Incompatibles Of Iron Salts In General

All substances containing tannic or gallic acid form an intense black with ferric salts. Preparations of iron are therefore incompatible with all vegetable astringent solutions, and the only infusions with which they can be prescribed are infusions of quassia and of calumba. It is a common mistake to forget that because of its tannin, the tincture as well as the infusion of digitalis makes an inky mixture with iron preparations. Such a mixture may be clarified with a little diluted phosphoric acid, but after a few days a slight precipitate of ferric phosphate falls. Ferric salts render mucilage of acacia gelatinous.

Alkalies and their carbonates, lime water, calcium carbonate, magnesia and magnesium carbonate give green precipitates with ferrous, and brown with ferric salts.
