Ua like anei ka sodium sulphate anhydrous me ka sodium sulphite anhydrous?

ʻO Sodium Sulphate Anhydrous ， ʻaʻahu keʻokeʻo maikaʻi granules a pauka paha.

ʻAʻala ʻole, paʻakai a ʻawaʻawa.

ʻO ka mānoanoa 2.68g/cm. Ka helu hehee 884 ℃.

Hiki ke hoʻoheheʻe ʻia i ka wai, piʻi wikiwiki ka solubility me ka piʻi ʻana o ka mahana i loko o 0-30.4 ℃. Hiki ke hoʻoheheʻe ʻia i ka glycerol, hiki ʻole ke hoʻoheheʻe ʻia i ka ethanol.

ʻAʻole kūʻokoʻa ka hopena wai. Ke emi ka wai ma lalo o 32.38 ℃, e hoʻoheheʻe ʻia a hoʻoheheʻe ʻia e like me ka decahydrate.

Ma luna o 32.38 ℃, hoʻomaka ia e crystallize me ka sodium sulphate anhydrous.

Hoʻohana nui ʻia ma ke ʻano he mea hoʻopihapiha no nā dyes a me nā mea kōkua e hoʻoponopono i ka neʻe ʻana o nā dyes a me nā mea kōkua i hiki ke loaʻa ka ʻike maʻamau.

Hiki ke hoʻohana ʻia e like me nā dyes pololei, nā sulphide dyes, nā mea hoʻoemi hoʻoemi i ka pulupulu hoʻoluʻu, nā waiʻakika pololei i ke kala ʻana i ka siliki a me ka hulu hipa holoholona fiber retarder.

I ka ʻoihana pepa, hoʻohana ʻia ia ma ke ʻano he mea kuke kuke i ka hana ʻana i ka pulp sulphate. I ka ʻoihana lāʻau lapaʻau, hoʻohana ʻia ia ma ke ʻano he antidote no ka paʻakai paʻakai barium.

Eia kekahi, hoʻohana ʻia ia i ka ʻoihana aniani a me ke kūkulu hale.

ʻO ka sodium sulfite anhydrous, ka pauka keʻokeʻo keʻokeʻo, hiki ke hoʻoheheʻe ʻia i ka wai (ma 0 ℃, 12.54g / 100ml wai; ma 80 ℃, 283g / 100ml wai), ʻo ka solubility kiʻekiʻe loa ma kahi o 28% ma 33.4 ℃, ʻo ka wai wai ka alkaline, ka ʻO ka waiwai PH ma kahi o 9 ~ 9.5.

Hiki ke hoʻoheheʻe ʻia i loko o ka waiʻona, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai chlorine, ammonia. He mea maʻalahi i ka sodium sulphate i ka ea, a decomposed i ka sodium sulphide ma ke kiʻekiʻe wela. Helu CAS 7757-83-7.

Hoʻohana kemika:

Hoʻohana ʻia ka sodium sulfite anhydrous no ka hoʻomohala kiʻiʻoniʻoni.
