Additional information

The water solubility of REACTION MASS OF NITROSYLSULFURIC ACID AND SULPHURIC ACID can not be assessed according to the OECD guideline 105, as lifetime of the test item is extremely short in contact with water. Hydrolysis occurs following the chemical reaction below : HSO4NO + H2O H2SO4 + HNO2 HNO2 produced undergoes other complex reactions and by progressive addition of water, the ultimate transformation of HSO4NO nitrogen gives for 2/3 a mixture of NO and NO2 which are toxic gases and for 1/3 nitric acid.
