Lub zog ntawm daim ntawv cog lus muaj feem cuam tshuam nrog qhov ntev ntawm daim ntawv cog lus, thiab vim tias Iodine muaj lub vojvoog loj loj dua li fluorine, HI muaj qhov ntev dua, thiab yog li tsis muaj zog, daim ntawv cog lus. Cov hydrogen tshem tawm yooj yim, ua rau HI muaj zog acid.

Vim li cas HI thiaj muaj zog acid dua HCl?

HI muaj daim ntawv cog lus ntev dua HCl, ua rau nws daim ntawv cog lus qis dua. Yog li nws yooj yim dua rau HI kom poob H +, ua rau nws muaj zog acid.

Puas yog HI yog cov kua qaub tshaj plaws?

Acid Strength thiab Bond Strength

HCl, HBr, thiab HI yog tag nrho cov acids muaj zog, whereas HF yog cov kua qaub tsis muaj zog. Cov kua qaub zog nce raws li qhov kev sim pKa qhov tseem ceeb txo qis hauv qhov kev txiav txim hauv qab no: HF (pKa=3.1) < HCl (pKa=-6.0) < HBr (pKa=-9.0) < HI (pKa=-9.5).

Puas yog HI muaj zog acid dua HF?

HI yog cov kua qaub zog dua HF. Lo lus "zoo" yog ua haujlwm vim tias kev hloov pauv ntawm gaseous hydrogen atom rau aqueous proton tau raug ignored nyob rau hauv ob qho tib si analyses. Daim ntawv qhia hauv qab no teev cov ntaub ntawv rau plaub lub hydrohalic acids hauv kcal/mol.

Vim li cas HF qaug zog dua HI?

Nyob rau hauv HI iodine yog tsawg electronegative thiab nws muaj loj loj. Yog li kev sib txuas ntawm hydrogen thiab iodide tsis muaj zog. Nws yuav yooj yim faib nyob rau hauv kev sib piv ntawm HF. Vim muaj kev ywj pheej ntau dua ntawm H + ions HI muaj zog dua acid.

Vim li cas chloroacetic acid muaj zog dua?

Vim li cas chloroacetic acid muaj zog dua?

Yog li, chloroacetic acid muaj zog dua acetic acid. Teb: Vim muaj ntau cov electronegative atom Cl, electron ceev ntawm H ntawm carboxyl pawg ntawm chloroacetic acid qis dua piv rau acetic acidthiab yog li chloroacetic acid tuaj yeem tso H ntawm txoj kev yooj yim dua.

Vim li cas lub zog muaj peev xwm tsis zoo thaum lub zog txaus nyiam?

Vim li cas lub zog muaj peev xwm tsis zoo thaum lub zog txaus nyiam?

Qhov no yog tus nqi tsis zoo rau ob qho laj thawj; lub zog ua yeeb yam ntawm lawv yog qhov txaus nyiam, thiab xoom ntawm lub zog muaj peev xwm yog nyob ntawm kev sib cais tsis kawg. Qhov no yog qhov tshwm sim tsis zoo yog tias lub zog ntawm ob tus nqi txaus nyiam(lawv tawm tsam) thiab qhov zoo yog tias nws ntxub (cov nqi zoo sib xws).

Vim li cas lub zog muaj zog?

Vim li cas lub zog muaj zog?

Yog vim li cas thiaj muaj lub zog muaj zog yog vim qhov tseeb tsis tuaj yeem zam tautias hauv qab (piv txwv li ntau qhov submerged) ntawm ib qho khoom ib txwm tob hauv cov kua ntau dua li saum toj. qhov khoom. Qhov no txhais tau hais tias lub zog nce los ntawm dej yuav tsum siab dua lub zog nqes los ntawm dej.

Vim li cas hydrochloric acid thiaj li muaj zog acid?

Vim li cas hydrochloric acid thiaj li muaj zog acid?

HCl yog cov kua qaub muaj zog vim nws dissociates yuav luag tag . Los ntawm qhov sib txawv, cov kua qaub tsis muaj zog zoo li acetic acid (CH 3 COOH) tsis cuam tshuam zoo hauv dej - ntau H + ions nyob twj ywm hauv cov molecule. Hauv cov ntsiab lus:

Vim li cas qhov tseem ceeb ntawm qhov muaj zog thiab qhov tsis muaj zog yog qhov tseem ceeb?

Vim li cas qhov tseem ceeb ntawm qhov muaj zog thiab qhov tsis muaj zog yog qhov tseem ceeb?

Nws yog ib qho tseem ceeb rau qhov tseem ceeb ntawm qhov ua tau zoo thiab qhov tsis muaj zog vim qhov no pab lub tuam txhab txiav txim siab txog thaj chaw uas lawv yuav tsum tau txhim kho ntxiv rau thaj chaw uas lawv ua tau zoo hauv. Vim li cas lub zog thiab qhov tsis muaj zog tseem ceeb?
