Phosphoric acid

I-asidi ye-Phosphoric Umfanekiso obonakalayo

inkcazelo emfutshane:

A acid inorganic eqhelekileyo, asidi phosphoric akukho lula volatilize, akukho lula ukubola, phantse akukho oxidation, nge acid commonness, i ternary buthathaka acid, acidity yayo buthathaka ngaphezu hydrochloric acid, sulfuric acid, asidi nitric, kodwa yomelele ngaphezu acetic, boric acid, njl. ngakumbi ulahlekelwa ngamanzi ukuze ufumane i-metaphosphate.

I-Orthophosphoric acid yi-asidi ye-phosphoric eyenziwe yi-tetrahedron enye ye-phospho-oxygen. Kwi-asidi ye-phosphoric, i-athomu ye-P yi-sp3 hybrid, ii-orbitals ezintathu ezixubileyo zenza iibhondi ezintathu ze-σ ne-athomu ye-oxygen, kwaye enye ibhondi ye-PO yenziwe ngebhondi enye ye-σ ukusuka kwi-phosphorus ukuya kwi-oksijeni kunye neebhondi ezimbini ze-dp ukusuka kwi-oksijeni ukuya kwi-phosphorus. Ibhondi engu-σ yenziwa xa iperi enye yee-electron ukusuka kwi-athomu ye-phosphorus ilungelelanisa kwi-orbital engenanto ye-athomu ye-oxygen. Ibhondi ye-d←p yenziwa ngokugqithelana phezu kwe-py kunye ne-pz izibini ezilodwa zee-athom ze-oxygen kunye ne-dxz kunye ne-dyz engenanto ye-orbitals ye-athom ye-phosphorus.

Ukusetyenziswa kweMveliso

Usetyenziso oluphambili

Ezolimo: I-asidi ye-Phosphoric yimathiriyeli ekrwada yokuveliswa kwezichumisi ze-phosphate ezibalulekileyo (i-superphosphate, i-potassium dihydrogen phosphate, njl.), kwaye iphinde ibe yimathiriyeli ekrwada yokuvelisa izondlo zokutya (i-calcium dihydrogen phosphate).

Ishishini: I-asidi ye-Phosphoric yimathiriyeli ebalulekileyo yekhemikhali ekrwada. Imisebenzi yayo ephambili yile ilandelayo:

1, phatha umphezulu wesinyithi, uvelise ifilimu ye-phosphate enganyibilikiyo kumphezulu wesinyithi ukukhusela isinyithi kwi-corrosion.

I-2, ixutywe ne-nitric acid njengepolishi yekhemikhali ukuphucula ukugqitywa kwendawo yesinyithi.

3, ukuveliswa kwempahla yokuhlamba, i-pesticide ekrwada i-phosphate ester.

4, ukuveliswa kwe-phosphorus-equlethe i-flame retardant ekrwada.

Ukutya: I-asidi ye-Phosphoric yenye yezongezo zokutya, ekutyeni njenge-agent emuncu, isondlo semvubelo, i-cola iqukethe i-phosphoric acid. I-Phosphate ikwayinto ebalulekileyo yokutya kwaye ingasetyenziswa njengesiphuculi sezondlo.

Iyeza: Iasidi yephosphoric ingasetyenziselwa ukwenza amachiza ane-phosphorus, afana ne-sodium glycerophosphate.
