Notes:
1,8-Dihydroxy naphthalene 3:6 di sulphonic acid is known to form coloured complexes with a number of metal ions. A few of the references worth mentioning are those on Ti(iv)1), Fe(iii)2, Cu(ii)3), Cr(vi)4), Uo2++5) etc. The formation of a brown coloured product by the interaction of vanadium with the reagent has also been mentioned by some authors6) but details about its behaviour and composition are lacking. It was, therefore, thought worth-while to determine spectrophotometrically the composition of a vanadyl complex which in our case was pink in colour.
