Assuming the following reaction proceeds in the forward direction,
3 Sn4+(aq) + 2 Cr(s)  3 Sn2+(aq) + 2 Cr3+(aq)
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.
e. Cr(s) is the reducing agent and Sn4+(aq) is the oxidizing agent.


answer A

    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
