Orthophosphoric acid waa phosphoric acid oo ka kooban hal fosfo-oxygen tetrahedron.Fosfooraska acid, P atomku waa sp3 hybrid, saddex orbitals hybrid waxay sameeyaan saddex σ bonds oo leh atamka oksijiinta, iyo dammaanadda PO kale waxay ka kooban tahay hal σ bond ka fosfooraska ilaa oksijiinta iyo laba dp bonds oo ka yimaada oksijiinta ilaa fosfooraska.Isku-xidhka σ waxa la sameeyaa marka lammaane keli ah oo elektaroonik ah oo atamka fosfooraska ah isku xidho orbital madhan oo atamka ogsijiinta ah.Xidhiidhka d←p waxa uu samaysma iyada oo la isku dhejiyo py iyo pz-lammaanaha kaliya ee atamka ogsijiinta oo leh dxz iyo dyz orbitals of fosfooraska.

Isticmaalka Alaabta

Isticmaalka ugu weyn

Beeraha:Phosphoric acid waa walxo ceeriin ah oo loogu talagalay soo saarista bacrimiyeyaasha fosfateetka muhiimka ah (superphosphate, potassium dihydrogen phosphate, iwm.), sidoo kale waa walxo ceeriin ah oo loogu talagalay soo saarista nafaqooyinka quudinta (calcium dihydrogen phosphate).

Warshadaha:Phosphoric acid waa walxo kiimiko ah oo ceeriin ah oo muhiim ah.Shaqadeeda ugu muhiimsan waa sida soo socota:

1, daawee dusha birta, soo saar filim fosfateed aan milmi karin oogada birta si ay birta uga ilaaliso daxalka.

2, lagu qaso nitric acid sida polishing kiimikaad si loo hagaajiyo dhamaadka dusha birta.

3, wax soo saarka sahayda dhaqida, sunta cayayaanka ceeriin phosphate ester.

4, wax soo saarka fosfooraska ka kooban alaabta ceeriin ee ololka.

Cuntada:Phosphoric acid waa mid ka mid ah waxyaabaha lagu daro cuntada, cuntada sida wakiilka dhanaan, nafaqada khamiirka, koollada waxaa ku jira fosfooraska acid.Phosphate sidoo kale waa cunto lagu daro muhiim ah waxaana loo isticmaali karaa kobciye nafaqo.

Daawo:Phosphoric acid waxaa loo isticmaali karaa in lagu sameeyo dawooyinka fosfooraska ku jira, sida sodium glycerophosphate.
