Question

These experiments were preformed:

I. A copper wire was placed in a solution of AgNO3(aq). The copper dissolved and filments of silver metal grew on the remaining copper wire.

II. A copper wire was placed in a solution of Zn(NO3)2(aq). No reaction was detected.

III. An aluminum wire was placed in a solution of Zn(NO3)2(aq). The aluminum dissolved and Zn metal formed.

Rank the activity of these metal from the following

A: Most Active, B: 2nd most active, C: 3rd most active, D: least active

Cu

Al

Zn

Ag

Explanation / Answer

From 1)

Cupper > Ag in reactivity

2)

Copper < Zinc

3)

Al > Zinc

Ag --> least reactive since it is the one that forms and will not form again

So...

Al > Zn > Cu > Ag

A > B > C > D
