Cobalt(II) sulfate is used in storage batteries and electroplating baths, sympathetic inks, and as an additive to soils and animal feeds. For these purposes, the cobalt sulfate is produced by treating cobalt oxide with sulfuric acid. [1] Being commonly available commercially, the heptahydrate is a routine source of cobalt in coordination ...

Cobalt powder reacts with ammonia to form two kinds of nitrides, Co 2 N and Co 3 N. Cobalt reacts with phosphorus or arsenic to form Co 2 P, CoP, [2] CoP 2, [6] CoAs 2 and other substances. [2] The former three compounds are of interest as catalysts for water electrolysis .
Although harmless products were used, such as berries, and beetroot, many cosmetic products available at this time were still chemically dubious and even poisonous.
