Tsis pub
- Yog koj tsuas muaj qaug zog kua qaub . Txiav txim siab qhov concentration ntawm cov kua qaub (xav tias tsis muaj kev sib cais). Saib los yog txiav txim siab Ka.
- Yog koj muaj zog kua qaub THIAB lub conjugate puag . daws rau buffer.
- Yog tias koj tsuas muaj lub conjugate puag . daws rau pH puag siv Kb thiab kev sib npaug hydrolysis.
Raws li, koj ua li cas acid puag titration?
Titration txheej txheem
- Yaug lub burette nrog cov txheej txheem daws teeb meem, lub pipette nrog cov tshuaj tsis paub, thiab lub khob ntim dej nrog dej distilled.
- Muab qhov ntsuas ntsuas qhov ntsuas qhov tseeb rau hauv lub khob Erlenmeyer siv lub pipette, nrog rau ob peb tee ntawm qhov taw qhia.
Ib yam li ntawd, koj ua li cas xam titration? Siv cov titration formula . Yog hais tias tus titrant thiab analyte muaj ib tug 1: 1 mole ratio, lub qauv yog molarity (M) ntawm cov kua qaub x ntim (V) ntawm cov kua qaub = molarity (M) ntawm lub hauv paus x ntim (V) ntawm lub hauv paus. ( Molarity yog cov concentration ntawm cov tshuaj qhia raws li tus naj npawb ntawm moles ntawm solute ib liter ntawm kev daws.)
Dhau li ntawd, yog F yog lub hauv paus muaj zog lossis tsis muaj zog?
Yog li ntawd, kuv- yog qhov ruaj khov tshaj plaws, thiab qhov yooj yim tshaj plaws, thaum F - yog qhov tsawg kawg ruaj khov thiab yooj yim tshaj plaws. Lub hauv paus muaj zog cuam tshuam nrog muaj zog acids zoo li HCl los tsim cov ntsev thiab dej hauv cov tshuaj tiv thaiv neutralization. Lwm yam lub hauv paus muaj zog yog soluble oxides, zoo li Na2O thiab soluble hydroxide ntsev. Lub hauv paus muaj zog yog muaj zog electrolytes.
Dab tsi yog titration siv rau?
A titration yog ib tug txheej txheem uas ib tug paub txog concentration yog siv rau txiav txim siab qhov concentration ntawm ib qho kev daws tsis paub. Feem ntau, titrant (qhov paub daws) yog ntxiv los ntawm ib lub buret mus rau ib qho kev paub ntau ntawm cov tshuaj ntsuam xyuas (cov tshuaj tsis paub meej) kom txog thaum cov tshuaj tiv thaiv tiav.

Cov txheej txheem ntawm kev tsim cov kev daws teeb meem yog dab tsi?
Kev daws yog tsim thaum ib yam khoom hu ua thesolute 'dissolves' rau hauv lwm yam khoom hu ua hnyav.Dissolving yog thaum lub solute tawg los ntawm ib tug loj siv lead ua ntawm molecules mus rau ntau me me los yog ib tug molecules. Lawv ua qhov no los ntawm rub tawm cov ions thiab tom qab ntawd ncig cov ntsev molecules
Dab tsi yog cov kauj ruam los daws cov teeb meem lo lus?
Cov kauj ruam yooj yim rau kev daws cov teeb meem lo lus Nyeem qhov teeb meem. Pib los ntawm kev nyeem qhov teeb meem kom zoo. Txheeb xyuas thiab sau qhov tseeb. Tshawb xyuas seb qhov teeb meem nug yog dab tsi. Tshem tawm cov ntaub ntawv tshaj tawm. Ua tib zoo saib xyuas cov ntsuas ntsuas. Kos ib daim duab. Nrhiav lossis tsim ib qho qauv. Nrog rau kev siv
Dab tsi yog cov kauj ruam los daws qhov tsis sib xws ntawm ob kauj ruam?
Nws yuav siv ob kauj ruam los daws qhov kev sib npaug lossis qhov tsis sib xws uas muaj ntau tshaj ib qho kev ua haujlwm: Simplify siv qhov sib txawv ntawm qhov sib ntxiv lossis rho tawm. Ua kom yooj yim ntxiv los ntawm kev siv qhov sib txawv ntawm qhov sib npaug lossis faib
Cov teeb meem ntau kauj ruam yog dab tsi?
Cov teeb meem lus ntau kauj ruam yog cov teeb meem lej uas muaj ntau tshaj ib qho kev ua haujlwm. Kev ua haujlwm yog ntxiv, rho tawm, sib faib lossis faib. Cov teeb meem lus ntau kauj ruam tuaj yeem muaj kev sib xyaw ua ke ntawm cov haujlwm no hauv nws. Cia peb saib ze dua ntawm qhov teeb meem nrog kev ntxiv thiab rho tawm haujlwm
Cov teeb meem lo lus ntau kauj ruam yog dab tsi?
Qhov teeb meem ntau-kauj ruam yog zoo li ib qho kev sib dhos uas muaj ntau daim. Cov teeb meem lus ntau kauj ruam yog cov teeb meem lej uas muaj ntau tshaj ib qho kev ua haujlwm. Kev ua haujlwm yog ntxiv, rho tawm, sib faib lossis faib. Cov teeb meem lus ntau kauj ruam tuaj yeem muaj kev sib xyaw ua ke ntawm cov haujlwm no hauv nws
