Intshayelelo
I-asidi ye-Phosphoric yi-inorganic compound kunye ne-chemical formula H3PO4. Ibonakala njengeekristale ezingenambala, ezicacileyo kwaye zinyibilika ngokulula emanzini. Iasidi yePhosphoric ineasidi kwaye inokusabela ngesinyithi ukuvelisa igesi yehydrogen, kunye nokusabela ngeealkoholi ukwenza iphosphate esters.
I-asidi ye-Phosphoric isetyenziswa kakhulu kumashishini ahlukeneyo, kubandakanywa njengento ekrwada yokuvelisa izichumisi, ii-agent zokucoca, kunye nezongezo zokutya. Ikwasetyenziswa ekwenzeni iityuwa zephosphate, amayeza nakwiinkqubo zemichiza. Kwi-biochemistry, i-asidi ye-phosphoric iyinxalenye ebalulekileyo yeeseli, ethatha inxaxheba kwi-metabolism yamandla kunye ne-DNA synthesis, phakathi kwezinye iinkqubo zezinto eziphilayo.
Ukuveliswa kwe-asidi ye-phosphoric ngokuqhelekileyo kubandakanya iinkqubo ezimanzi nezomileyo. Inkqubo emanzi ibandakanya ukufudumeza ilitye le-phosphate (elifana ne-apatite okanye i-phosphorite) kunye ne-asidi ye-sulfuric ukuvelisa i-asidi ye-phosphoric, ngelixa inkqubo eyomileyo ibandakanya ukubalwa kwelitye le-phosphate elandelwa yi-extraction emanzi kunye nokusabela nge-asidi ye-sulfuric.
Kwimveliso yeshishini kunye nokusetyenziswa, i-phosphoric acid ibeka imingcipheko ethile yokhuseleko. I-asidi ye-phosphoric egxininiswe kakhulu iyingozi kakhulu kwaye inokubangela ukucaphuka kunye nomonakalo eluswini nakwindlela yokuphefumla. Ngoko ke, amanyathelo okukhusela afanelekileyo kufuneka athathwe ukuphepha ukudibanisa kwesikhumba kunye nokuphefumla imiphunga yayo xa uphatha i-phosphoric acid. Ngaphezu koko, i-asidi ye-phosphoric nayo ibeka imingcipheko yokusingqongileyo, njengoko ukukhutshwa okugqithiseleyo kunokukhokelela kumanzi kunye nongcoliseko lomhlaba. Kungoko, ulawulo olungqongqo kunye neendlela ezifanelekileyo zokulahla inkunkuma zibalulekile ngexesha lemveliso kunye nokusetyenziswa.
