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 substance most easily oxidized?
The substance most easily oxidized is the one that undergoes oxidation in the reactions. In this case, looking at the given reactions, we can see that K(s) is oxidized to K+(aq) in the first reaction, and K(s) is also oxidized to K(s) in the second reaction.
Therefore, the substance most easily oxidized is K (potassium).
