Webb12 mars 2024 · In addition, ferrous ion picks up oxygen easily and becomes ferric (ferric chloride is deep red in concentrated solution (~20% or more), but quite definitely yellow in more dilute solutions (~5%)). The reaction 2Fe 2 + + 0.5 O 2 + 2H + --> 2Fe 3 + + H 2 O is favored with lower pH. In analytical chemistry, this salt is the preferred source of ferrous ions as the solid has a long shelf life, being resistant to oxidation. This stability extends somewhat to solutions reflecting the effect of pH on the ferrous–ferric redox couple. This oxidation occurs more readily at high pH. The ammonium ions make solutions of Mohr's salt slightly acidic, which slows this oxidation process. Sulfuric acid is commonly added to solutions to reduce oxidation to ferric iron.

WebbAt pH values >8.5, dissolved oxygen (DO) in the water will cause oxidation. However, at lower pH values, chlorine can be used as an oxidising agent. Ferrous sulphate (FeSO 4 .7H 2 O), also known as copperas, is usually available as a granular material.
