Question

When zinc is placed in ___________ solution , a reaction occurs causing

copper metal to deposit on the __________.

_________ removes _______ from the solution. This results in the

change of colour of the solution from _______ to _____________.



On the other hand, if you place a _________ strip in a solution of zinc

sulphate the reaction will not occur.

Thus,__________ is more reactive than________.​

Answer 1

Answer:

The standard reduction potential of zinc and copper are -0.76V and 0.34V. The more negative metal(Zinc) has a high tendency to oxidation as the noble metal(copper) has the tendency to reduction.

when we place zinc in copper sulfate solution, the more negative zinc oxidized to give zinc ion and two electrons. On the other hand, copper gets reduced by accepting this two electrons and deposited in the zinc rod.
