Yog li qhov pib thiab tus cwj pwm tseem ceeb yog lub sijhawm sib txawv. Lub hauv paus ntawm cov kua qaub yog tus naj npawb ntawm H + ions nws tuaj yeem muab tso rau hauv kev daws teeb meem. Piv txwv li: qhov yooj yim ntawm HCl yog 1. Tus cwj pwm tseem ceeb ntawm qhov sib xyaw yog nws lub peev xwm los ua lub hauv paus.
Puas yog qhov pib thiab lub zog yooj yim ib yam?
Lub hauv paus ntawm cov kua qaub yog cov naj npawb ntawm hydrogen ions, uas tuaj yeem tsim los ntawm ib qho molecule ntawm cov kua qaub. Cov lus hauv qab no qhia qee cov acids thiab lawv cov hauv paus. Lub zog tseem ceeb ntawm qhov tod tes yog yuav ua li cas lub hauv paus tsim OH- ions sai sai thaum yaj hauv dej.
Dab tsi yog qhov sib txawv ntawm qhov pib thiab lub hauv paus?
The acidity los yog qhov pib ntawm cov compound yog ntsuas raws li pH ntawm cov compound.… Lub acidity ntawm lub hauv paus yog tus naj npawb ntawm hydroxyl ions uas lub hauv paus molecule tuaj yeem tsim nyob rau hauv cov tshuaj aqueous. Lub hauv paus ntawm cov kua qaub yog cov naj npawb ntawm hydronium ions uas lub compound tuaj yeem tsim nyob rau hauv cov tshuaj aqueous.
Puas txo tus cwj pwm thiab qhov pib zoo ib yam?
Txo tus cwj pwm tsis muaj dab tsitab sis qhov nyiam ntawm cov tshuaj txo qis lwm yam tshuaj thiab qhov pib yog li cas lub compound tuaj yeem muab hudrogen atom lossis electrons yooj yim.
Pab hauv paus yog dab tsi?
Basicity yog hais txog lub hauv paus lub peev xwm los txais ib qho proton. Hydroxide ion (HO-) lees txais cov proton yooj yim, thiab yog qhov yooj yim heev. Dej tsis lees txais ib qho proton raws li hydroxide ion ua; dej yog weakly yooj yim. Hydroxide ion yog lub hauv paus muaj zog Bronsted thiab zoo nucleophile.
