The Oxidation of Alcohols

Primary alcohols can be oxidized to either aldehydes or carboxylic acids, depending on the reaction conditions. In the case of the formation of carboxylic acids, the alcohol is first oxidized to an aldehyde, which is then oxidized further to the acid. An aldehyde is obtained if an excess amount of the alcohol is used, and the aldehyde is ...

Sulfate Ion (SO₄²⁻)

Oxidation-Reduction: Sulfate is a very weak oxidizing agent. Since sulfur is in its maximum oxidation number in sulfate ion, this ion cannot act as a reducing agent.

6.2: Oxidation States (Oxidation Numbers)

This can also be extended to negative ions. Iron(II) sulfate is FeSO 4. The sulfate ion is SO 4 2-. The oxidation state of the sulfur is +6 (work it out!); therefore, the ion is more properly named the sulfate (VI) ion. The sulfite ion is SO 3 2-. The oxidation state of the sulfur is +4. This ion is more properly named the sulfate(IV) ion.

What is formed when you leave iron(II) sulfate in plain air?

Accordingly, the likely product when iron(II) sulfate is oxidized is basic iron(III) sulfate, i.e. approximately: $$ce{4FeSO4 + O2 + 2H2O -> 4Fe(OH)SO4}$$ However, the real weathering and aging of iron(II) sulfate in dry air actually yields a mixture of various compounds, including iron(III) sulfate and iron(III) oxide-hydroxide.
