Chlorine tuaj yeem pom muaj ntau nyob rau hauv ob lub ntiaj teb crust thiab hauv dej hiav txwv. Hauv dej hiav txwv, tshuaj chlorine yog pom raws li ib feem ntawm cov compound sodium chloride (NaCl), los yog lub rooj ntsev. Nyob rau hauv lub ntiaj teb crust, feem ntau cov minerals uas muaj tshuaj chlorine suav nrog halite (NaCl), carnallite, thiab sylvite (KCl).
Yog li, chlorine puas yog ib qho khoom siv ntuj?
Chlorine yog ib qho roj reactive heev. Nws yog ib qho tshwm sim tshwm sim. Cov neeg siv loj tshaj plaws ntawm tshuaj chlorine yog cov tuam txhab uas ua ethylene dichloride thiab lwm yam chlorinated Cov kuab tshuaj, polyvinyl chloride (PVC) resins, chlorofluorocarbons, thiab propylene oxide.
Qhov thib ob, chlorine pom nyob rau hauv dab tsi? 1774 ib
Kuj Paub, chlorine nyob qhov twg hauv tib neeg lub cev?
Chlorine (0.15%) feem ntau pom nyob rau hauv lub cev raws li ib tug tsis zoo ion, hu ua tshuaj chloride . Cov electrolyte no tseem ceeb heev rau kev tswj kom muaj qhov sib npaug ntawm cov kua dej. Magnesium (0.05%) plays lub luag haujlwm tseem ceeb hauv cov qauv ntawm cov pob txha thiab cov leeg. Nws tseem yog qhov tsim nyog hauv ntau dua 300 qhov tseem ceeb metabolic cov tshuaj tiv thaiv.
Puas yog txiv neej chlorine tsim?
Raws li tshuaj chlorine yog ib tug natural keeb, nws muaj nyob rau hauv lub ntiaj teb nws tus kheej. Nws pom nyob rau 7/10 ntawm lub ntiaj teb vim nws pom tseeb hauv ntsev. Lub npe rau kev sib xyaw ua ke no yog sodium chloride (NaCl). Txawm tias Chlorine yog ib tug natural element, nyob rau hauv ntau txiv neej ua reservoir, cov Chlorine yog ntxiv los tiv thaiv dej.

Yam tshuaj twg tsis tuaj yeem decomposed los ntawm cov tshuaj txhais tau tias?
Cov ntsiab lus yog cov khoom ntshiab uas tsis tuaj yeem decomposed los ntawm cov tshuaj zoo tib yam xws li cua sov, electrolysis, los yog cov tshuaj tiv thaiv. Kub, nyiaj, thiab oxygen yog piv txwv ntawm cov khoom. Compounds yog cov khoom ntshiab tsim los ntawm kev sib xyaw ua ke ntawm cov ntsiab lus; lawv tuaj yeem decomposed byordinary tshuaj txhais tau tias
Cov pab pawg twg ntawm cov ntawv teev sijhawm twg yog cov tshuaj chlorine?
Chlorine belongs rau pab pawg neeg ntawm halogens - ntsev tsim - ua ke nrog fluorine (F), bromine (Br), iodine (I) thiab astatine (At). Lawv tag nrho nyob rau hauv kab thib ob los ntawm sab xis ntawm lub rooj sib tham hauv Pawg 17. Lawv cov teeb tsa hluav taws xob zoo sib xws, muaj xya lub tshuab hluav taws xob hauv lawv lub plhaub sab nraud
Qhov kev sib npaug twg yog qhov tsim nyog los suav cov cua sov uas tsim los ntawm HCl NaOH cov tshuaj tiv thaiv?
Xam cov naj npawb ntawm moles ntawm lub hauv paus koj ntxiv los txiav txim siab molar tshav kub ntawm qhov nruab nrab, qhia siv qhov sib npaug Δ H = Q ÷ n, qhov twg 'n' yog tus naj npawb ntawm moles. Piv txwv li, xav tias koj ntxiv 25 mL ntawm 1.0 M NaOH rau koj HCl los ua kom muaj cua sov ntawm nruab nrab ntawm 447.78 Joules
Dab tsi yog chlorine dawb thiab tag nrho cov tshuaj chlorine?
Cov tshuaj dawb chlorine yog hais txog ob qho tib si hypochlorous acid (HOCl) thiab hypochlorite (OCl-) ion lossis tshuaj dawb, thiab feem ntau ntxiv rau cov dej rau kev tua kab mob. Tag nrho cov tshuaj chlorine yog qhov suav ntawm cov tshuaj dawb dawb thiab cov tshuaj chlorine ua ke. Qib ntawm tag nrho cov tshuaj chlorine yuav tsum ib txwm siab dua lossis sib npaug ntawm cov tshuaj chlorine dawb
Qhov twg tuaj yeem siv los qhia txog qhov concentration ntawm cov tshuaj?
Molarity (M) qhia cov naj npawb ntawm moles ntawm cov kuab tshuaj ib liter ntawm kev daws (moles / Liter) thiab yog ib qho ntawm feem ntau units siv los ntsuas qhov concentration ntawm cov tshuaj. Molarity yuav siv tau los xam qhov ntim ntawm cov kuab tshuaj los yog tus nqi ntawm cov kuab tshuaj
