a. Sn4+(aq) is the reducing agent and Cr(s) is the oxidizing agent.
b. Cr(s) is the reducing agent and Sn2+(aq) is the oxidizing agent.
c. Sn4+(aq) is the reducing agent and Sn2+(aq) is the oxidizing agent.
d. Cr(s) is the reducing agent and Cr3+(aq) is the oxidizing agent.

  1. Oxidized: lost electrons, became more positive.
    a) Cr is oxidized, so it is the reducing agent. Sn4+ gains electrons, so it is reduced, so it must be the oxidizing agent.

    So a is not the asnwer
