copper from its solution & form ZnSo4 .So to prevent this reaction to occur CuSo4 soln. can't be stored in a zinc vessel.
Hope it may help you

Answer 2

Hi. CuSO₄ can't be stored in zinc vessel because zinc is more reactive than copper and a displacement reaction will occur between them and zinc sulphate will be formed along with copper as another product.

Reactivity series of metals is where metals are arranged in their order of reactivity from most reactive at the top to least reactive at the bottom.

Since, zinc is higher in the reactivity series than copper, it will replace copper from copper sulphate solution to form zinc sulphate solution and, copper will accumulate at the bottom of the the test tube.

The reaction that will take place in the displacement reaction is as follows:

                    Zn + CuSO₄ → ZnSO₄ + Cu

Hope it helps.
