The rate of oxygen exchange between selenite ions and solvent water has been measured at 0°C over the pH range of 8.7–12.5. The rate of exchange, <I>R</I>, may be expressed by the rate law;<BR><I>R</I>=<I>k</I><SUB>1</SUB>[SeO<SUB>3</SUB><SUP>2−</SUP>]+<I>k</I><SUB>2</SUB>[HSeO<SUB>3</SUB><SUP>−</SUP>]+<I>k</I><SUB>3</SUB>[HSeO<SUB>3</SUB><SUP>−</SUP>]<SUP>2</SUP>+<I>k</I><SUB>4</SUB>[HSeO<SUB>3</SUB><SUP>−</SUP>][SeO<SUB>3</SUB><SUP>2−</SUP>].<BR>The observed rates were analysed in order to obtain the values of the rate constants. The over-all exchange reaction shows a negative salt effect; this has been shown to be an equilibrium salt effect on the dissociation of the hydrogen selenite ion.
