Problem

Which of the following statement(s) is/are true?

a. Copper metal can be oxidized by Ag + (at standard conditions).

b. In a galvanic cell the oxidizing agent in the cell reaction is present at the anode.

c. In a cell using the half reactions Al 3+ + 3e→ Al and Mg2+ + 2e- → Mg, aluminum functions as the anode.

d. In a concentration cell electrons always flow from the compartment with the lower ion concentration to the compartment with the higher ion concentration.

e. In a galvanic cell the negative ions in the salt bridge flow in the same direction as the electrons.
