Phosphoric acid

I-asidi ye-Phosphoric Umfanekiso obonakalayo

inkcazelo emfutshane:

A acid inorganic eqhelekileyo, phosphoric acid akukho lula volatilize, akukho lula ukubola, phantse akukho oxidation, nge acid commonness, i ternary buthathaka acid, acidity yayo buthathaka ngaphezu hydrochloric acid, sulfuric acid, nitric acid, kodwa yomelele ngaphezu acetic. acid, boric acid, etc. asidi phosphoric lula deliquified emoyeni, kunye nobushushu uya kuphulukana namanzi ukufumana pyrophosphoric acid, kwaye ke ngakumbi ukulahlekelwa amanzi ukufumana 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.
