Hypophosphite and thallic perchlorate react in aqueous perchloric acid solution as follows: TlIII+ H3PO2+ H2O = TlI+ H3PO3+ 2H+ Hydrogen ion has no effect on the rate. The empirical rate law is: –d[TlIII]//dt=k[TlIII][H3PO2]//1 +K1[H3PO2] Complex formation between TIIII H3PO2 is suggested. Chloride increases by forming a more reactive complex.

ABSTRACT The oxidation of dissolved sulfur dioxide, sulfur(IV), by oxygen proceeds through the involvement sulfoxy radicals among which sulfate radical anion is main chain carrier. When organics are present, they inhibit sulfur(IV) via scavenging SO 4 − radicals. In contrast to previous studies, were limited mostly aliphatic compounds, this paper presents results effect 13 new volatile organic compounds (VOCs) including aromatic and heterocyclic on uncatalyzed autoxidation at pH 8.2 25°C....
