Abstract

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^), Uo~2~^++5^) etc. The formation of a brown coloured product by the interaction of vanadium with the reagent has also been mentioned by some authors^6^) 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.
