MW: 311.8
EINECS: 233-653-7
Kekahi hehee:652 °C (kukui)
Kahi e hoʻolapalapa ai: 1085 °C
Nānā: ʻO ka pauka kristal keʻokeʻo
Pilikino : Māmā Māmā
Nā waiwai kemika:
ʻO ka sulfate kala he mau kristal liʻiliʻi a i ʻole ka pauka, kala ʻole a ʻālohilohi. Loaʻa ma kahi o 69% kālā a lilo i hina ke ʻike ʻia i ka mālamalama. Hehee ma 652°C a decomposes ma 1,085°C. Hoʻoheheʻe hapa i loko o ka wai a hoʻoheheʻe loa ʻia i loko o nā hāʻina i loaʻa ka ammonium hydroxide, nitric acid, sulfuric acid, a me ka wai wela. ʻAʻole e hoʻoheheʻe i ka waiʻona. He haʻahaʻa kona solubility i ka wai maʻemaʻe, akā hoʻonui ia i ka wā e emi ai ka pH o ka hopena. Ke kiʻekiʻe ka manaʻo o nā ion H+, hiki iā ia ke hoʻoheheʻe nui.
Noi:
Hoʻohana ʻia ka sulfate kālā ma ke ʻano he catalyst e oxidize long chain aliphatic hydrocarbons i ka hoʻoholo ʻana i ka koi oxygen kemika (COD). He mea hoʻoikaika ia i ka mālama ʻana i ka wai ʻino a kōkua i ka hana ʻana i nā papa metallic nanostructured ma lalo o Langmuir monolayers.
Hiki ke hoʻohana ʻia ka sulfate kālā ma ke ʻano he reagent kemika no ka hoʻoholo ʻana i ka colorimetric o nitrite, Vanadate a me fluorine. Ka hoʻoholo ʻana o ka colorimetric o ka nitrate, phosphate, a me ka fluorine, ka hoʻoholo ʻana o ka ethylene, a me ka hoʻoholo ʻana o ka chromium a me ka cobalt i ka nānā ʻana i ka maikaʻi o ka wai.
Hiki ke hoʻohana ʻia ka sulfate kālā ma nā haʻawina aʻe:
ʻO ka Iodination reagent i hui pū me ka iodine no ka synthesis o nā iododerivatives.
ʻO ka hui ʻana o nā uredines iodinated.
Hōʻike:
Hoʻopili a me ka waiho ʻana:
Hoʻopili: 100g / ʻōmole, 1kg / ʻōmole, 25kg / pahu
Ka mālama ʻana: E hoʻopaʻa ʻia ka ipu, waiho i loko o kahi pahu paʻa, a mālama i kahi maloʻo a maloʻo.
