Chemical formula: MnCO3 Synonyms:manganese (II) carbonate, carbonate of manganese, manganous carbonate.Amount: 200 g Appearance and odour: fine, beige powder without appreciable odour. Grade: technical Description and uses: often used in pottery glazes as a colouring agent/opacifier, it’s also one of the most versatile manganese (II) compounds and a stable and handy precursor to much of manganese’s complex chemistry. Water insoluble but readily soluble in acids, it is a gateway to many other manganese compounds. Upon heating it starts losing carbon dioxide from about 200 C, in the presence of air yielding mixed oxides, mainly MnO2. In inert atmosphere (N2, Ar) or vacuum ...

Chemical formula: FeSO4.7H2O Synonyms: Ferrous sulfate; green vitriol; iron vitriol; copperas Amount: 200 g Appearance and odour: small green crystals without appreciable odour. Grade: 99 % Packaging: professional wide necked, white HDPE bottle with blue conical seal cap and tamper ring. Labelled. Bottle and cap are UN approved and reusable. Description and uses: a good source of Fe2+ (ferrous - oxidation state II) ions. This grade is highly and completely water soluble. It’s the basis of many Fe (II) salts. Oxidises easily to Fe (III), even by air. Precipitate with alkali, redissolve in acid to obtain other iron salts. Note that this is not a common garden grade ...
