Spectroscopic and Conductometric Study of Dyes with Different Anions

摘要

In the present work the author has pararosaniline as the carbonium ion dyestuff which is highly soluble in water to produce dense red colored solution. But when the dye reacts with different anions producing different adducts which may be ionic or covalent. The anions studied are phosphomolyda date, silicotungstate, N3 and SCN. Conductometric titrations have been carried out to decide the ionic and covalent nature of the adducts produced in the solution. Spectroscopic study has been carried out for the said anions.
