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.

Puas yog ntsev daws acidic lossis yooj yim?
PH ntawm ntsev tov. Lub pH ntawm cov tshuaj ntsev yog txiav txim siab los ntawm tus txheeb ze lub zog ntawm nws ?conjugated acid-base khub. Cov ntsev tuaj yeem yog acidic, nruab nrab, lossis yooj yim. Cov ntsev uas tsim los ntawm cov kua qaub uas muaj zog thiab lub hauv paus tsis muaj zog yog cov ntsev ntsev, xws li ammonium chloride (NH4Cl)
Puas yog Ag + acidic lossis yooj yim?
Kauj Ruam 3: Nws txhais tau hais tias Ag + yog ua raws li lewis acid los ntawm kev txais ib khub ntawm electron los ntawm NH3 thiab NH3 yog ua raws li lub hauv paus los ntawm pub ib khub ntawm electrons
Puas yog chlorine yooj yim lossis acidic?
Chlorine gas bleached daim ntawv litmus. Qhov no yog vim muaj cov hypochlorite ions. Yog li, thaum chlorine (txhua daim ntawv) ntxiv rau hauv dej, cov kua qaub tsis muaj zog hu ua Hypochlorousacid yog tsim. Nws yog cov kua qaub no, tsis yog cov tshuaj chlorine, uas muab dej nws lub peev xwm los oxidize thiab tua kab mob
Yuav ua li cas koj txiav txim siab yog hais tias ib yam khoom yog acidic los yog yooj yim?
Txhawm rau txiav txim siab seb cov khoom puas yog acid orabase, suav cov hydrogens ntawm txhua yam khoom ua ntej thiab tom qab cov tshuaj tiv thaiv. Yog hais tias tus naj npawb ntawm hydrogenshas txo cov tshuaj yog cov kua qaub (donates hydrogen ions). Yog tias tus naj npawb ntawm hydrogens tau nce ntxiv tias cov khoom yog lub hauv paus ( lees txais hydrogenions )
Vim li cas cov lus ntsev tau yooj yim yaj hauv dej?
Lub rooj ntsev yaj nyob rau hauv dej vim hais tias cov polar dej molecules nyiam ob qho tib si zoo nqi sodium ions thiab cov tsis zoo chloride ions. Lwm cov ntsev yaj hauv dej, ib yam nkaus, tab sis qee qhov lawv yaj yooj yim dua lwm tus
