Ib tug kua qaub yog ib yam khoom uas pub hydrogen ions Vim li no, thaum cov kua qaub yaj hauv dej, qhov sib npaug ntawm hydrogen ions thiab hydroxide ions hydroxide ions Hydroxide yog diatomic anion nrog tshuaj formula OH - Nws muaj cov pa oxygen thiab hydrogen atom tuav ua ke los ntawm ib qho kev sib cog lus, thiab nqa cov hluav taws xob tsis zoo. Nws yog ib qho tseem ceeb tab sis feem ntau me me ntawm cov dej. Nws ua haujlwm raws li lub hauv paus, ligand, nucleophile, thiab catalyst. https://en.wikipedia.org › wiki › Hydroxide

yog hloov. Tam sim no muaj hydrogen ions ntau dua li hydroxide ions hauv cov tshuaj. Cov tshuaj no yog acidic.
Dab tsi ua rau cov kua qaub ua kua qaub GCSE?
Thaum ib yam dab tsi yog acidic, txhais tau hais tias muaj H + ions tso tawm thaum cov tshuaj yaj hauv dejThaum ib yam dab tsi yog alkaline, nws txhais tau tias muaj OH- ions tso tawm thaum lub cov khoom yog yaj nyob rau hauv dej. Tus nqi ntawm ions hauv cov kua qaub los yog alkali txiav txim siab nws muaj zog npaum li cas.
Yuav ua li cas txiav txim siab tias qee yam yog kua qaub?
Kev siv pH nplaiyog ib txoj hauv kev ntawm kev txiav txim siab ntau npaum li cas acidic. Yog tias pH ntawm kev daws tsawg dua 7, nws yog acidic. Yog tias pH yog 7, qhov kev daws teeb meem yog nruab nrab thiab yog tias pH ntau dua 7, cov tshuaj yog qhov yooj yim.
Dab tsi ua rau cov kua qaub acidic thiab lub hauv paus yooj yim?
Ib Arrhenius acid nce qhov concentration ntawm hydrogen (H+) ions hauv cov tshuaj aqueous, thaum lub hauv paus Arrhenius nce qhov concentration ntawm hydroxide (OH–) ions hauv cov tshuaj aqueous.
Dab tsi ua rau acidic?
Yuav kom acidic ces, ib yam khoom yuav tsum muaj hydrogen, nyob rau hauv daim ntawv uas tso rau hauv dej. Ntawm qhov tod tes, cov tshuaj xws li hydrochloric acid, HCl, yog tuav ua ke los ntawm cov polar ionic bonds thiab thaum muab tso rau hauv dej hydrogen yuav tawg mus rau hydrogen ions, ua rau cov kua qaub.
