Ph of ferrous sulphate
Webb9 apr. 2024 · With a pH of less than two, this compound is highly corrosive and should not be touched with bare skin. It is also known by many synonyms including Combiron, Copperas, Ferobuff, Ferric Persulfate, green salts, and Slow Fe. It is made by treating ferrous sulfate with an oxidizing agent. WebbFerric sulfate solutions are usually generated from iron wastes. The actual identity of the iron species is often vague, but many applications do not demand high purity materials. It is produced on a large scale by treating …

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.

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. WebbThe pH was adjusted to between 3.0 and 6.0 with 2M sodium acetate, 0.8 ml of 1,10-phenanthroline solution was added and finally a further 10 ml distilled water. The absorbance at 515 nm was measured after 5-10 min.
