Application of Sodium Sulfite Heptahydrate as Electrolyte in Electrochemical Research

Altowyan, Abeer S., et al. Nanomaterials, 2022, 12(19), 3272.

Sodium sulfite heptahydrate (Na2SO3·7H2O) can be used as an electrolyte in electrochemical cells, providing a source of sodium ions (Na+) and sulfite ions to participate in the electrochemical reactions that occur in the battery. For example, in the study of the electrochemical performance of iridium oxide (IrOx) thin films, 0.5M sodium sulfite heptahydrate was used as the electrolyte to explore the reactivity of the hydrogen production catalyst.
Evaluation of photocatalytic performance in sodium sulfite heptahydrate electrolyte
· Firstly, IrOx thin films were prepared by spin casting as photoelectrochemical (PEC) hydrogen production catalysts.
· Subsequent photocatalytic activity measurements were performed using the nanocomposite electrode in 100 mL of 0.5 M (Na2SO3·7H2O) solution at room temperature by an OrigaFlex potentiostat.
· A surface area of 1cm2 is used as the photocathode (working electrode), and a Pt electrode with the same area as the counter electrode (auxiliary electrode). Simulate sunlight incident on the electrode surface, and standard white illumination is provided by a mercury-xenon light source.

Sodium Sulfite Heptahydrate Used in the Synthesis of Pyrazole -3-One Derivatives

Datar P A, et al. International Journal of Medicinal Chemistry, 2015, 2015.

Pyrazole-3-one compounds are designed as hypoglycemic drug candidates with antidiabetic activity. Pyrazole-3-one compounds can be obtained from different compound precursors, depending on their R group. In the synthesis process of substituted phenylhydrazine from substituted aniline, sodium sulfite solution is one of the important reaction conditions.
Reaction involved in sodium sulfite heptahydrate
· 5 g (0.037 mol) of substituted amino compound was dissolved in a mixture of 10.5 mL of concentrated HCl and an equal volume of water, cooled rapidly to 0 °C in order to obtain the hydrochloride of the base in a fine state of division.
· Gradual addition of a solution of 2.6 g (0.037 mol) of sodium nitrite in 6 mL of water was performed for diazotization. Stirring was continued for a few minutes, and the solution was filtered and added by using a separatory funnel to an ice-cold solution made of 41 g (0.156 mol) of sodium sulphite (96% Na2SO3·7H2O) in 100 mL of water containing 4 g of NaOH.
· After the solution was acidified, heated in a water bath, filtered and recrystallized, yellow needles were obtained. The precipitate was filtered off and dissolved in water and the solution was treated with a concentrated solution of sodium acetate. The free base separated out in an almost pure state.
