Phosphoric acid

piav qhia luv luv:

Ib qho inorganic acid, phosphoric acid tsis yooj yim rau volatilize, tsis yooj yim rau decompose, yuav luag tsis muaj oxidation, nrog acid commonness, yog ib tug ternary tsis muaj zog acid, nws acidity yog weaker dua hydrochloric acid, sulfuric acid, nitric acid, tab sis muaj zog tshaj acetic. acid, boric acid, thiab lwm yam phosphoric acid yog yooj yim deliquified nyob rau hauv cov huab cua, thiab tshav kub yuav poob dej kom tau pyrophosphoric acid, thiab ces ntxiv poob dej kom tau metaphosphate.

(Scope ntawm daim ntawv thov siv 'cov khoom siv')

Orthophosphoric acid yog phosphoric acid tsim los ntawm ib qho phospho-oxygen tetrahedron.Nyob rau hauv phosphoric acid, P atom yog sp3 hybrid, peb hybrid orbitals tsim peb σ bonds nrog oxygen atom, thiab lwm yam PO daim ntawv cog lus yog tsim los ntawm ib tug σ daim ntawv cog lus los ntawm phosphorus rau oxygen thiab ob dp bonds ntawm oxygen mus rau phosphorus.Ib daim ntawv cog lus σ yog tsim thaum ib leeg ib khub ntawm electrons los ntawm phosphorus atom ua haujlwm rau ib qho chaw khoob ntawm ib qho atom oxygen.d←p daim ntawv cog lus yog tsim los ntawm kev sib tshooj ntawm py thiab pz ib leeg khub ntawm oxygen atoms nrog dxz thiab dyz khoob orbitals ntawm phosphorus atoms.

Khoom siv

Kev siv tseem ceeb

Ua liaj ua teb:Phosphoric acid yog raw khoom rau zus tau tej cov phosphate chiv tseem ceeb (superphosphate, poov tshuaj dihydrogen phosphate, thiab lwm yam), thiab kuj yog ib tug raw khoom rau zus tau tej cov as-ham (calcium dihydrogen phosphate).

Kev lag luam:Phosphoric acid yog ib qho tseem ceeb tshuaj raw khoom.Nws lub luag haujlwm tseem ceeb yog raws li hauv qab no:

1, kho cov hlau nto, tsim cov phosphate zaj duab xis insoluble ntawm cov hlau nto los tiv thaiv cov hlau los ntawm corrosion.

2, sib xyaw nrog nitric acid ua cov tshuaj txhuam hniav txhawm rau txhim kho qhov tiav ntawm cov hlau nto.

3, kev tsim cov khoom siv ntxhua khaub ncaws, tshuaj tua kab raw khoom phosphate ester.

4, kev tsim cov phosphorus-muaj cov nplaim hluav taws kub retardant raw khoom.

Khoom noj khoom haus:Phosphoric acid yog ib qho ntawm cov khoom noj khoom haus additives, nyob rau hauv cov zaub mov raws li ib tug qaub neeg sawv cev, poov xab khoom noj khoom haus, cola muaj phosphoric acid.Phosphate kuj yog ib qho khoom noj khoom haus tseem ceeb thiab tuaj yeem siv los ua cov khoom noj ntxiv.

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