Draw the Galvanic cells run by the following reactions. Label the anode, cathode, which direction the electrons flow in, and the substances on each side of the cells.

Question

1. CI2 (aq) + H2 (aq) > 2CI- (aq) + 2H+ (aq)

2. 2AI (s) + 3Pb2+ (aq) > 2AI3+ (aq0 + 3Pb (s)

3. 2Hg2+ (aq) + Zn (s) > Hg2^2+ (aq) + Zn^2+ (aq)

Answer 1

In each question simple figure out what atom is reduced and which atom is oxidized. Put what is reduced on the cathode. Put what is oxidized on the anode.

This is similar to the past two questions you asked. Would you like to meet for a lesson?
