Phosphoric acid

Cov lus piav qhia luv luv:

Ib qho kev sib xyaw ua ke acid, phosphoric acid tsis yooj yim rau kev loj hlob, yog muaj zog tshaj li acidatic acid, thiab cua sov yuav poob dej kom tau pyophosphoric Acid, thiab tom qab ntawd tom qab ntawd yuav poob dej kom tau metaphosphate.

Orthophosphoric acid yog phosphoric acid tsim los ntawm ib phosphoto-oxygen tetrahedron. Hauv phosphoric acid, lub p atfl yog sp3 hybrid, peb hybrid los ntawm phosphorus mus rau ntawm phosphorus mus rau oxygen rau oxygen los ntawm oxygen rau phosphorus. Ib txoj kev sib tsoo yog tsim thaum ib leeg siv cov hluav taws xob ntawm cov hluav taws xob ntawm cov tshuaj hluav taws xob atom cov neeg ua haujlwm kom ib qho khoob ntawm cov pa otom. Lub D ← P daim ntawv cog lus yog tsim los ntawm overlapping PY thiab PZ Lone ua ke ntawm oxygen atoms nrog rau dxz thiab dyz npliag ntawm phosphorus atoms.

Lub ntsiab siv

Ua Liaj Ua Teb:Phosphoric acid yog cov khoom siv raw rau kev tsim cov khoom tseem ceeb ntawm cov khoom siv pub rau cov khoom noj khoom haus rau cov khoom noj khoom haus (calcium dihydrogen phosphate).

Kev Lag Luam:Phosphoric acid yog ib qho tseem ceeb rau cov khoom siv raw. Nws cov haujlwm tseem ceeb muaj raws li hauv qab no:

1, kho cov hlau saum npoo av, tsim cov yeeb yaj kiab phosplele phosphate rau ntawm cov hlau saum npoo los tiv thaiv cov hlau los ntawm kev xeb.

2, tov nrog nitric acid ua tshuaj lom neeg polish los txhim kho qhov tiav ntawm cov hlau nto.

3, kev tsim cov khoom ntxuav, tshuaj tua kab, cov khoom siv tshuaj tua kab phosphte ester.

4, zus tau tej phosphorus-muaj nplaim retardant raw khoom.

Khoom Noj:Phosphoric acid yog ib qho ntawm cov zaub mov muaj ntxiv, hauv cov zaub mov ua ib tus qaub rau tus neeg sawv cev, cov poov xab, cafa muaj phosphoric acid. Phosphate kuj yog cov zaub mov tseem ceeb ntxiv thiab tuaj yeem siv ua cov khoom noj muaj txiaj ntsig zoo.

Tshuaj kho mob:Phosphoric acid tuaj yeem siv los ua kom phosphorus-muaj cov tshuaj, xws li sodium glycerophosphate.
