To find the correct oxidation state of in [Cr(NH3)4Cl2] + (the ion), and each element in the ion, we use a few rules and some simple math.First, since the io
c) The total charge of the ion is 3-. while the oxidation state of O is always 2-. Because there are 4 oxygen atoms with 2- oxidation state which gives 8- charge in total from oxygen, P must have an oxidation state of 5+ \text{\textcolor{#c34632}{P must have an oxidation state of 5+}} P must have an oxidation state of 5+ to equal 3-.

Lets assume oxidation number of C in C H X 3 O H \ce{CH3OH} CH X 3 OH is x x x. Oxidation number of H is +1 and O is -2. The sum of the oxidation numbers of all atoms in a neutral compound is zero.
Write separate equations for oxidation and reduction. Reduction: + 1 H + e − → 0 H ( i n H 2) Oxidation: 0 A l → + 3 A l + 3 e −. Multiply the reduction equation by 3 to obtain an equation with the same number of electrons as the oxidation equation: Reduction: 3 H + + 3 e − 3 H 0 ( i n H 2) Oxidation:In addition to CrO 3, other commonly used oxidizing agents include potassium permanganate (KMnO 4) and sodium dichromate (Na 2 Cr 2 O 7). Any of these reagents can be used to oxidize secondary alcohols to form ketones and primary alcohols to form carboxylic acids. Tertiary alcohols remain unreactive to oxidation.

Cr has, at first, N° of oxydation +3 and becomes +6. For make this passage Cr gives 3 electrons #[Cr(OH)_4]^(-) = CrO_4^(2-) + 3e^-# for balance the charge, i put on the left 4 negative charges as #OH^-# and i obtain on the right 4 mol of water #[Cr(OH)_4]^(- ) +4OH^(-) = CrO_4^(2-) + 3e^(-) + 4 H_2O#. The Oxygen, at first,has oxydation number1dH1L.
