Kev siv phosphoric acid hauv kev ua liaj ua teb

Qhia

Phosphoric acid yog ib qho khoom siv tshuaj ua los ntawm cov ntsiab lus hydrogen, phosphorous, thiab oxygen. Phosphoric acid tseem hu ua phosphatic (V) acid, thiab nws cov tshuaj formula yog H3PO4.Nws ib txwm pom zoo li cov kua tsis muaj xim, tab sis cov ntshiab compound yog cov xim tsis muaj xim. Cov tshuaj no muaj ntau yam kev lag luam siv, tab sis nws yog feem ntau siv nyob rau hauv chiv rau kev ua liaj ua teb sector.

85% phosphoric acid nthuav tawm nws tus kheej nyob rau hauv daim ntawv ntawm syrup, tuab tab sis tseem pourable.

Lub hauv paus conjugate ntawm cov kua qaub no yog dihydrogen phosphate anion, uas yog kev sib xyaw ntawm hydrogen thiab phosphate ions.

Phosphoric acid pab txhim kho kev noj qab haus huv thiab assimilation ntawm lwm cov as-ham xws li nitrogen thiab potassium los ntawm cov qoob loo. Tsis tas li ntawd, nws pab txhim kho cov av pH, uas yog qhov tseem ceeb rau cov nroj tsuag kev loj hlob thiab kev loj hlob.

Lwm qhov tseem ceeb ntawm kev siv phosphoric acid hauv kev ua liaj ua teb yog siv tshuaj tua kab mob. Nws ua raws li ib tug desiccant, txhais tau hais tias nws qhuav cov nroj tsuag cov ntaub so ntswg thiab cuam tshuam lawv cov haujlwm tseem ceeb. Cov neeg ua liaj ua teb siv cov cuab yeej no txhawm rau tshem tawm qhov tsis xav tau kev loj hlob hauv lawv cov teb, xws li cov nroj tsuag thiab lwm yam kab mob. Qhov no yuav pab kom cov qoob loo noj qab nyob zoo thiab muaj txiaj ntsig zoo.

Thaum kawg, phosphoric acid kuj tseem siv rau kev kho av. Nws yog ib qho kev nyab xeeb thiab muaj txiaj ntsig zoo rau neutralize alkaline av tej yam kev mob. Qhov no yuav pab txhim kho cov qauv av, uas pab txhawb kev noj zaub mov zoo dua los ntawm cov qoob loo thiab txhim kho tag nrho cov av kev noj qab haus huv.
