Problem: The metal cadmium tends to form Cd2+ ions. The following observations are made: (i) When a strip of zinc metal is placed in CdCl2(aq), cadmium metal is deposited on the strip. (ii) When a strip of cadmium metal is placed in Ni(NO3)2(aq), nickel metal is deposited on the strip.Which elements more closely define the position of cadmium in the activity series?

🤓 Based on our data, we think this question is relevant for Professor Wright's class at CCNY.

We’re being asked to determine which elements more closely define the position of cadmium in the activity series.


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.
