Zinc is more reactive than copper and hence it displaces copper from copper sulphate solution. As a result a number of holes were observed on the zinc plate.

When a zinc plate is placed in an aqueous solution of copper sulfate, elemental copper forms, as represented by the equation above. Which of the following represents the reduction half-reaction of the

What happens when a piece of(a) zinc metal is added to copper sulphate solution?(b) aluminium metal is added to dilute hydrochloric acid?(c) silver metal is added to copper sulphate solution?Also, write the balanced chemical equation if the reactionoccurs

The colour of the solution observed after 30 minutes of placing zinc metal to coppersulphate solution is

The ore of zinc containing its sulphide

Shorten to 100 words: The experiment includes the process of decantation between copper solid and the supernatant. During this procedure, some copper solid was lost when the supernatant solution was separated from the precipitate. This could have been due to the incomplete separation of the solution and the precipitate which could have led to the loss of copper solid recovered (final mass) and therefore reduction of percentage yield. Another possible source of error could be that the reaction between CuSO4 and Zinc powder was incomplete. This indicates that the amount of zinc added to the solution was less than the stoichiometric amount required to completely displace all the copper ions. As a result, the actual amount of copper solid produced was less than the theoretical yield. This discrepancy reduced the percentage yield of copper.
