Sodium dithionite is usually used as a reducing chemical in such experiments ( E?~ " 420 mV at pH 7 ).
12.
The reduction of the dinitrobenzidine compound can also proceed with tin ( II ) chloride instead of iron powder or with sodium dithionite in methanol.
13.
Raman spectroscopy and single-crystal X-ray diffraction studies of sodium dithionite in the solid state reveal that sodium dithionite exists in different forms.
14.
Raman spectroscopy and single-crystal X-ray diffraction studies of sodium dithionite in the solid state reveal that sodium dithionite exists in different forms.
15.
In one anhydrous form, the dithionite ion has C geometry, almost eclipsed with a 16?O-S-S-O torsional angle.
16.
Sodium dithionite ( Na 2 S 2 O 4 ), also known as sodium hydrosulfite, is the other main reagent used to brighten mechanical pulps.
17.
2, 6-Diphenylphenol is nitrated with diluted nitric acid to 4-Nitro-2, 6-diphenylphenol and subsequently reduced with sodium dithionite to the amine.
18.
A mixture of haemoglobin S ( Hb S ) in a reducing solution ( such as sodium dithionite ) gives a turbid appearance, whereas normal Hb gives a clear solution.
19.
The weak S-S bond causes the dithionite anion to dissociate into the [ SO 2 ] " radical anion in aqueous solution, which has been confirmed by ESR spectroscopy.
20.
The "'Marschalk reaction "'is the sodium dithionite promoted reaction of a phenolic anthraquinone with an aldehyde to yield a substituted phenolic anthraquinone after the addition of acid.
