b) NaH2PO4 thiab Na2HPO4 yog an acid/base conjugate khub Lawv yuav ua rau qhov tsis zoo. c) H2CO3 thiab NaHCO3 kuj yog cov kua qaub / puag conjugate khub thiab lawv yuav ua rau qhov tsis zoo. Cov pa roj carbonic acid / bicarbonate tsis tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev tswj hwm pH ntawm koj cov ntshav ntawm tus nqi tas li.
Nahpo4 puas yog lub hauv paus?
Na2HPO4 yog ntsev. …
Nahpo4 ntsev yog dab tsi?
NaH2PO4 yog an acid ntsev vim nws muaj ob lub hloov pauv hydrogen atoms (ob OH daim ntawv cog lus) raws li tau piav qhia meej los ntawm nws cov qauv.
Puas yog na2 hpo4 acidic ntsev?
Cov lus teb ib ntus:
NaH2PO2 yog tsim los ntawm kev ua kom tsis muaj zog ntawm cov kua qaub H3PO2 thiab muaj zog hauv paus NaOH.… Yog li, NaH2PO2 tsis yog ntsev ntsev Yog li, kev xaiv (A) yog qhov tseeb. Cov ntsev NaH2PO3 yog tsim los ntawm neutralization ntawm qaug zog acid H3PO3 thiab muaj zog puag NaOH.
Is Na2HPO4 Basic ntsev?
Na2pho4 yog acidic ntsev. Kev piav qhia: yog hu ua acidic ntsev vim nws muaj ib qho acidic hydrogen thiab li no tuaj yeem ua rau lub hauv paus. Txawm li cas los xij nws yog cov tshuaj aqueous yog qhov yooj yim vim nws yog ntsev ntawm lub hauv paus muaj zog thiab tsis muaj zog acid.

Yuav ua li cas cov tshuaj ntxuav tais diav? tshuaj ntxuav tais diav (tseem hu ua cov tshuaj ntxuav tais diav lossis kua ntxuav tais diav) yog ib daim ntawv tshwj xeeb ntawm xab npum uas muaj sib tov ntawm surfactants(cov tshuaj tsim los ua kom tawg qhov nro ntawm cov khib nyiab) uas yog tshwj xeeb tshaj yog ua
Puas yog cov kua qaub-ceev mycobacteria gram-positive lossis gram-negative?
Acid-fast bacteria yog gram-positive , tab sis ntxiv rau peptidoglycan, cov txheej membrane los yog lub hnab ntawv ntawm cov phab ntsa ntawm cov kua qaub-ceev cell ntawm cov glycolipids ntau, tshwj xeeb tshaj yog mycolic acids mycolic acids Mycolic acids yog ntev fatty acids pom nyob rau hauv cov phab ntsa ntawm tes ntawm Mycolatataxon, ib pawg ntawm cov kab mob uas suav nrog Mycobacterium tuberculosis, tus neeg sawv cev ntawm tus kab mob tuberculosis.
Magnolia cov hauv paus hniav puas ua puas lub hauv paus?
Txawm li cas los xij, cov cag ntoo magnolia tsis suav tias yog qhov cuam tshuam thiab muaj peev xwm ua kom puas tsuaj raws li qee cov hauv paus hniav. Tab sis lawv kev sib kis loj tuaj yeem cuam tshuam rau lub hauv paus tsis muaj zog Cov ntoo magnolia loj tuaj yeem ua rau muaj teeb meem hauv lub hauv paus yog tias lawv thaiv phab ntsa hauv tsev los ntawm tshav ntuj thiab tsim cov dej ntub dej .
Dab tsi ua rau cov kua qaub ua kua qaub?
Ib tug kua qaub yog ib yam khoom uas pub hydrogen ions Vim li no, thaum cov kua qaub yaj hauv dej, qhov sib npaug ntawm hydrogen ions thiab hydroxide ions hydroxide ions Hydroxide yog diatomic anion nrog tshuaj formula OH - Nws muaj cov pa oxygen thiab hydrogen atom tuav ua ke los ntawm ib qho kev sib cog lus, thiab nqa cov hluav taws xob tsis zoo.
