Ua ntej, koj yuav ncuav ib co ntsev rau hauv lub lauj kaub distil. Tom qab no, koj yuav ntxiv nyob rau hauv ib co concentrated sulfuric acid mus rau ntsev. Tom ntej no, koj yuav cia cov no cuam tshuam nrog ib leeg. Koj yuav pib pom gasses npuas thiab cov roj hydrogen chloride tshaj tawm los ntawm lub raj sab saum toj.
Tsis tas li ntawd, yuav ua li cas thaum hydrochloric acid reacts nrog sulfuric acid?
Feem ntau, thaum peb ntxiv dilute hydrochloric acid mus rau ib tug muaj zog (los yog concentrated) tov ntawm sulfuric acid , lub cev qhuav dej tshuaj tiv thaiv siv qhov chaw. Hauv no tshuaj tiv thaiv , cov sulfuric acid strips cov hydrochloric acid ntawm nws cov dej, zoo converting nws mus hydrochloric acid gas.
Tom qab ntawd, lo lus nug yog, yuav ua li cas koj ua hydrochloric acid los ntawm hydrogen chloride? Cl2(g) + H2(g) → 2 HCl (g) Raws li cov tshuaj tiv thaiv yog exothermic, lub installation yog hu ua ib HCl cub lub HCl lub tshuab hluav taws xob. Qhov tshwm sim hydrogen chloride Gas yog absorbed nyob rau hauv dej deionized, uas ua rau chemically ntshiab hydrochloric acid.
Tsis tas li ntawd, lawv ua li cas ua hydrochloric acid?
Ntau lawm. Hydrochloric acid yog npaj los ntawm dissolving hydrogen chloride hauv dej.
Kuv tuaj yeem tau txais hydrochloric acid nyob qhov twg?
Hydrochloric acid muaj nyob rau ntawm zoo nkauj ntau lub khw muag khoom kho vajtse lossis lub khw muag khoom pas dej ua ke. Nws yog muag nyob rau hauv ib nrab lub zog (rau kev nyab xeeb yog vim li cas) kev daws teeb meem hauv dej nrog lub npe lag luam muriatic kua qaub ”.
Pom zoo:
Dab tsi yog cov khoom ntawm ionization ntawm hydrochloric acid hauv dej?
Hydrogen chloride (HCl) ionizes tag nrho rau hauv hydrogen ions thiab chloride ions hauv dej
Dab tsi yog lub npe ntsev tsim los ntawm neutralization ntawm hydrochloric acid thiab sodium hydroxide?
Kev piav qhia: Cov tshuaj tiv thaiv ntawm sodium hydroxide (NaOH) thiab hydrochloric acid (HCl) yog cov tshuaj tiv thaiv nruab nrab uas ua rau muaj ntsev, sodium chloride (NaCl), thiab dej (H2O). Nws yog ib qho tshuaj tiv thaiv exothermic
Yuav ua li cas tshwm sim thaum sodium reacts nrog hydrochloric acid?
Sodium hlau reacts nrog hydrochloric acid los ua ntsev thiab hydrogen gas. Qhov no txhais tau hais tias koj cov reactants yuav yog sodium hlau thiab hydrochloric acid, vim cov no yog cov khoom uas tau hloov mus rau hauv cov ntsev thiab hydrogen gas
Puas muaj qhov sib txawv ntawm muriatic acid thiab hydrochloric acid?
Tsuas yog qhov sib txawv ntawm hydrochloricacid thiab muriatic acid yog purity-muriaticacid yog diluted rau qhov chaw ntawm 14.5 thiab 29 feem pua, thiab feem ntau muaj impurities xws li hlau. Cov impurities no yog dab tsi ua rau muriatic acid ntau daj-toned dua li purehydrochloric acid
Yuav ua li cas tshwm sim thaum dilute sulfuric acid yog nchuav rau ntawm zinc phaj?
Thaum dilute Sulfuric acid yog nchuav rau ntawm ib lub zincplate, Zinc Sulphate yog tsim nrog Hydrogen gas.Peb tuaj yeem kuaj cov roj hydrogen los ntawm kev noj cov khoom siv hluav taws xob ze ze, thiab cov roj yuav ignite nrog lub suab nrov
