In the oxidation number change method the underlying principle is that the gain in the oxidation number (number of electrons) in one reactant must be equal to the loss in the oxidation number of the other reactant.

☆ Br + CrO4(2-) = Br2+Cr(OH)3 ☆

 Simplify the equation. The same species on opposite sides of the arrow can be canceled. Write the equation so that the coefficients are the smallest set of integers possible.2Cr+3(O-2H+1)3 + 3Br02 + 10OH- → 2Cr+6O-242- + 6Br-1- + 8H2OFinally, always check to see that the equation is balanced. First, verify that the equation contains the same type and number of atoms on both sides of the equation.
