Lub hauv paus yog ib qho yam khoom uas reacts nrog ib tug acid rau daim ntawv a ntsev thiab dej xwb.
Nyob rau hauv tas li ntawd, dab tsi reacts nrog ib tug acid los tsim ib tug soluble ntsev?
2 Ib qho insoluble hlau carbonate reacts nrog ib tug dilute acid los ua ib tug soluble ntsev . Magnesium carbonate, cov khoom dawb, thiab dilute sulfuric acid react rau tsim magnesium sulfate.
Kuj Paub, qhov tshuaj tiv thaiv hu ua dab tsi thaum cov kua qaub reacts nrog alkali? Ib kua qaub - alkali neutralization yog qhov tshuaj tiv thaiv nruab nrab ntawm hydrogen ions thiab hydroxide ions, tsim dej.
Tsis tas li ntawd, yuav ua li cas soluble ntsev ua los ntawm acids thiab insoluble tshuaj?
Rau ua a soluble ntsev los ntawm ib kua qaub thiab ib insoluble reactant: Ntxiv hmoov insoluble reactant rau kua qaub Nyob rau hauv ib lub lauj kaub, ib tug spatula ntawm ib lub sij hawm, stirring rau mix. Ntxiv cov hmoov nplej ntxiv kom txog thaum nws dhau lawm (qee cov hmoov uas tsis muaj tshuaj tiv thaiv tau tso tseg). Lub filtrate tam sim no tsuas muaj cov ntsev thiab dej.
Puas yog tag nrho cov hlau ua rau cov kua qaub los tsim cov ntsev?
Ntau, tab sis tsis yog tag nrho , hlau reacts nrog acids . Hydrogen gas daim ntawv raws li cov hlau react nrog rau acid los ua ntsev.

Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Koj puas tuaj yeem ntxuav tooj liab nrog kua qaub?
Hydrochloric lossis Muriatic Acid Copper hloov ntsuab thaum nws yog oxidized. Thaum cov khoom ntsuab tsim, nws tuaj yeem raug ntxuav kom huv si siv cov tshuaj uas muaj hydrochloric lossis muriatic acid. Cov no yog cov tshuaj zoo tshaj plaws los ntxuav cov tooj liab
Dab tsi yog qhov txawv ntawm kev cuam tshuam kev cuam tshuam thiab kev cuam tshuam cuam tshuam?
Paub qhov txawv ntawm kev cuam tshuam kev tsim kho thiab kev cuam tshuam puas tsuaj. Kev tsim kev cuam tshuam tshwm sim thaum lub crests ntawm ob nthwv dej ntxiv ua ke. Kev cuam tshuam kev puas tsuaj tshwm sim thaum lub crest ntawm ib yoj raug txo los ntawm lub trough ntawm lwm tus
Cov ntsev puas cuam tshuam nrog cov hauv paus?
Yog lawm, cov tshuaj tiv thaiv zoo li no muaj ntau hauv cov tshuaj inorganic. (1) Lub hauv paus muaj zog tuaj yeem cuam tshuam nrog ntsev ntawm lub hauv paus tsis muaj zog thiab tshem tawm. Lwm cov alkalis (cov hauv paus muaj zog) zoo li NaOH thiab KOH kuj tau yooj yim tso ammonia ntawm kev ua kom sov nrog ammonium ntsev
Cov tshuaj tiv thaiv hu ua dab tsi thaum cov kua qaub reacts nrog lub hauv paus?
Cov tshuaj tiv thaiv ntawm cov kua qaub nrog lub hauv paus yog hu ua cov tshuaj tiv thaiv neutralization. Cov khoom ntawm cov tshuaj tiv thaiv no yog ntsev thiab dej. Piv txwv li, cov tshuaj tiv thaiv ntawm hydrochloric acid, HCl, nrog sodium hydroxide, NaOH, cov kev daws teeb meem tsim cov tshuaj sodium chloride, NaCl, thiab qee cov dej molecules ntxiv
