The effect of parent substance genesis on the reactivity of active sodium carbonate towards sulphur dioxide

Abstract

The reactivity of sodium carbonate towards sulphur dioxide was studied in dependence on the effect of genesis of sodium hydrocarbonate as the parent substance of the reacting solid. The reactivity expressed by means of the effective rate constant differed approximately one half of order of magnitude among five various samples. A qualitative correlation has been found between the bulk density of the parent substance and the reactivity of active sodium carbonate prepared thereof. Experimental evidence is given that the effect of genesis of the parent substance is not decisive for the reactivity of the active sodium carbonate towards sulphur dioxide. Henceforth, as the decisive factor for the reactivity of the sodium carbonate the way of its preparation from the parent substance must be considered.
