Kev daws ntawm NaCl hauv dej tsis muaj acidic orbasic lwm yam ntsev uas tsim cov kev daws teeb meem nruab nrab suav nrog potassium nitrate (KNO) 3) thiab lithium bromide ( LiBr ). Tablebelow piav qhia yuav txiav txim siab li cas acidity los yog lub hauv paus ntawm kev daws ntsev.

Ib yam li ntawd, yog Na2S acidic lossis yooj yim?

Na2S yog ntsev ntawm ib qho tsis muaj zog acid (H2S) thiab muaj zog puag (NaOH). Kev daws cov dej ntawm cov ntsev no yog qhov txawv txav yooj yim vim muaj cov OH-ions ntxiv uas yog tsim los ntawm hydrolysis ntawm anion. Yog li, Na2S kuj yog ib yooj yim ntsev zoo li Na2CO3, CaCO3, CH3COONaetc.

kc2h3o2 yog kua qaub lossis hauv paus? Kev daws dej ntawm KC2H3O2 yuav yooj yim. TheK+ yog cation ntawm qhov muaj zog puag (KOH), yog li nws yog aneutral ion thiab tsis cuam tshuam rau pH ntawm cov tshuaj. TheC2H3O2- yog los ntawm qhov tsis muaj zog kua qaub (HC2H3O2), yog li nws yog lub hauv paus.

Hauv qhov no, KCl acidic lossis yooj yim?

Cov ions los ntawm KCl muab los ntawm lub zog kua qaub (HCl) thiab muaj zog puag (KOJ). Yog li ntawd, tsis muaj ion yuav cuam tshuam rau acidity ntawm kev daws, yog li KCl yog ntsev nruab nrab. Txawm hais tias K + ionderives los ntawm ib qho muaj zog puag (KOJ), NO 2 ion muab los ntawm qhov tsis muaj zog kua qaub (HNO2).

Puas yog NH4Br acidic lossis yooj yim?

Piv txwv li, NH4Br yog ntsev ntawm ib tug qaug zog puag (NH3) thiab muaj zog kua qaub (HBr), yog li ntsev kua qaub . Ib yam li ntawd, NaF yog yooj yim (nws yog ntsev ntawm astrong puag , NaOH, thiab qaug zog kua qaub , HF). NaCl tsis tsim nyog.
