Phosphorus'okesaside

Phosphorus Uaʻike, a noho kaʻawale ia ma 1669 ma Kelemānia chemist H. Brandt. Ma ke ano maoli, ua hehee ai ua loaʻa i loko o ka palapala o ka hui wale. Major nā minelala hao - phosphorite Ca3 (PO4) 2 a me apatite 3Ca3 (PO4) 2 • CaF2 ole Ca5F (PO4) 3. Eia kekahi, o ka hehee ai ka hapa o ke kumuʻiʻo, a ua hoi i loaʻa ma ka niho a me nā iwi. Phosphorus mea loa hoopuni reacts me ka o oxygen, a chlorine. An oi o kēia mau waiwai i hanaʻia me ka hui 'okesaside (no ka P) +5, a me ka shortage - ma ka'okesaside moku'āina +3. phosphorus'okesaside e hoʻokū 'ia e kekahi mau nā papakuhikuhi i hōʻike' ana i kekahi mau Nine Inch. Iwaena o lakou, i ka loa, he pono ole - ka P2O5 a me ka P2O3. Other pohihihi a poorly? Anoee oxides i: P4O7, P4O8, P4O9, PO a me ka P2O6.

Ke naoh o elemental phosphorus, oxygen ma'okesaside i wahi lohi. Hoihoi i loko o konaʻike likeʻole. Mua, i loko o ka pouli, maopopo lea i nanaia glow, a ua hahai aku la. Ka lua,'okesaside o ka Nine Inch waiwai mau e wahi me ke kahua o ka'okikene kolu. He mea pono e hoʻolimalima waena - phosphoryl PO - noaia: P + O2 → PO + O, laila: O + O2 → O3. Ekolu, ka'okesaside aie i ka abrupt loli i loko o ka pou conductivity o ka Ambient lewa ma muli i kona ionization. Hoʻokaʻawale o ka malamalama me ka nui reheating, ma Nine Inch reactions ua kapaia chemiluminescence. Ma humid hana kūpono uliuli chemiluminescence ku i ke kahua o ka waena PO.

phosphorus'okesaside ia lŘlŘ ma ka kekahi i oxygen lehulehu wale. Ka mea e ole ia ma lalo o ka palena iki paepae, a ma luna o ka mea i kā mākou hapa puʻe o O2. Wā mawaena iho hilinaʻi nui ma luna o ka mahana a me nā aʻe. No ka laʻana, ma lalo hae rula, o ka naoh uku o ke gula oxygen, phosphorus'okesaside piʻina a ka mea 300 mmHg ihoiho. Art. i ka aneane Aʻohe ka wā o ka oxygen ma hapa puʻe ua laila hoemi a me Falls hiki 700 mm o Hg. Art. a ma luna. Pela, ke'okesaside uaʻaʻole i hanaʻia ma lalo ano o keia, no laila, e like me phosphorus aneane ole oxidized.

phosphorus pentoxide

Ka loa typical phosphorus pentoxide ka'okesaside a oi aku oxides o phosphorus, P2O5. He He keʻokeʻo ka pauka me ka pungent ala. I ka hoomaopopo ana i ka hui o kona hakakino ke kaupaonaʻana, ka mea i loaʻa i ka pono hoike o kona haʻilula P4O10. Kēia nonflammable waiwai nui, e heheʻe ma 565,6 C. Ka anhydride P2O5'okesaside -kislotny a pau ano waiwai, akā, ka mea, ua avidly ke kemu ona, no laila, ua hoʻohana 'ia e like me ka desiccant ke kinowai a me kinoea. phosphorus'okesaside hiki ke lawe i ka wai, i ka hapa o ka Nine Inch. Ke anhydride Ua hanaʻia ma ke'ā o ka phosphorus i loko o ka oxygen ma ka lewa, a me ka lewa, he lawa nui o O2 noaia: 4P + 5O2 → 2P2O5. Ua Ua hoʻohana 'ia i loko o ka? Iecaianoaaiiie oʻakika H3PO4. I ka hui 'ana me ka wai ke hana i ka ekoluʻakika.

• metaphosphoric: P2O5 + H2O → 2HPO3;
• pyrophosphoric: P2O5 + 2H2O → H4P2O7;
• Phosphoric: P2O5 + 3H2O → 2H3PO4.

phosphorus pentoxide reacts a pau me ka wai a me ka waiwai i loaʻa ka wai, e like me ka laau a me ka pulupulu. Kēiaʻano a he nui nui o ka wela i ke ahiahi, i ke ahi. Ua hoʻololi i nā hana metala ka popopo a me ka loa o keʻano ukiuki (ka mea'āʻili, maka) a me ka airway mucous membranes, e like ma nā hoʻohui like me haʻahaʻa me 1 mg / m³.

phosphorus trioxide

Phosphorous anhydride a phosphorus trioxide, P2O3 (P4O6) - mea he keʻokeʻo mea pōaka paa (mahuahuaʻano e like), i heheʻe i ka wela o ka 23,8 C a me ka maʻi hēhē ma 173,7 C. E like me ke keʻokeʻo phosphorous, P2O3 ka loa nahesa niho . Kēiaʻakika'okesaside, a me nā mea a pau kona waiwai. Phosphorus'okesaside 3 Ua hanaʻia ma muli o ia i ke kali'okesaside a'ā o ka noa waiwai (P) i loko o kekahi 'ia ma laila mea he deficiency o ka oxygen. Phosphorus trioxide reacts lohi me ka wai huihui e liloʻakika: P2O3 + 3H2O → 2H3PO3. Kēia phosphorus'okesaside reacts vigorously me ka wela ka wai, i ka reactions lawe wahi ma naʻano likeʻole, i ka hopena e hana i kaʻulaʻula phosphor (Hoʻololi 'allotropic podukt), phosphorus hydride a me kaʻakika: H3PO3 a me H3PO4. Thermal decomposition o P4O6 anhydride ukali ma cleavage o ka phosphorus nā'ātoma, kahi o ka hui i hanaʻia o nā oxides o P4O7, P4O8, P4O9. E like me ka mea 'ole ka mea e hoohalike ai P4O10. Ka loa? Anoee o kēia mau P4O8.
