A qaug zog acid yog ib kua qaub uas ib nrab dissociates rau hauv nws ions nyob rau hauv ib tug aqueous tov los yog dej. Piv txwv li, a muaj zog acid tag nrho dissociates rau hauv nws cov ions hauv dej. Nyob rau tib lub concentration, tsis muaj zog acids muaj pH ntau dua muaj zog acids.
Ib yam li ib tug yuav nug, dab tsi txiav txim siab lub zog ntawm cov kua qaub?
Ib kua qaub tau txais nws cov yam ntxwv los ntawm hydrogen atoms ntawm nws cov molecules. Muaj zog kua qaub muaj zog khi hydrogen atoms, thiab cov molecules yooj yim cais los ntawm lawv nyob rau hauv kev daws. Muaj pes tsawg ntawm cov atoms hydrogen dissociate thiab tsim hydrogen ions txiav txim siab lub zog ntawm cov kua qaub.
Tsis tas li ntawd, 7 lub zog acids yog dab tsi? Muaj 7 lub zog acids: chloric acid, hydrobromic acid , hydrochloric acid, hydroiodic acid, nitric acid, perchloric acid, thiab sulfuric acid. Ua ib feem ntawm cov npe ntawm cov kua qaub uas muaj zog tsis muaj qhov qhia txog qhov txaus ntshai lossis ua rau cov kua qaub puas.
Tom qab ntawd, lo lus nug yog, puas yog acetic acid muaj zog lossis tsis muaj zog?
Acetic acid yog a qaug zog acid vim nws tsis yog ib muaj zog acid uas muaj cov ntsiab lus tshwj xeeb hauv chemistry: Muaj zog acids tag nrho dissociate nyob rau hauv aqeous tov, uas yog, tag nrho lawv H + tawm hauv dej. H + tseem hu ua proton vim hydrogen tsis muaj electron yog qhov tseem ceeb ntawm proton.
LiOH puas muaj zog lossis qaug zog?
Txawm hais tias nyob rau hauv cov ntaub ntawv ntawm lithium, ntawm ib sab peb muaj ib tug loj electron nplua nuj hydroxide ion thiab ntawm qhov tod tes yog qhov me me, densly packed electron tsis muaj lithium ion nrog siab polarisability ua rau ib tug me ntsis covalent molecule thiab li no ib tug qis coefficient ntawm dissociation., LiOH yog qhov twg hauv
Pom zoo:
Puas yog HClO muaj zog lossis tsis muaj zog?
HClO yog ib qho kua qaub raws li nws muaj cov proton uas nws tso tawm tab sis nws yog ib qho tsis muaj zog acid vim nws tsis yog ib qho acidamoung cov npe ntawm cov kua qaub muaj zog
Yuav ua li cas tshwm sim thaum koj sib tov ib tug muaj zog acid nrog ib tug tsis muaj zog puag?
Hom 2: thaum muaj zog acid / base reacts nrog lub hauv paus tsis muaj zog / acid yog hydronium thiab hydroxyl ions tam sim no nyob rau hauv sib npaug amt ces ntsev thiab dej yog tsim thiab lub zog tso tawm uas tsawg tshaj li 57 kj / mole vim lub dissociation ntawm lub tsis muaj zog acid / puag uas feem ntau endothermic
Puas muaj zog acid thiab qaug zog hauv paus ua rau tsis muaj?
Raws li koj tau pom hauv kev suav cov pH ntawm cov kev daws teeb meem, tsuas yog ib qho me me ntawm cov kua qaub uas muaj zog heev yog qhov tsim nyog los hloov pH. Ib qho tsis yog tsuas yog sib xyaw ntawm cov kua qaub tsis muaj zog thiab nws lub hauv paus conjugate lossis lub hauv paus tsis muaj zog thiab nws cov conjugate acid. Buffers ua hauj lwm los ntawm reacting nrog ib qho ntxiv acid los yog hauv paus tswj pH
Thaum twg muaj zog acid yog titrated nrog lub hauv paus tsis muaj zog?
Titration ntawm lub hauv paus tsis muaj zog nrog lub zog acid. Nyob rau hauv ib qho tsis muaj zog hauv paus-muaj zog acid titration, cov kua qaub thiab lub hauv paus yuav hnov mob los tsim cov kua qaub. Lub conjugate acid yuav raug tsim thaum lub sij hawm titration, uas tom qab ntawd reacts nrog dej los tsim hydronium ions. Qhov no ua rau muaj kev daws teeb meem nrog pH qis dua 7
Puas yog acid rau dej lossis dej rau acid?
Thaum tshav kub kub tau tso tawm ntau heev uas cov tshuaj yuav ua rau kub hnyiab heev, txaws concentrated acid tawm ntawm lub thawv! Yog tias koj ntxiv cov kua qaub rau hauv dej, cov tshuaj uas cov ntaub ntawv yog diluted heev thiab qhov me me ntawm cov cua sov tso tawm tsis txaus rau vaporize thiab spatter nws. Yog li Ib txwm Ntxiv Acid rau dej, thiab tsis txhob thim rov qab
