solution and left it for some time.

After some time, she observed that
Solution of
blue vitriol
D) Zinc strip slowly coated with copper
II) Copper settle at the bottom of the beaker.
|||) Blue colour of the solution becomes fade.

The correct observations (s) is/are
a) I and II
b) I and III
Only III
d) I, II and III​

Answer 1

Explanation:

When a strip of zinc metal is placed into a blue solution of copper(II) sulfate ( Figure below ), a reaction immediately begins as the zinc strip begins to darken. If left in the solution for a longer period of time, the zinc will gradually decay due to oxidation to zinc ions. At the same time, the copper(II) ions from the solution are reduced to copper metal (see Figure below ), which causes the blue copper(II) sulfate solution to become colorless.
