List a series of test that would determine the order of activity (least active to most active) for the following metals: Zn, Mn, and Ag.

Answer 1

Zn(s) + MnCl2 ==>
Zn(s) + AgNO3 ==>
Mn(s) + AgNO3 ==>
Mn(s) + Zn(NO3)2 ==>

The above four will tell you if Zn is above Mn and Ag and if Mn is above Ag and Zn.

You will need two more to check where Mn is with respect to Ag
