Molecular weight: 154.12
Fat: 1.eight
Melting position: 64 deg C
Melting warmth: 54.84KJ / mol (13.2KCal / mol)
Humidity position: 60% relative humidity
Stability point: significantly less than 50 ordmC
Solubility: 20 ordmC, 1 carved white block, carved white powder, carved white particles need 1.2 copies of drinking water dissolved (forty five%)
70 ordmC, a carved white block, carved white powder, carved white tablets need to have one portion of water dissolved (50%)

Chemical houses:
A. Carved white block (powder, grain) easy to damp exotherm, 80 ordmC started to decompose, the release of H2S, need to have to dry reduced temperature preservation.
6NaHSO2 middot CH2O + 3H2O – #8594 4NaHSO3 + 2HCOONa + 2H2S + HCOOH + 3CH3OH
B. When the temperature rose to a hundred and ten ordmC, carved white block (powder, grain) decomposition, the molecules of formaldehyde spEPT launch new [H], the strongest reduction pressure.
NaHSO2 middot CH2O – #8594 NaHSO2 + CH2O
NaHSO2 + H2O – #8594 NaHSO2 + two [H]
C. Carved white block (powder, grain) is divided into oXiHu (West Lake) Dis.dants, this kind of as with the I2.
NaHSO2 middot CH2O + 2H2O + 2I2- #8594 NaHSO4 + 4HI + CH2O
D. Carved white block (powder, grain) ought to be in alkaline medium PH gt 8, acid (acid limit PH gt 3) can make carved white block decomposition of hydrogen sulfide.
