Solubility:
45%(20 centigrade): 1.2 dose of water is necessary for dissolving away 1 dose of Rongalite at 20centigrade.50%(70 centigrade): 1 dose of water is necessary for dissolving avay 1 dose of Rongalite at 70centigrade.
Physical Properties:
To be nominated for Rongalite is for the reason that it serves the color-discharging functionto fabrics as well as its appearance. Under different cooling conditions, it solidfies out into white lumps, powder, or granules.
Chemical Properties:
Presenting a powerful reduction behaviour, it acts as a salt of alkaline protection.
A. Easy to deliquescent, emit heat, begin to decompose at 80centigrade, and sulfurated hydrogen H2S being release:
6NaHSO2.CH2O+3H2O ?4NaHSO3+2HCOONa+2H2S+HCOOH+3CH3OH
B. Decompose completely when the temperature rises to 110centigrade, the intramolecular formaldehyde are splitted out, and then nascent hydrogen which is possessed of the strongest reducing power are produced:
NaHSO2.CH2O ?NaHSO2+ CH2O
NaHSO2 + H2O ?NaHSO2+ 2[H]
C. Under the influence of acidity, decompose at PH >3, emit H2S, so that it sould be present in alkline medium PH >8.
D. Decompose on contacting oxidant, take I2 for example:
NaHSO2.CH2O+2H2O+2I2 ?NaHSO4+4HI+CH2O |
