Work in groups on these problems. You should try to answer the questions without referring to your textbook. If you get stuck, try asking another group for help.

Balance the following redox reactions:

1. $$\ce{Bi(OH)_3 + SnO_2^{2-} \rightarrow SnO_3^{2-} + Bi}$$ (basic solution)
2. $$\ce{S_2O_3^{2-} + I_2 \rightarrow I^- + S_4O_6^{2-}}$$ (acidic solution)
3. $$\ce{MnO_4^- + I^- \rightarrow MnO_2 + I_2}$$ (basic solution)
