HALF-REACTION METHOD I
To work out if a redox reaction is
occuring:
1) write a half reaction showing the
organic
reactant(s) & the product(s)
reactant(s) & the product(s)
2) complete a material
balance
in acid soln add H2O for additional O,
then add H+ for additional H.
in acid soln add H2O for additional O,
then add H+ for additional H.
in basic soln then add OH- to both sides
to equal H+, then cancel H2Os.
to equal H+, then cancel H2Os.
3) Complete a charge balance
add e- to the side that
is needed so that
the charge on both sides of the equation
balances
the charge on both sides of the equation
balances
