Code: Select all

ICl3+H2O = ICl + HIO3 + HCl
The key is to remove distractions and reveal : I am positive.

-Spectator:

Code: Select all

I{3+} = I{+} + IO3{-}
1/2 Equan:

Code: Select all

I{3+} = I{+} | I{3-} = IO3{-}
Balance O:

Code: Select all

I{3+} = I{+} | I{3-} + 3 H2O = IO3{-}
Balance H:

Code: Select all

I{3+} = I{+} | I{3-} + 3 H2O = IO3{-} + 6 H{+}
Balance e:

Code: Select all

I{3+} + 2 e{-} = I{+}  | I{3-} + 3 H2O = IO3{-} + 6 H{+} + 2 e{-}
Merge:

Code: Select all

2 I{3+} + 3 H2O = I{+} + IO3{-} + 6 H{+}
+Spectators:

Code: Select all

2 ICl3 + 3 H2O = ICl + HIO3 + 5 HCl
