Thermal studies on oxalate complexes. V. Potassium tris(oxalato)aluminate(III) trihydrate

The results on the studies of various thermodynamic parameters for the oxidation of seven sulpha drugs, viz. sulphanilamide, sulphacetamide(s), sulphasomidine, sulphaguanidine, sulphadiazine, sulphapyridine and sulphamethizole, by the peroxydisulphate ion are reported and discussed. All the reactions under study obeyed the Arrhenius equation. The validity of the isokinetic relationship and other related equations have been tested. An attempt has been made to correlate these findings with the mechanism operative in the oxidation of sulpha drugs by the peroxydisulphate ion.
