thanks.

RedOx is happening! Get those spectator ions to safety. They're causing a distraction.estambre wrote:I need help...thanks.Code: Select all

Move the protons and water away too. Strip down to the bare essentials.
Code: Select all
Sb2O3 + IO3{-} + ? = Sb(OH)6{-} + I{+} + ?
{Note: Yes, I am positive that is iodine cation. That might have been a source of confusion.}
Now we can balance these two half equations by adding
Code: Select all
H{+}, H2O, e
Code: Select all
IO3{-} + ? = I{+} + ?
Code: Select all
Sb2O3 + ? = 2 Sb(OH)6{-} + ?
Code: Select all
IO3{-} + ? = I{+} + 3 H2O + ?
Code: Select all
Sb2O3 + 9 H2O + ? = 2 Sb(OH)6{-} + ?
Code: Select all
IO3{-} + 6 H{+} + ? = I{+} + 3 H2O + ?
Code: Select all
Sb2O3 + 9 H2O + ? = 2 Sb(OH)6{-} + 6 H{+} +?
Code: Select all
IO3{-} + 6 H{+} + 4 e = I{+} + 3 H2O
Code: Select all
Sb2O3 + 9 H2O = 2 Sb(OH)6{-} + 6 H{+} + 4 e
Code: Select all
IO3{-} + Sb2O3 + 6 H2O = I{+} + 2 Sb(OH)6{-}
Now put potassium on the anions, except the antimonite ion which we protonate.
Neutralise remaining positive charges with chlorine.
That is, add
Code: Select all
K{+} + 2 H{+} + 2 Cl{-}
Code: Select all
KIO3 + Sb2O3 + 6 H2O + 2 HCl = ICl + KCl + 2 HSb(OH)6
Code: Select all
KIO3 + Sb2O3 + 2 HCl + 6 H2O = 2 HSb(OH)6 + KCl + ICl
