Abstract
Abstract In order to examine the correlation between sodium hydrosulfide and sodium monosulfide, the reduction of sodium m-nitrobenzene sulfonate by these aqueous sulfides has been studied kinetically. The rates of the hydrosulfide reduction and the main reaction of the monosulfide reduction were found to be proportional to the concentration of the nitro compound and the square of the concentration of the reducing agent. In the hydrosulfide reduction, the hydroxide ion concentration has a negative effect on the initial state and a positive effect on the final state. The polarographic study on the hydrosulfide reduction confirmed the presence of disulfide ions. From the available data, the correlation among the alkaline sulfides in the reduction was discussed.
