Lewis qauv ntawm oxalic acid yog qhia hauv qab no. … Molecules uas muaj ntau tshaj ib cov kua qaub hydrogen hu ua polyprotic acids. Ib yam li ntawd, yog tias lub molecule tsuas muaj ib qho acidic hydrogen, nws hu ua monoprotic acid. Oxalic acid, H2C2O4, yog tsis muaj kua qaub.
YPuas yog oxalic acid dihydrate monoprotic lossis Diprotic?
Oxalic acid dihydrate yog khoom, diprotic acid uas tuaj yeem siv hauv chav kuaj ua tus qauv thawj. Nws cov qauv yog H2C2O4•2H2O.
YPuas yog oxalic acid yog Triprotic?
Diprotic acids, xws li sulfuric acid (H 2 SO 4), carbonic acid (H 2 CO3), hydrogen sulfide (H2S), chromic acid (H2 CrO4), thiab oxalic acid (H2C2O4) muaj ob acidic hydrogen atoms. Triprotic acids, xws li phosphoric acid (H3PO4) thiab citric acid (C6H 8O7), muaj peb.
Koj tuaj yeem qhia tau li cas yog tias cov kua qaub yog monoprotic Diprotic lossis Triprotic?
Cov no yog cov kua qaub uas tuaj yeem tsim ntau dua ib H+ ions thaum yaj hauv dej. H2CO32SO3 hu ua diprotic acids, thiab H3PO3 thiab H3 PO 4 yog hu ua triprotic acids. HF, HCl, HBr, thiab HC 2H3O2 yog piv txwv ntawm monoprotic acids. Lub dissociation ntawm polyprotic acids feem ntau tshwm sim nyob rau hauvcov kauj ruam.
YPuas yog oxalic acid yog Diprotic acid?
Piv txwv li, oxalic acid, tseem hu ua ethanedioic acid, yog diprotic, muaj ob lub proton los pub.
Pom zoo:
Puas yog ascorbic acid thiab citric acid tib yam?
Hauv kev khaws zaub mov, citric acid thiab ascorbic acid yog ob hom kua qaub siv rau ob txoj haujlwm sib txawv. Hos ob leeg yog cov kua qaub, lawv tsis zoo ib yam. … Citric acid yog acidic dua li ascorbic acid. Yog li ntawd, citric acid tau pom zoo thaum lub kaus mom txiv lws suav kom txo qis pH lossis nce acidity.
Puas yog palmitic acid yog ib qho tseem ceeb fatty acid?
Palmitic acid tsis yog ib qho tseem ceeb fatty acid vim tus me nyuam mos muaj peev xwm ntawm de novo synthesis ntawm palmitic acid ntawm qabzib. Txawm li cas los xij, nyob rau hauv tib neeg cov kua mis triglycerides, palmitic acid muaj ntau heev (20-25% ntawm tag nrho cov mis fatty acids).
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.
Puas yog isocyanuric acid tib yam li cyanuric acid?
Stabiliser yog lub npe generic muab rau kev siv cyanuric acid (tseem hu ua iso-cyanuric acid) los yog nws cov chlorinated compounds ntawm sodium dichloro-isocyanurate thiab trichloro-isocyanuric acid.. Thaum ntxiv rau lub pas dej da dej sab nraum zoov cyanuric acid bonds xoob rau chlorine kom txo nws cov degradation los ntawm UV teeb.
Nyob rau hauv titration ntawm qaug zog monoprotic acid nrog naoh lub?
Nqe Lus Nug: Thaum titrating ib qho tsis muaj zog monoprotic acid nrog NaOH ntawm 25 ° C,pH yuav ntau dua 7 ntawm qhov sib npaug ntawm qhov sib npaug ntawm qhov sib npaug, lossis stoichiometric point, ntawm cov tshuaj tiv thaiv tshuaj. yog lub ntsiab lus ntawm cov tshuaj sib npaug ntawm cov tshuaj reactants tau tov.
