Code: Select all

PCl3 + ClO3{-} = Cl2 + P2O5 + HCl
Half :

Code: Select all

2 P{3+} = P2O5 || 2 ClO3{-} = Cl2 
Bal O:

Code: Select all

2 P{3+} + 5 H2O = P2O5 || 2 ClO3{-} = Cl2 + 6 H2O 
Bal H:

Code: Select all

2 P{3+} + 5 H2O = P2O5 + 10 H{+} || 2 ClO3{-} + 12 H{+} = Cl2 + 6 H2O 
Bal e:

Code: Select all

2 P{3+} + 5 H2O = P2O5 + 10 H{+} + 4 e{-} || 2 ClO3{-} + 12 H{+} + 10 e{-} = Cl2 + 6 H2O 
Eqt e:

Code: Select all

10 P{3+} + 25 H2O = 5 P2O5 + 50 H{+} + 20 e{-} || 4 ClO3{-} + 24 H{+} + 20 e{-} = 2 Cl2 + 12 H2O 
Merge:

Code: Select all

10 P{3+} + 4 ClO3{-} + 13 H2O = 5 P2O5  + 2 Cl2 + 26 H{+}
Specs:

Code: Select all

10 PCl3 + 4 HClO3 + 13 H2O = 5 P2O5  + 2 Cl2 + 30 HCl
Note: also

Code: Select all

HClO3 + HCl = Cl2 + H2O
