Kinetics of Bromination of Safranine by Peroxydisulphate ion in presence of Bromide ion.
Pak J Pharm Sci Jan ;13(2):45-51.

Kinetics of brominaiton safranine by peroxydisulphate ion in presence of bromide ion has been investigated at various temperatures and ionic strengths. The rate followed first order kinetics in peroxy disulphate and bromide ion each, and zero order kinetics in safranine. A linear relation was obtained for the variation of logarithm of rate constant (log k) with the square root of ionic strength of the media (u). The rate constants for the rate controlling step were evaluated and interpreted as a function of ionic strengths and temperatures. The values of activation parameters were also computed.
