Sodium hydrosulfide is the chemical compound with the formula NaSH. This compound is the product of the half-neutralization of hydrogen sulfide (H 2 S) with sodium hydroxide (NaOH). NaSH and sodium sulfide are used industrially, often for similar purposes. Solid NaSH is colorless. The solid has an odor of H 2 S owing to hydrolysis by ...
Sodium sulfide is a chemical compound with the formula Na 2 S, or more commonly its hydrate Na 2 S·9H 2 O.Both the anhydrous and the hydrated salts in pure crystalline form are colorless solids, although technical grades of sodium sulfide are generally yellow to brick red owing to the presence of polysulfides and commonly supplied as a crystalline mass, in flake form, or as a fused solid.
Sodium hydrogen carbonate (Sodium bicarbonate) – NaHCO 3; Sodium hydrosulfide – NaSH; Sodium hydroxide – NaOH; Sodium hypobromite – NaOBr; Sodium hypochlorite – NaOCl; Sodium hypoiodite – NaOI; Sodium hypophosphite – NaPO 2 H 2; Sodium iodate – NaIO 3; Sodium iodide – NaI; Sodium manganate – Na 2 MnO 4; Sodium molybdate ...
Thus, solutions of sodium dithionite cannot be stored for a long period of time. [3] Anhydrous sodium dithionite decomposes to sodium sulfate and sulfur dioxide above 90 °C in the air. In absence of air, it decomposes quickly above 150 °C to sodium sulfite, sodium thiosulfate, sulfur dioxide and trace amount of sulfur.
Structure of anhydrous sodium sulfite. Sodium sulfite can be prepared by treating a solution of sodium hydroxide with sulfur dioxide. When conducted in warm water, Na 2 SO 3 initially precipitates as a white solid. With more SO 2, the solid dissolves to give the disulfite, which crystallizes upon cooling. [2] SO 2 + 2 NaOH → Na 2 SO 3 + H 2 O
Ammonium hydrosulfide, a component of "stink bombs" has not been isolated as a pure solid. Some compounds described as salts of the sulfide dianion contain primarily hydrosulfide. For example, the hydrated form of sodium sulfide, nominally with the formula Na 2 S · 9 H 2 O, is better described as NaSH · NaOH · 8 H 2 O.
However, because some brands add seasonings and sauces, double-check nutrient labels to avoid edamame products with excess added sugar and sodium. How to Choose a Snack for Better Cholesterol
