You will be given the spontaneous redox reaction (or enough information regarding it) so that you can construct and label a battery.

For the chromium–silver battery of Problem 10.65:

(a) What is the oxidizing agent?

(b) What is the reducing agent?

(c) Which electrode gains mass with time?

(d) Which electrode is eaten away with time?

Data from Problem 10.65

Include a salt bridge filled with NaCl(aq) and indicate which way the Na⁺(aq) and Cl^–(aq) ions flow.

Cr + 3Ag+ → Cr³⁺ + 3Ag

Draw a battery Make sure you label which way the electrons flow, and also label the cathode, +, and anode, –.
