  1. Enter the formula of a chemical compound to find the oxidation number of each element. A net ionic charge can be specified at the end of the compound between { and }. For example: ZnCl4 {2-} or NH2NH3 {+}. Enter just an element symbol to show the common and uncommon oxidation states of the element.

  2. To find the correct oxidations state of S in H2SO4 (Sulfuric acid), and each element in the molecule, we use a few rules and some simple math.First, since th...

  3. Oxidation Number Calculator is a free online tool that displays the oxidation number of the given chemical compound. BYJU’S online oxidation number calculator tool makes the calculation faster and it displays the oxidation number in a fraction of seconds.

  4. Concentrated sulfuric acid is an oxidizing acid can oxidize carbon to carbon dioxide while sulfuric acid is reduced to sulfur dioxide. This is a redox reaction due to oxidation number of carbon and sulfur atoms are changed.

  5. To calculate oxidation numbers of elements in the chemical compound, enter it's formula and click 'Calculate' (for example: Ca2+, HF2^-, Fe4 [Fe (CN)6]3, NH4NO3, so42-, ch3cooh, cuso4*5h2o). Formula: The oxidation state of an atom is the charge of this atom after ionic approximation of its heteronuclear bonds.

  6. Oxidation of sulfur dioxide in the presence of a catalyst (e.g., platinum) yields sulfur trioxide, (9.8.8), which may be condensed to a liquid at room temperature (Bp = 45 °C). \[ \rm 2 SO_2 + O_2 \xrightarrow{Pt} 2 SO_3\]

  7. Balance and calculate the reducing and oxidizing agents in a redox (oxidation-reduction) reaction.
