A standard galvanic cell is constructed with Co²+ | Co and Ag+ | Ag half cell compartments connected by a salt bridge. Which of the following statements are correct? Hint: Refer to a table of standard reduction potentials. (Choose all that apply.) 00 As the cell runs, anions will migrate from the Co²+ | Co compartment to the Ag+|Ag compartment. Ag+ is reduced at the cathode. Co²+ is reduced at the cathode. The cathode compartment is the Ag+|Ag compartment. In the external circuit, electrons flow from the Co²+|Co compartment to the Ag+|Ag compartment.
Consider the following half-reactions: (1) The strongest oxidizing agent is: (2) The weakest oxidizing agent is: (3) The weakest reducing agent is: (4) The strongest reducing agent is: Half-reaction E° (V) F₂(g) + 2e2F (aq) 2.870V Pb²+(aq) + 2e →→→ Pb(s)-0.126V Cr3+ (aq) + 3e →→ Cr(s) -0.740V (5) Will Cr³+ (aq) oxidize F"(aq) to F₂(g)? (6) Which species can be reduced by Pb(s)? If none, leave box blank. enter formula
