Abstract

Abstract (1) The oxidation velocity of sodium sulphite in sodium carbonate solution of various concentrations was observed. The oxidation velocity was independent of the concentration of sodium sulphite under the condition of the present experiment, and the velocity constant was expressed as a linear function of the concentration of sodium carbonate approximately, when CNa2CO3 is greater than about 0.02 normal. (2) The effect of temperature was small. (3) The dissolution velocity of oxygen into sodium carbonate solution of various concentrations was obtained indirectly.
