You will be given the spontaneous redox reaction (or enough information regarding it) so that you can construct and label a battery. For the magnesium–nickel battery of Problem 10.67:

(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 10.67

You will be given the spontaneous redox reaction (or enough information regarding it) so that you can construct and label a battery. Include a salt bridge filled with NaCl(aq) and indicate which way the Na⁺(aq) and Cl^– (aq) ions flow.

Mg + Ni²⁺ → Mg²⁺ + Ni

Draw a battery similar to the one you drew for WorkPatch 10.7. Make sure you label which way the electrons flow, and also label the cathode, +, and anode, –.

Data from WorkPatch 10.7

Design and label a battery based on the redox reaction between magnesium metal and silver ions:

Does your battery show electrons flowing from the Mg electrode to the Ag electrode? It should!
