Phosphoric acid, kuna waari dhexdeeda H formula 3 PO 4, sidoo kale loo yaqaan phosphoric. Xarunta xaaladaha caadiga ah waa xaalad adag oo ah xulkii. kiristaalo yar oo ah walaxda waa midab. Acid waa diyaar L. biyo, ethanol iyo qase kale organic. In gobolka adag oo dareere ah, ee u taagoo maalkii ururka of by bonds hydrogen iyo, sababtan awgeed waxaa ku urursan H3PO4 uu leeyahay ku nafwaayay ah oo kor u kacay. dhibic karaya ee 42,3 C, halka ay kor u kulaylinta in 213 C noqonayaa pyrophosphoric H acid 4 P 2 O 7.
Phosphoric acid waa elektrolytka ah xoog dhexdhexaad ah iyo sidoo kale tribasic acid, waxay iska fogeeyay stepwise in saddex tallaabo in xal aqueous.
Diyaar acid orthophosphoric badanaa cusbo ah oo dhanba ku jira macdan phosphate ah - apatite iyo fosfooraska, sarkhaansan sulfuric acid. Sidoo kale, by fuuq ee xabagta fosfooraska (V) by hydrolysis ama xarunta ah imanba - pentachloride phosphor.
Phosphoric acid waxaa ka jawaabay saldhigyada, oxides biraha, cusbada, biraha firfircoon iyo acids xoog leh. Marka la dhaqanka reaction hydroxides dhexdhexaadnimada dhacdaa, natiijada taas oo ah formation of cusbo iyo biyo. Ficil la oxides biraha sidoo kale u sameeyaan cusbo iyo biyo. Marka la dareen-celin cusbada dhaafsiga ficil qaadataa meel, kaas oo la helay markii cusbo cusub oo acid ah. falcelinta of acid orthophosphoric la amooniyam oo lacag ah (cusbo) waa fal-celin ah oo tayo leh, u ogolaanin in lagu ogaado xal ay. Subtotal - dadajin jaalaha ah - phosphate Silver (Ag 3 PO 4). Tan iyo biraha firfircoon, taas oo ka mid ah Beketova ilaa hydrogen yihiin galo dareen diidmo oo la bedelay. La macaamilka acids xoog (bleach) muujinayaa nooca ah dual (amphoteric) iyo foomamka cusbada adag - phosphoryl. Sidoo kale, xarunta la thermally giirte karaa in diphosphoric acid.
Phosphoric acid, isticmaalka kaas oo si weyn loo yahay, si ballaaran loo isticmaalo warshadaha badan. Tusaale ahaan, beeraha, gaar ahaan wax soo saarka ee Bacriminta ka kooban fosfooraska. Bacriminta noocan oo kale ah loo hagaajin karo wax soo saarka ma aha oo kaliya, laakiin sidoo kale saamayn ku wanaagsan ka kooban microbiological ciidda, ka qayb qaato horumarinta iyo kororka bakteeriyada faa'iido, iyo sidoo kale in la kordhiyo hardiness dalagyada. In warshadaha cuntada acid loo isticmaalo sida wax lugu daro cuntada E 338, kaas oo ku jira in qadar yar oo Pomelos, sharoobada iyo cabitaanka kaarboonta leh. Waa sababta oo ah waxa ku jira acid phosphoric oo qaarna in cabitaanka marka isticmaalka xad-dhaafka ah waxay dhacdaa burburka ilkaha. Hantidaan waxaa debciyaan dhaldhalaalka iliga iyo dentin ayaa la isticmaalay by ilkaha. Tusaale ahaan, acid phosphoric kooban Jinka gaar ah waxaa laga codsadaa in ilig ka hor buuxintii waxaa ka mid ah oo ku kordhinaya demineralization unugyada. walaxda loo isticmaalaa daaweynta abuur iyo abuuritaanka rinjiga qoryo aan guban kara iyo varnishes iyo qalabka dhismaha (non-ololi kara xumbo phosphate fosfodrevesnye saxan). Si firfircoon loo isticmaalaa in brazing copper, biraha ferrous, ahama sida nadiifiye oo ka dusha sare ee oxides biraha kala duwan ka saaraysaa. Sidoo kale loo isticmaalaa in descaling, saabuunta iyo biology kelli.
Phosphoric acid waxaa laga helaa isticmaalka firfircoon oo kala duwan ay sabab u tahay sifooyinka ay physicochemical iyo diyaarinta kharash yar.
