Question

a)when this cell is operating, the, ____ (Ag or Co) electrode will become the cathode.

b) electrons will flow from the ______ (Ag or Co) electrode

c) the _____ (Ag or Co) will experience an increase in mass

d) the u-shaped tube is called a ______

e) oxidation occurs at the ______ (Ag or Co)

f) positive ions migrate away from the ______ (Ag or Co)

g) the oxidization agent is _________

h) the particle which loses electrons is _______

i) when the cell reaches equilibrium, the voltage will be ______

j) triangleE= ________

Explanation / Answer

a) Ag because electrons are flowing to it and Electrons always flow from anode to cathode
b) Cu
c) Ag because it's gaining electrons
d) Salt bridge, it allows flow of ions
e) Cu, Oxidation occurs at anode
f) Cu
g) NO3-
h) Cu
i) 0.35V

j) 0.35

Reduction:
Ag+ + e- --> Ag(s) E = 0.80

Oxidation:
Cu(s) --> Cu2+ + 2e- E = -0.35

E = 0.80 - 0.35 = 0.45
