Phosphoric acid, tseem hu ua orthophosphoric acid lossis phosphoric(V) acid, yog cov kua qaub tsis muaj zog nrog cov tshuaj formula H ₃PO ₄. Cov khoom xyaw ntshiab yog cov xim tsis muaj xim. Tag nrho peb cov hydrogens yog acidic rau qhov sib txawv thiab tuaj yeem ploj ntawm cov molecule li H⁺ ions.
Nws yog orthophosphoric acid?
Phosphoric Acid yog cov kua qaub tsis muaj zog nrog cov tshuaj formula H3PO4. Phosphoric Acid yog cov kua qaub uas muaj plaub atoms ntawm oxygen, ib atom ntawm phosphorus, thiab peb atoms ntawm hydrogen. Nws tseem hu ua phosphoric (V) acid lossis orthophosphoric acid. Nws muaj nyob hauv cov hniav thiab pob txha thiab pab hauv cov txheej txheem metabolic.
N yog dab tsi ntawm orthophosphoric acid?
Orthophosphoric acid yog tribasic acid; nws muaj peb qhov hloov tau hydrogen ions ib mole. Rau cov kua qaub n-factor yog qhov tseem ceeb nws yog txhais los ntawm tus naj npawb ntawm hydrogen ions hloov. n-factor rau orthophosphoric acid yog 3.
Yuav suav li cas n Factor?
Xaiv n-factor ntawm ntsev ntawm hom, peb noj ib mole ntawm cov reactant thiab nrhiav tus naj npawb ntawm mole ntawm lub caij uas nws oxidation lub xeev hloov. Qhov no yog sib npaug nrog lub xeev oxidation ntawm cov khoom nyob rau hauv lub reactant, uas muab peb tag nrho oxidation lub xeev ntawm lub caij nyob rau hauv lub reactant.
N yam ntawm H 3 PO 4 yog dab tsi?
ntawm H + ions nws tsim tawm ntawm kev sib cais ntawm cov kua qaub yog 3. Li no tus n-factor rau phosphoric acid H3PO4 yog3.

Formula rau sulfonic acid?
Sulfonic acid, sulfonic kuj sau sulfonic, ib chav kawm ntawm cov organic acids uas muaj leej faj thiab muaj cov qauv dav RSO 3 H , nyob rau hauv uas R yog ib pawg organic combining. tshuaj lub npe so3h yog dab tsi? A sulfonic acid (los yog sulfonic acid) yog hais txog ib tug tswv cuab ntawm chav kawm ntawm organosulfur tebchaw nrog cov qauv dav dav R−S(=O) 2 -OH, qhov twg R yog cov organic alkyl lossis aryl pawg thiab S(=O) 2(OH) pab pawg sulfonyl hydroxide.
Formula rau butyric acid?
Butyric acid, tseem paub nyob rau hauv lub npe systematic butanoic acid, yog ib tug ncaj-chain alkyl carboxylic acid nrog cov tshuaj formula CH₃CH₂CH₂CO₂H. Nws yog oily, colorless kua nrog ib tug unpleasant tsw. Isobutyric acid yog ib qho isomer.
Yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau pom kev pom?
Txawm li cas los xij, corneal collagen cross-linking - cov txheej txheem qib siab tau pom zoo los ntawm US Food and Drug Administration (FDA) hauv xyoo 2016 - tuaj yeem txhim kho qhov pom kev hauv cov neeg mob txhua hnub nyoog. Corneal collagen cross-linking (CXL) tsis yog kho rau keratoconus, tab sis nws tuaj yeem pab tiv thaiv tus mob kom tsis txhob mob hnyav.
Puas yog orthophosphoric acid tib yam li phosphoric acid?
Phosphoric acid, tseem hu ua orthophosphoric acid lossis phosphoric (V) acid, yogtsis muaj kua qaubnrog cov tshuaj formula H3PO4. Lub npe phosphoric acid yog dab tsi? Orthophosphoric acid, H3PO4, feem ntau hu ua yooj yim phosphoric acid.
Thaum orthophosphoric acid yog cua sov ntawm cov khoom tseem ceeb tsim yog?
Ib kauj ruam los ntawm cov lus teb: Orthophosphoric acid lossis H3PO4 thaum rhuab mus rau qhov kub ntawm 250 ∘ C yields pyrophosphoric acid thiab dej raws li cov khoom ntawm nws cov tshuaj tiv thaiv. Thaum orthophosphoric acid yog cua sov ntawm 240 degrees Celsius cov khoom tseem ceeb tsim yog?
