He aha ka paʻakai hydrogen sulufahate?

Paʻakai sulufahate - o kaʻakika paakai o ka paʻakai, a sulfuricʻakika. Denoted NaHSO4 ka waiwai kuleana. Paʻakai sulufahate mea he aniani moakaka aniani ka ole kekahi ala. Ke molar nuipa o ka waiwai, ua like ia 120,06 nā huna no kameleona, a me ka pa apŘ - 2,472 gram no cubic kenimika. Ua heheʻe i ka wela o ka +186 ° C. I paio hahana maoli nō ka waiwai hiki e malama elua polymorphic hoʻololi - i ka wela o ka +140 ° C a me +170 ° C.

Paʻakai sulufahate hiki ke reacted me ka mekala 'åkilikai, maalo ae la oia ma ka naoh i sulufahate. Penei, ma ka reacting ia me ka paʻakai hydroxide hana paʻakai sulufahate a me ka wai. Inā he ikaika hahana maoli nō kēia o ka ia mea (i i +250 ° C a oi) ka mea, ua Wāwahi loko paʻakai pyrosulfate a me ka wai.

Maʻamau, ka paʻakai sulufahate 'Aʻole i pane koke me nā waiwai, nae, sintering ia lŘlŘ ma ke ana wela i oi aku mamua +450 ° C, ia mea hiki ke reacting me ka paʻakai, a oxides.

Ka mea hiki waiwai o keia waiwai he nui: ka mea, ua hoʻohana 'ia i loko o nonferrous metallurgy (i koko), ka mea i hana i ka mea kemikala i loko o ka unuhi oxides sulfates. He He ikaika denaturing. Ua hoʻomano hoʻohana 'ia ma ka imu (kauoha aku kakau me ka meaʻai mea hoʻonui E514).

Eia naʻe, hoʻowahāwahā kona nui i loko o kanaka ola, paʻakai hydrogen sulufahate hiki no hoi e weliweli: i kekahi mekala 'åkilikai ikaika, o ka waiwai ka loa corrosive, ma ka hui' ana me ka ili ke haʻalele loa'ā, ma o na la nui poino a me ka maka. Ka mea nui weliweli ka haule ana i loko o ka gastrointestinal'āpana. He hoi loa nā palapala waiwai a me ka inhalation o ka ohu.

Aie i ka hopena maikaʻi 'ole o ka paʻakai bisulfate ma luna o ke kanaka kino o ka waiwai paha ma ka kūwaho hoʻi hōʻailona o ka "pilikia" mea he huinahalike alani, dissected mau diagonal ʻeleʻele kaula. A hoailona e olelo e pili ana i na pilikia o ka waiwai ole wale no kānaka akā, no hoi no ka mea i hoʻolilo 'ia, a pēlā hoʻi me nā kapu kau ma luna o kona? Iecaianoaaiiuo.

No ka paʻakai hydrogensulfate e pono ke hana i ka naoh ma waena o kia sulfuricʻakika a me ka paʻakai hydroxide, a me ka sulfuricʻakika e ia ma ka oi. E like me ka hopena, keia naoh produces paʻakai bisulfate a me ka wai.

Naʻe, ma mua oe i lawe i ka loaa ana o keia mea, e kiʻi iā ia iho paʻakai. Makaukau o ka paʻakai ua ole he huikau kaʻina hana, a, e hiki io kekahi o nā kiʻina hana a hiki i loko o ka hale.

Kekahi o ka mea mua kiʻina hana o ka naoh o ka paʻakai loaa hou ana o ka paʻakai kalepona (Na2CO3) ma ke kiʻekiʻe wela lanahu (puni +1000 ° C). i kona hopena, e loaa maemae paʻakai, a hoʻokaʻawale o kalapona monoxide. Alakaʻi i ka naoh uaʻaʻole he manawa ia e hoopau ana, akā, ma muli o ke kala o ka kalapona monoxide, e lilo i mea weliweli loa.

No ia mea, ka mea, ua invented kekahi papa hana o ka la hoomalolo - electrolysis o hoʻoheheʻeʻia paʻakai koloriside. I ka pono o keia iaoia mea ole wale kona hoahanau ola, akā, i uuku ma mua i loko o ka ka ho'ēmiʻana waiwai paio hahana maoli nō mahana: +600 ° C kahi +1000 ° C. Ia mea, i kēia iaoia hiki ke hoʻohana 'ia ma ka hale - ina, o ka papa, he mea i ka manawa kūpono o ka hahana maoli nō kēia o ka paʻakai koloriside (e like me ka paʻakai), e olelo mai ana wela.

Ma ke kumu o ka paʻakai - o chemically-ʻeleu hehee ai o ka papa'āweʻaweʻa kemika papaʻaina - hoomakaukau congeners paʻakai hydrogensulfate a me ka ole emi nui no ka manaʻo kanaka. Kēia waiwai a pau - paʻakai hydrosulfide,ʻakika paakai a me ka paʻakai hydrogen sulfide. Ua ho keʻokeʻo nā pōaka, denoted ma ka haʻilula NAH. Ua Ua loaa ma ka hele hydrogen sulphide ma ka pāʻoihana o ka paʻakai sulfide a me ka hydrogen sulfide ma ka hele ma paʻakai hydroxide pāʻoihana.

Paʻakai hydrosulfide reacts me alkalis a me nāʻakika, maʻalahi oxidized ma ka oxygen. Ma ka mahele heheʻe i ka iʻeleʻele. Ua Ua hoʻomano hoʻohana: i kekahi hapa o ka mea i hoʻohana e wehe i koe ili papa, māhele i nā mea hana o ka home, hoʻohana like maka mea no ka? Iecaianoaaiiie o na make butifos.
