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.

Puas yooj yim lossis sib xyaw paj zoo dua?
Cov paj laum yooj yim yog nyob ntawm tus nqi tseem ceeb ntawm cov nyiaj qiv lossis tso nyiaj, thaum cov paj laum sib xyaw ua raws li tus nqi tseem ceeb thiab cov paj laum uas sau rau hauv txhua lub sijhawm. Txij li cov paj laum yooj yim tsuas yog xam rau ntawm tus nqi ntawm cov nyiaj qiv lossis tso nyiaj, nws yooj yim dua los txiav txim siab dua li cov paj laum
Cov qauv puas ua raws li lub tswv yim lossis lub tswv yim ua raws li qauv?
Cov qauv txhawb nqa lub tswv yim. Yog tias ib lub koom haum hloov nws lub tswv yim, nws yuav tsum hloov nws cov qauv los txhawb lub tswv yim tshiab. Thaum nws tsis ua, cov qauv ua haujlwm zoo li lub bungee qaum thiab rub lub koom haum rov qab mus rau nws cov tswv yim qub. Lub tswv yim ua raws li cov qauv
Puas yog peat moss alkaline lossis acidic?
Raws li tau sau tseg saum toj no, peat Moss muaj acidic pH, feem ntau nyob rau hauv thaj tsam ntawm 4.4 (pH ntawm 7 yog nruab nrab; siab dua pH tooj qhia alkaline av). Peat moss kuj yog plua plav heev; Ntxiv nrog rau kev ntxhov siab, peat moss tuaj yeem ua rau koj lub ntsws
Cov tswv yim tswj kev yooj yim yog dab tsi?
Thib ob, nws hais txog plaub yam kev tswj hwm: Kev Npaj, kev npaj, ua, thiab tswj. Kev npaj yog xav txog kev ua ua ntej. Kev koom tes yog kev sib koom tes ntawm tib neeg thiab cov khoom siv ntawm ib lub koom haum. Kev ua haujlwm yog kev txhawb siab thiab kev coj ntawm cov neeg ua haujlwm
Vim li cas nws tseem ceeb kom ua kom yooj yim cov lus qhia ua ntej sib faib lossis faib?
Simplifying rational expressions yuav ua rau cov kev xam ntxiv yooj yim dua vim hais tias cov variables ua hauj lwm nrog feem ntau yuav me me. Txhawm rau txiav txim siab tias qhov kev qhia muaj txiaj ntsig yog nyob rau hauv daim ntawv yooj yim peb yuav tsum xyuas kom meej tias tus lej thiab tus lej tsis muaj qhov sib txawv
