1. From the measurement of partition of phenol between benzene and the aqueous solution of silver nitrate, it was found that the silver nitrate elevates considerably the solubility of phenol in the aqueous solution contrary to the salting out effects of other ordinary salts. 2. From the measurements of the depression of freezing point of the aqueous solutions of these substances, it has been proved that the “salting in” action of silver nitrate is due to the formation of a complex ion, [Ag.C6H6O]., in the aqueous solution and the chemical equilibrium, Ag^.+C_6H_5OH=[Ag.C_6H_6O]^., is established there.
(1) The oxidation velocity of stannous chloride in alkaline solutions with air was studied. It was found to be the same as that of sodium sulphite when the concentration of alkali is greater than about 0.2 normal under the given condition. (2) The effect of temperature was small. (3) The dissolution velocity of oxygen in alkaline solutions was calculated indirectly.
