Kodi sulphate ya sodium yopanda madzi ndi yofanana ndi sulphite ya sodium yopanda madzi?

Sodium Sulphate Anhydrous, woyera yunifolomu granules zabwino kapena ufa.

Zopanda fungo, zamchere komanso zowawa.

Kachulukidwe 2.68g/cm. Malo osungunuka 884 ℃.

Kusungunuka m'madzi, kusungunuka kumawonjezeka mofulumira ndi kuwonjezeka kwa kutentha mkati mwa 0-30.4 ℃. Amasungunuka mu glycerol, osasungunuka mu ethanol.

Njira yamadzimadzi ndiyosalowerera. Pamene njira yamadzimadzi ndi yotsika kuposa 32.38 ℃, idzakhala yonyezimira ndikuwomberedwa ngati decahydrate.

Pamwamba pa 32.38 ℃, imayamba kunyezimira ndi anhydrous sodium sulphate.

Amagwiritsidwa ntchito makamaka ngati zodzaza utoto ndi othandizira kuti asinthe ndende za utoto ndi zothandizira kuti ndende yokhazikika ifikire.

Itha kugwiritsidwanso ntchito ngati utoto wachindunji, utoto wa sulfide, utoto wochepetsera pakupaka utoto thonje, utoto wachindunji wa asidi mu utoto wa silika ndi ubweya wa nyama zoletsa ulusi, zimathanso ntchito ngati kusindikiza silika nsalu kuyenga pamene m'munsi chitetezo mtundu wothandizira.

M'makampani opanga mapepala, amagwiritsidwa ntchito ngati chophikira popanga sulphate zamkati. M'makampani opanga mankhwala, amagwiritsidwa ntchito ngati mankhwala barium mchere poizoni.

Kuphatikiza apo, imagwiritsidwanso ntchito m'magalasi ndi mafakitale omanga.

Sodium sulfite anhydrous, woyera galasi ufa, sungunuka m'madzi (pa 0 ℃, 12.54g / 100ml madzi; pa 80 ℃, 283g/100ml madzi), kusungunuka kwakukulu kuli pafupi 28% pa 33.4 ℃, yankho lamadzi ndi lamchere, mtengo wa PH ndi pafupifupi 9 ~ 9.5.

Pang'ono sungunuka mowa, insoluble mu madzi klorini, ammonia. Zili choncho mosavuta oxidized kuti sodium sulphate mu mpweya, ndi decomposed kuti sodium sulfide pa kutentha kwakukulu. CAS No. 7757-83-7.

Kugwiritsa ntchito mankhwala:

Anhydrous sodium sulfite amagwiritsidwa ntchito popanga filimu.
