Yog hais tias acid tsis tau teev nyob ntawm no, nws yog ib tsis muaj zog acid . Nws tuaj yeem yog 1% ionized lossis 99% ionized, tab sis nws tseem raug cais raws li a qaug zog acid . Ib qho kua qaub uas dissociates 100% rau hauv ions yog hu ua a muaj zog acid . Yog nws tsis dissociate 100%, nws yog a qaug zog acid.

Ua li no, koj yuav txiav txim siab li cas lub zog ntawm cov kua qaub?

Daim ntawv cog lus lub zog ntawm ib kua qaub Feem ntau nyob ntawm qhov loj ntawm 'A' atom: qhov me me ntawm 'A' atom, qhov muaj zog ntawm H-A daim ntawv cog lus. Thaum nkag mus rau hauv kab hauv Lub Sijhawm Sijhawm (saib daim duab hauv qab), cov atoms tau loj dua li qhov lub zog ntawm cov bonds tau qaug zog, uas txhais tau hais tias cov acids tau muaj zog.

Ib yam li ntawd, koj ua li cas txiav txim siab lub hauv paus muaj zog? A lub hauv paus muaj zog yog ib yam dab tsi zoo li sodium hydroxideor potassium hydroxide uas yog tag nrho ionic. Koj tuaj yeem xav txog cov khoom sib xyaw ua 100% faib ua hlau ions thiab hydroxide ionsin tov. Txhua mole ntawm sodium hydroxide dissolves kom muab ib moleof hydroxide ions hauv kev daws.

Yog li ntawd, dab tsi ua rau acid lossis lub hauv paus muaj zog?

Acids lossis bases nrog muaj zog bonds muaj feem ntau raws li cov molecules hauv kev daws teeb meem thiab hu ua "tsis muaj zog" acids los yog bases . Acids lossis bases nrog tsis muaj zog bonds yooj yim dissociate rau hauv ions thiab hu ua " muaj zog " acids orbases.

LiOH puas muaj zog lossis qaug zog?

Classifying Electrolytes

Muaj zog Electrolytes muaj zog cov kua qaub HCl, HBr, HI, HNO3, HClO3, HClO4, thiab H2YOG4
lub hauv paus muaj zog NaOH, KOH, LiOH, Ba(OH)2, thiab Ca(OH)2
ntsev NaCl, KBr, MgCl2, thiab ntau, ntau ntau
Electrolytes tsis muaj zog
tsis muaj zog acids HF, HC2H3O2 (acetic acid), H2CO3 (carbonic acid), H3PO4 (phosphoric acid), thiab lwm yam
