Question

When zinc rod is suspended in FeSO4 solution the temperature of the solution falls the temperature of the solution rises the temperature of the solution remains same the colour of the solution does not change

Answer 1

Explanation:

the blue colored remains electrically neutral. C. the temperature of the solution falls. D. the weight of zinc rod starts ...

Answer 2

Explanation:

Placing a zinc rod in a copper sulphate solution on the other hand will see a reaction - the zinc will dissolve (as it reduces the Cu

2+

ions to the elemental metal for the reason stated above), the blue colouration of the solution will fade and eventually disappear and copper metal will be deposited.

So weight of zinc rod starts increasing as Copper will be deposited on the Zinc rod.
