Acid-base properties and stability of sulfoxylic acid in aqueous solutions
@article{Makarov2010AcidbasePA, title={Acid-base properties and stability of sulfoxylic acid in aqueous solutions}, author={Sergei V. Makarov and D. S. Sal’nikov and Anna S. Pogorelova}, journal={Russian Journal of Inorganic Chemistry}, year={2010}, volume={55}, pages={301-304} }
A comparative study of decomposition of sulfoxylic acid S(OH) 2 and sulfoxylate anion and their reactions with formaldehyde in aqueous solutions with different acidity was carried out. Using the obtained results, the pK1 value of S(OH) 2 was determined for the first time.
