Bodyweight: one.eight
Melting level: sixty four deg C
Melting heat: 54.84KJ / mol (13.2KCal / mol)
Humidity stage: 60% relative humidity
Balance point: less than fifty ordmC
Solubility: 20 ordmC, one carved white block, carved white powder, carved white particles need to have one.2 copies of water dissolved (45%)
70 ordmC, a carved white block, carved white powder, carved white tablets want one part of water dissolved (fifty%)
Actual physical homes: carved white block, carved white powder, carved white particles with a sturdy lowering salt, white condensed lumps or powder, granules, was alkaline safety.
Chemical houses:
A. Carved white block (powder, grain) straightforward to damp exotherm, eighty ordmC began to decompose, the release of H2S, need to have to dry low temperature preservation.
6NaHSO2 middot CH2O + 3H2O – #8594 4NaHSO3 + 2HCOONa + 2H2S + HCOOH + 3CH3OH
B. When the temperature rose to 110 ordmC, carved white block (powder, grain) decomposition, the molecules of formaldehyde spEPT launch new [H], the strongest reduction force.
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, such as with the I2.
NaHSO2 middot CH2O + 2H2O + 2I2- #8594 NaHSO4 + 4HI + CH2O
D. Carved white block (powder, grain) must be in alkaline medium PH gt 8, acid (acid restrict PH gt 3) can make carved white block decomposition of hydrogen sulfide.
