pH ntawm ntsev tov . pH ntawm a ntsev yog txiav txim los ntawm tus txheeb ze lub zog ntawm nws ?conjugated acid- puag khub. Ntsev tuaj yeem yog acidic , nruab nrab, los yog yooj yim . Ntsev uas tsim los ntawm ib tug muaj zog acid thiab tsis muaj zog puag yog acid ntsev , zoo li ammonium chloride (NH4Cl).
Raws li txoj cai, hom ntsev twg tsim cov kua qaub?
Sodium acetate yog ib qho yooj yim ntsev ; Lub acetate ion muaj peev xwm ntawm deprotonating dej, yog li tsa lub daws pH. Acid ntsev yog qhov kev sib tham ntawm qhov yooj yim ntsev ; lawv yog tsim nyob rau hauv lub neutralization cov tshuaj tiv thaiv ntawm ib tug muaj zog kua qaub thiab lub hauv paus tsis muaj zog. Lub conjugate kua qaub ntawm lub hauv paus qaug zog ua rau ntsev acidic.
Tsis tas li ntawd, ntsev puas ua rau koj lub cev acidic? Sodium chloride, feem ntau hu ua ntsev , yog ib ntawm feem ntau cov ntxhia sib txuas pom nyob rau hauv tus ntiaj teb. Yog ntsev ntawm lub hauv paus muaj zog thiab tsis muaj zog kua qaub yog yaj nyob rau hauv dej nws yuav tsim ib tug alkaline tov, whereas, ntsev ntawm lub hauv paus tsis muaj zog thiab muaj zog kua qaub yuav form ib acidic daws.
Kuj tseem paub, uas ntsev yog acidic nyob rau hauv qhov xwm txheej?
Piv txwv li: dibasic sulfuric acid yields sodium hydrogen sulphate (NaHSO4). NaHSO4 yog cov kua qaub ntsev . Lwm cov piv txwv ntawm acid ntsev NaHSO3, Na2HPO4 and NaH2PO4.
Puas yog NaCl yog acidic ntsev?
Cov ntsev nws tus kheej tsis yog acidic . Yog tias koj yaj nws, ib qho kev daws teeb meem nruab nrab yuav tsim. Qhov no yog vim li cas hauv dej, NaCl dissociates rau Na+ thiab Cl-. Na + yuav sib txuas nrog hydrogen thiab oxygen los tsim NaOH, lossis sodium hydroxide, lub hauv paus muaj zog, thaum Cl- yuav tsim HCl, lossis hydrochloric acid, muaj zog acid.

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
Qhov twg yog acidic ntau dua ib qho kev daws ntawm pH 2 lossis kev daws ntawm pH 6?
Kev piav qhia: pH yog qhov ntsuas ntawm acidity lossis alkalinity ntawm cov tshuaj. concentration siab dua yog acidity. Yog li ib qho kev daws ntawm pH = 2 yog acidic ntau dua li ntawm pH = 6 los ntawm qhov zoo ntawm 10000
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 )
Puas yog cov lus ntsev acidic lossis yooj yim?
Properties of Table Salt: Rooj ntsev yog cov khoom tsim los ntawm neutralization ntawm cov kua qaub los ntawm lub hauv paus. Yog li nws tsis yog Acid lossis Base. Koj tuaj yeem siv pH Scale los qhia seb nws cov kua qaub lossis lub hauv paus
