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
