Problem

Given the following sets of reactions, which (if any) will not undergo a reaction?

I.    Pt(s) + KNO3(aq) →

II.   Ag(s) + Ni(NO3)2(aq) →

III.  Ca(s) + Zn(NO3)2(aq) →

IV. Fe(s) + Sn2+(aq) → 

V.  Ba2+(aq) + Cu2+(aq) →

A. I and II only

B. II, III, and IV only

C. III and IV only

D. II and V 

E. I, II, and V only

Solution

Using the concept of activity series, determine which among the given reactions will not proceed.

Recall that the activity series gives us the relative reactivities of metals to oxidation: metals higher in the activity series are more reactive to oxidation and vice-versa.
