Question

Herapathiteformed by which alkaloidal incompactibility

Answer 1

Herapathite, or iodoquinine sulfate, is a chemical compound whose crystals are dichroic and thus can be used for polarizinglight. The composition of herapathite has been shown by the Danish chemist Sophus Mads Jørgensen in 1877 and others to be 4QH2·3SO4·2I3·6H2O, where Q denotes the quinine molecule C20H24N2O2. The crystal can give up at least some of its water without losing its form and optical properties.



Herapathite can be formed by precipitation by dissolving quinine sulphate in acetic acid and adding iodine tincture
