Abstract
The influence of silver ions on the kinetics of safranine, an azine
dye, by peroxodisulphate has been ivestigated in the presence of sulphuric
acid colorimetrically. It was found that the rate is independent
of the concentration of safranine but first order dependent with respect
to the concentration of S2O82- and Ag(I). The reaction exhibits negative
salt effect. Acrylonitrile greatly inhibits the rate. A radical mechanism
has been proposed to explain the observed results.
