Question

Which of the following reaction will not occur? Write reason for your choice.
a) Zinc sulphate + Copper --------------⇒ Copper sulphate + Zinc
b) Copper sulphate + Zinc --------------⇒ Zinc sulphate + Copper

Answer 1

Answer:

because that is science logic lol jk here is the answer hope it helps

Explanation:

Answer: When zinc is added to copper sulphate (CUSO4) solution due to more reactivity of zinc, cooper is replaced by the zinc and forms zinc sulphate. During the process, the colour of the solution changes from blue to colourless.

Since Zinc is placed much above Copper in the reactivity series , so zinc is much more reactive than copper . In a galvanic cell , zinc is made the cathode because it can easily lose electrons and copper is made the anode because it can gain electrons much easily as compared to zinc due to its low reactivity
