Cov khoom ntawm Rooj ntsev : Rooj ntsev yog cov khoom tsim los ntawm neutralization ntawm ib qho kua qaub los ntawm a puag . Yog li nws tsis yog Acid tsis yog Puag . Koj tuaj yeem siv pH Scale los qhia seb nws acid los yog puag.

Hauv qhov no, yog cov lus ntsev alkaline lossis acidic?

Cov tshuaj chloride los ntawm hydrochloric kua qaub Hauv sodium chloride tsis hydrolyze, tab sis, yog li sodium chloride tsis yog qhov yooj yim. Qhov txawv ntawm ib qho yooj yim ntsev thiab alkali yog hais tias alkali yog cov soluble hydroxide compound ntawm alkali hlau los yog ib qho alkaline ntiaj teb hlau.

Qhov thib ob, puas muaj kua qaub hauv ntsev? Acid ntsev . Acid ntsev yog ib chav kawm ntsev uas tsim ib acidic tshuaj tom qab yaj nyob rau hauv ib qho hnyav. Nws tsim ua ib yam khoom muaj hluav taws xob ntau dua li cov kuab tshuaj ntshiab. Ib acidic daws tsim los ntawm acid ntsev yog ua thaum lub sij hawm ib nrab neutralization ntawm diprotic los yog polyprotic kua qaub.

Kuj paub, pH qib ntsev yog dab tsi?

Qhov no yog vim li cas NaCl yog qhov nruab nrab ntsev . Hauv General: Ntsev muaj halides (tshwj tsis yog F-) thiab alkaline hlau (tshwj tsis yog Be2+) yuav dissociate rau spectator ions. Ntsev uas yog los ntawm cov hauv paus muaj zog thiab tsis muaj zog acids ua hydrolyze, uas muab rau nws pH ntau dua 7.

Puas ntsev ua dej acidic?

Acid ntsev Ntxiv ib qho yooj yim ntsev zoo li ammonium chloride (NH4Cl) rau dej tsim cov tshuaj tiv thaiv uas ammonium ion (NH4 +) ua ke nrog dej los tsim ib hydronium atom (H3O+), uas yog ib qho kua qaub vim nws tso hydrogen. Acid ntsev ua dej ntau acidic.
