Add 50 mL deionised water and 5 drops superfloc solution. Shake vigorously for 5 seconds, centrifuge or filter (No 42 Whatman paper). Dilute extracts (1 + 9) with deionised Sodium dithionite (also known as sodium hydrosulfite) is a white crystalline powder with a sulfurous odor. Although it is stable in dry air, it decomposes in hot water and in acid solutions. See more The structure has been examined by Raman spectroscopy and single-crystal X-ray diffraction. The dithionite dianion has C 2 symmetry, with almost eclipsed with a 16° O-S-S-O torsional angle. In the dihydrated form … See more Sodium dithionite is produced industrially by reduction of sulfur dioxide. Approximately 300,000 tons were produced in 1990. The route using zinc powder is a two-step process: 2 SO2 + Zn → ZnS2O4 ZnS2O4 + 2 NaOH → Na2S2O4 + … See more The wide use of sodium dithionite is attributable in part to its low toxicity LD50 at 2.5 g/kg (rats, oral).

Sodium dithionite - Wikipedia

Websodium dithionite is still a hotly debated topic [ 11. Sodium dithionite reduces many flavoenzymes to the free radical level, a one electron reduction [2]. On the other hand, reports of two-electron reduction by sodi- um dithionite have appeared recently [3-51 and are now generally accepted. The question of mechanism ...
