Phosphoric acid

Kufotokozera mwachidule:

A wamba inorganic asidi, asidi phosphoric n'zosavuta volatilize, zosavuta kuwola, pafupifupi palibe makutidwe ndi okosijeni, ndi asidi commonness, ndi ternary ofooka asidi, acidity ake ndi ofooka kuposa hydrochloric acid, sulfuric acid, nitric acid, koma wamphamvu kuposa acetic. asidi, asidi boric, etc. Phosphoric asidi mosavuta deliquified mu mlengalenga, ndi kutentha adzataya madzi kuti pyrophosphoric asidi, ndiyeno zina kutaya madzi kupeza metaphosphate.

Orthophosphoric acid ndi phosphoric acid yopangidwa ndi tetrahedron imodzi ya phospho-oxygen.Mu asidi wa phosphoric, atomu ya P ndi sp3 wosakanizidwa, ma orbitals atatu osakanizidwa amapanga ma bond atatu σ ndi atomu ya okosijeni, ndipo chomangira china cha PO chimapangidwa ndi chomangira chimodzi cha σ kuchokera ku phosphorous kupita ku okosijeni ndi zomangira ziwiri za dp kuchokera ku okosijeni kupita ku phosphorous.Chomangira cha σ chimapangidwa pamene ma elekitironi awiri kuchokera ku atomu ya phosphorous amalumikizana ndi orbital yopanda kanthu ya atomu ya okosijeni.Chomangira cha d←p chimapangidwa podutsana maatomu a py ndi pz amodzi a maatomu okosijeni ndi dxz ndi dyz ma orbital opanda maatomu a phosphorous.

Kugwiritsa Ntchito Mankhwala

Kugwiritsa ntchito kwakukulu

Agriculture:Phosphoric acid ndi zopangira zopangira feteleza wofunikira wa phosphate (superphosphate, potaziyamu dihydrogen phosphate, etc.), komanso ndi zopangira zopangira chakudya chamagulu (calcium dihydrogen phosphate).

Makampani:Phosphoric acid ndi chinthu chofunikira kwambiri chamankhwala.Ntchito zake zazikulu ndi izi:

1, kuchitira zitsulo pamwamba, kupanga insoluble mankwala filimu pamwamba zitsulo kuteteza zitsulo dzimbiri.

2, wothira nitric acid ngati kupukuta kwamankhwala kuti apititse patsogolo kutha kwachitsulo.

3, kupanga zinthu zochapira, mankhwala ophera tizilombo phosphate ester.

4, kupanga phosphorous munali flame retardant zipangizo.

Chakudya:Phosphoric acid ndi chimodzi mwazowonjezera chakudya, mu chakudya monga wowawasa wothandizira, yisiti zakudya, kola lili phosphoric acid.Phosphate ndi gawo lofunikira lazakudya ndipo litha kugwiritsidwa ntchito ngati chowonjezera michere.

Mankhwala:Phosphoric acid angagwiritsidwe ntchito kupanga mankhwala okhala ndi phosphorous, monga sodium glycerophosphate.
