In each of the following reactions, identify the atom oxidized, the atom reduced, and balance the equation.

1. KBr + Fe2(SO4)3 -> Br2 + K2SO4 + FeSO4
Here Br- loses an electron to form molecular Bromine. Hence it is getting oxidized.
Fe is gaining an electron since the ionic charge changes from Fe3+ to Fe2+. Hence Fe is getting reduced.
The balanced equation is as below:
2KBr + Fe2(SO4)3 -> Br2 + K2SO4 + 2FeSO4

2. Sn + HNO3 + H2O -> H2SnO3 + NO
Oxidation Number of Sn in H2SnO3: 3*2 - 2*1 = 4
Sn is getting oxidized since its ON is increasing from 0 to +4.
Oxidation Number of N in HNO3: 3*2 - 1 = 5
Oxidation Number of N in NO = 2
HNO3 is getting ...

  • Redox Reaction Titration

    Like acid-base reactions, redox reactions are a matched set -- you don't have an oxidation reaction without a reduction reaction happening at the same time. Oxidation refers to the loss of electrons, while reduction refers to the gain of electrons.
