Question

Metals L, K, M and N and their are selectively reacted and yield the following data:

L^2+(aq) + 2K(s) = L(s) + 2K^+(aq)
K(s) +N^+(aq) = no change
K+(aq) + K(s) = K(s) +M^+(aq)
N(s) + M^+(aq) = N^+(aq) + M(s)

What is the strongest reducing agent?

Answer 1

The strongest reducing agent is the one that is most easily oxidized. Looking at the reactions given, we can determine that K(s) is easily oxidized since it is being consumed in two different reactions. Therefore, K(s) is the strongest reducing agent.
