Electrons flow from the cadmium electrode to the nickel electrode in a galvanic cell using nickel and cadmium electrodes with 1 M aqueous solutions of NiCl2 and Cd(NO3)2. The cadmium electrode is the anode. The correct line notation for this cell is Cd(s) | Cd2+(aq) || Ni2+(aq) | Ni(s).

1. For questions 10 and 11 consider the construction of a galvanic cell using nickel and cadmium
electrodes and 1 M aqueous solutions of NiClz and Cd(NO3)2 10)In this cell, electrons flow
from the__electrode to the__electrode and the Cd electrode is called the a. Cd, Ni; anode b. Ni,
Cd aode c. Ni, Cd; cathode d. Cd, Ni cathode 11)What is the correct line notation for this cell? a.
Cd(s) Ni2 (aq II Cd2*(aq) | Ni(s) b. Cd(s) | Cd2*(aq) I| Ni(a) Ni(s) c. Ni(s) | Ni2 (aq) I| Cd2*(aq)
| Cd(s) d. Ni(s) Cd2"(aq) || Ni2-(aq) | Cd(s)
Solution
10.
Electrons flow from Cd to Ni electrode and Cd is anode
Because,
E 0
Cd2+/Cd = - 0.40 V ( lower )
E 0
Ni2+/Ni = - 0.23 V ( higher )
11.
(b)
Cd (s) | Cd 2+
(aq.) || Ni 2+
(aq.) | Ni (s)
