Balance each of the following redox reactions occurring in acidic solution.
1. I−(aq)+NO−2(aq)→I2(s)+NO(g)
2. IO3−(aq)+H2SO3(aq)→I2(aq)+SO42−(aq)
3. NO3–(aq)+Sn2+(aq)→Sn4+(aq)+NO(g)
To allow a redox reaction be successful the reaction process must include reactants that are capable of donating and receiving electrons. Although a list of conventional half reduction reactions is available half reactions aren’t scientifically feasible. These half reactions are made using reference oxidation half reactions. The most frequently used source can be described as known as the Standard Hydrogen Electrode (SHE) which has a the potential of zero for electrodes.
