The metal cadmium tends to form 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.
(a) Write net ionic equations to explain each of the preceding observations.
(b) What can you conclude about the position of cadmium in the activity series?
(c)What experiments would you need to perform to locate more precisely the position of cadmium in the activity series?
