Qhov sib txawv tseem ceeb ntawm cov ntsev ib txwm thiab cov ntsev ntsev yog cov ntsev ib txwm tsim los ntawm kev sib xyaw ntawm cov kua qaub thiab lub hauv paus muaj zog, whereas kua qaub ntsev tsim los ntawm kev sib xyaw ntawm cov kua qaub tsis muaj zog thiab lub hauv paus muaj zog.
Ib txwm ntsev yog cov ntxhia hauv cov ntxhia uas muaj feem ntau ntawm sodium chloride. Acid ntsev yog cov ntsev sib xyaw ua ke los ntawm kev hloov tsis tiav ntawm hydrogen atom ntawm cov kua qaub.
Nom ntsev yog dab tsi?
Ib txwm ntsev yog cov ntxhia hauv cov ntxhia uas muaj feem ntau ntawm sodium chloride. Nws belongs rau cov chav kawm loj ntawm cov ntsev tebchaw uas yog ib txwm tshwm sim crystalline tshuaj. Daim ntawv tshwm sim ntawm ib txwm ntsev yog pob zeb ntsev los yog halite. Ntxiv mus, peb tuaj yeem pom ntsev hauv dej hiav txwv hauv ntau qhov ntau. Cov tshuaj no ua rau lub qab ntsev ntawm dej hiav txwv.
Feem ntau, ntsev yog ib qho tseem ceeb ntawm lub neej thiab yog ib qho ntawm tib neeg saj. Ntsev yog qhov qub tshaj plaws saj thiab siv tau los ua zaub mov seasoning. S alting kuj tseem ceeb hauv kev khaws zaub mov.
Daim duab 01: Rooj ntsev thiab chav ua mov ntsev
Peb tuaj yeem tau ntsev los ntawm cov dej ntsev thiab dhau los ntawm cov dej hiav txwv evaporation lossis cov dej caij nplooj ntoos hlav uas muaj cov ntxhia hauv cov pas dej ntiav. Cov khoom lag luam loj uas peb tuaj yeem tsim siv cov ntsev ib txwm muaj xws li caustic soda thiab chlorine. Tsis tas li ntawd, muaj qee qhov kev siv ntau dua ntawm cov ntsev ib txwm, nrog rau cov txheej txheem dej txias, de-icing txoj kev loj, kev siv ua liaj ua teb, thiab lwm yam.
Feem ntau, thaum peb xa mus rau cov ntsev ib txwm, peb tab tom tham txog cov ntsev ntsev, uas yog daim ntawv uas siv tau los ntawm cov ntsev ib txwm. Nws yog ib qho tshuaj lom neeg hauv tsev ntau tshaj plaws. Nws muaj txog 97% sodium chloride nyob rau hauv daim ntawv ntawm ionic crystals.
Acid S alt yog dab tsi?
Acid ntsev yog cov ntsev sib xyaw ua ke los ntawm kev hloov tsis tiav ntawm hydrogen atom ntawm cov kua qaub. Cov ntsev tebchaw no tuaj yeem tsim cov kua qaub tom qab yaj hauv cov kuab tshuaj xws li dej. Qhov kev daws teeb meem acidic no tshwm sim vim yog ib feem ntawm qhov nruab nrab ntawm diprotic lossis polyprotic acids. Hauv cov txheej txheem neutralization no, ib nrab-neutralization tshwm sim. Qhov no yog vim hais tias cov seem hloov tau hydrogen atoms nyob rau hauv cov kua qaub uas tsis muaj zog uas tab tom muaj ib nrab dissociation tsis hnov mob nrog hydroxide ions los tsim cov dej molecules. Ntxiv mus, peb tuaj yeem txhais cov kua qaub ntsev ua ib qho ionic compound uas muaj cov anion uas los ntawm cov niam txiv tsis muaj zog acid thiab cov cation uas los ntawm cov niam txiv muaj zog.
Daim duab 02: Monosodium Phosphate
Qee cov piv txwv ntawm cov ntsev ntsev muaj xws li sodium bisulfate, monosodium phosphate thiab disodium phosphate. Cov ntsev sib xyaw no feem ntau muaj txiaj ntsig zoo hauv cov khoom noj uas yog ib feem ntawm cov tshuaj tua kab mob. Peb hu cov tebchaw leavening acids. E.g. monocalcium phosphate. Ntxiv mus, peb tuaj yeem sib tov kua qaub ntsev nrog alkali ntsev los tsim cov hmoov ci. Tsis tas li ntawd, peb tuaj yeem siv monosodium phosphate hauv tsiaj pub, tshuaj txhuam hniav, thiab evaporated mis nyuj.
Dab tsi yog qhov txawv ntawm cov ntsev ib txwm thiab acid ntsev?
Ib qho ntsev yog ib qho ionic compound. Muaj ntau hom ntsev, xws li kua qaub ntsev thiab alkali slats. Qhov sib txawv tseem ceeb ntawm cov ntsev ib txwm thiab cov ntsev ntsev yog cov ntsev ib txwm tsim los ntawm kev sib xyaw ntawm cov kua qaub thiab lub hauv paus muaj zog, thaum cov kua qaub ntsev tsim los ntawm kev sib xyaw ntawm cov kua qaub tsis muaj zog thiab lub hauv paus muaj zog. Txawm hais tias ib txwm ntsev yog nruab nrab, acid ntsev yog acidic.
Cov hauv qab no infographic teev qhov sib txawv ntawm cov ntsev ib txwm thiab kua qaub ntsev hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Ib txwm ntsev vs Acid ntsev
Ib txwm ntsev yog cov ntxhia hauv cov ntxhia uas muaj feem ntau ntawm sodium chloride. Acid ntsev yog cov ntsev sib xyaw ua ke los ntawm kev hloov tsis tiav ntawm hydrogen atoms ntawm cov kua qaub. Qhov sib txawv tseem ceeb ntawm cov ntsev ib txwm thiab cov kua qaub yog cov ntsev ib txwm tsim los ntawm kev sib xyaw ntawm cov kua qaub thiab lub hauv paus muaj zog whereas acid ntsev tsim los ntawm kev sib xyaw ntawm cov kua qaub tsis muaj zog thiab lub hauv paus muaj zog.
