Sau lub tog raj kheej txog ib nrab ntawm cov tshuaj sodium chloride. Ntxiv ob peb droppers puv ntawm nyiaj nitrate tov rau lub tog raj kheej. Tam sim ntawd ib tug dawb nag xob nag cua daim ntawv. Nyiaj nitrate yog ib tug muaj zog oxidizer, tab sis cov tshuaj yog haum dilute.
Raws li, ua li cas koj precipitate silver kua?
A. Txoj kev yooj yim tshaj plaws los rho tawm nyiaj - quantitatively - los ntawm nyiaj nitrate daws , tsuas yog ntxiv sodium chloride (lub rooj ntsev) daws . Nyiaj chloride yuav nag xob nag cua thiab yog yooj yim heev decanted thiab/los yog lim.
Ib sab saum toj no, vim li cas AgCl yog nag lossis daus? Silver chloride nag xob nag cua tsis huv AgCl . Lawv yog cov clotted loj me me AgCl cov khoom sib txuas ua ke los ntawm electrolyte ions. Piv txwv li, ib qho nitrate ion daig rau ib qho tuaj yeem nyiam Ag+ ions los yog Cu2+ ions daig rau lwm cov khoom.
Tsuas yog li ntawd, koj ua li cas precipitate silver chloride?
Silver chloride yog yooj yim synthesized los ntawm combining aqueous daws ntawm nyiaj nitrate thiab sodium tshuaj chloride . Nws kuj tuaj yeem tsim los ntawm kev ua pa nyiaj nitrate nrog cobalt (II) tshuaj chloride . Qhov no nag lossis daus yog general rau nyiaj nitrate cov tshuaj tiv thaiv nrog soluble tshuaj chloride ntsev thiab tsis yog tshwj xeeb rau cobalt.
Cov xim ntawm AgCl precipitate yog dab tsi?
dawb

Koj yuav tsum teeb tsa koj lub thawv TLC li cas?
Kev teeb tsa thiab khiav TLC Ib qho me me ntawm elutant yog nchuav rau hauv lub thawv (mus rau qhov tob txog 1/2 txog 2/3 ntawm hauv qab ntawm TLC daim ntawv-rau-pib kab nrug), thiab ib daim duab plaub ntawm cov ntawv lim tau muab tso rau hauv qab ntawm daim ntawv TLC. hais tias nws kov tus elutant thiab nyob rau ntawm lub hub phab ntsa, feem ntau saum lub pas dej elutant
Yuav ua li cas koj txiav txim siab npaum li cas ntawm cov kua qaub uas yuav tsum tau neutralize lub hauv paus?
Kev daws qhov teeb meem Acid-Base Neutralization Kauj Ruam 1: Muab xam cov moles ntawm OH-. Molarity = moles / ntim. moles = Molarity x Volume. moles OH- = 0.02 M/100 milliliters. Kauj ruam 2: Xam qhov ntim ntawm HCl xav tau. Molarity = moles / ntim. Volume = moles/molarity. Volume = moles H+/0.075 Molarity
Yuav ua li cas yog tias koj tau txais tooj liab sulfate hauv koj lub qhov muag?
Dab tsi yog qee yam cim thiab cov tsos mob los ntawm kev raug luv luv rau tooj liab sulfate? tooj liab sulfate tuaj yeem ua rau mob qhov muag hnyav. Kev noj ntau ntawm tooj liab sulfate tuaj yeem ua rau xeev siab, ntuav, thiab kev puas tsuaj rau lub cev nqaij daim tawv, cov ntshav, lub siab, thiab lub raum. Nrog rau qhov tshwm sim loj heev, kev poob siab thiab kev tuag tuaj yeem tshwm sim
Yuav ua li cas yog lub hauv paus xeev electron configuration ntawm ib tug silver atom?
Hauv av xeev electron configuration ntawm hauv av xeev gaseous nruab nrab nyiaj yog [Kr]. 4d10 ua. 5s1 thiab lub sij hawm cim yog 2S1/2
Thaum twg koj yuav tsum siv correlation thiab thaum twg koj yuav tsum siv yooj yim linear regression?
Regression feem ntau yog siv los tsim cov qauv / qhov sib npaug los kwv yees cov lus teb tseem ceeb, Y, los ntawm cov txheej txheem kwv yees (X) sib txawv. Kev sib raug zoo feem ntau yog siv los ua kom sai thiab ua kom luv luv cov kev taw qhia thiab lub zog ntawm kev sib raug zoo ntawm ib pawg ntawm 2 lossis ntau tus lej sib txawv
