Chemical homes:
A. Carved white block (powder, grain) straightforward to damp exotherm, eighty ordmC began to decompose, the release of H2S, require to dry minimal 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 pressure.
NaHSO2 middot CH2O – #8594 NaHSO2 + CH2O
NaHSO2 + H2O – #8594 NaHSO2 + 2 [H]
C. Carved white block (powder, grain) is divided into oXiHu (West Lake) Dis.dants, this sort of 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.
