Abstract
DISODIUM- 1:8-dihydroxy naphthalene-3:6-disulphonate (trivial name chromotropic acid–sodium salt)yields coloured lakes with various cations1. Investigations of chelates of chromotropic acid with iron (III)2 and titanium (IV)3,4 have already been made. Sommer et al. have extensively examined chelates of titanium with chromotropic acid and various polyphenols5–7 and have discussed the structure of the metal chelates. The use of chromotropic acid in the colorimetric determination of uranium8,9has also been reported.
