Isingeniso
I-Phosphoric acid iyinhlanganisela ye-inorganic ne-chemical formula H3PO4. Ibonakala njengamakristalu angenambala, asobala futhi ancibilika kalula emanzini. I-Phosphoric acid ine-asidi futhi ingasabela ngezinsimbi ukuze ikhiqize igesi ye-hydrogen, futhi isabelane notshwala ukuze yakhe i-phosphate esters.
I-Phosphoric acid isetshenziswa kabanzi ezimbonini ezahlukahlukene, kufaka phakathi njengempahla eluhlaza yokukhiqiza umanyolo, ama-ejenti okuhlanza, nezithasiselo zokudla. Ibuye isetshenziswe ekwenzeni usawoti we-phosphate, imithi, kanye nezinqubo zamakhemikhali. Ku-biochemistry, i-phosphoric acid iyingxenye ebalulekile yamaseli, ebamba iqhaza ku-metabolism yamandla kanye nokuhlanganiswa kwe-DNA, phakathi kwezinye izinqubo zezinto eziphilayo.
Ukukhiqizwa kwe-phosphoric acid ngokuvamile kuhilela izinqubo ezimanzi nezomile. Inqubo emanzi ihilela ukushisisa idwala le-phosphate (njenge-apatite noma i-phosphorite) ne-sulfuric acid ukukhiqiza i-phosphoric acid, kuyilapho inqubo eyomile ihilela ukubalwa kwetshe le-phosphate okulandelwa ukukhishwa okumanzi nokusabela nge-sulfuric acid.
Ekukhiqizeni nasekusetshenzisweni kwezimboni, i-phosphoric acid ibeka izingozi ezithile zokuphepha. I-phosphoric acid egxile kakhulu igqwala kakhulu futhi ingabangela ukucasuka kanye nokulimala esikhumbeni nasendleleni yokuphefumula. Ngakho-ke, izinyathelo ezifanele zokuzivikela kufanele zithathwe ukuze kugwenywe ukuthintana kwesikhumba kanye nokuhogela umhwamuko waso lapho kusingathwa i-phosphoric acid. Ngaphezu kwalokho, i-phosphoric acid nayo ibeka izingozi zemvelo, njengoba ukukhishwa ngokweqile kungaholela ekungcoleni kwamanzi kanye nenhlabathi. Ngakho-ke, ukulawulwa okuqinile kanye nezinqubo ezifanele zokulahla imfucuza kubalulekile ngesikhathi sokukhiqiza nokusetshenziswa.
