Titration » Volumetric iav calibration . Muaj peev xwm los ntsuas qhov ntim ntawm cov tshuaj yog qhov tseem ceeb rau qhov tseeb ntawm kev tshuaj xyuas tshuaj. Qhov hnyav tuaj yeem ua tiav nrog qhov tseeb zoo, thiab paub txog qhov ntom ntom ntawm cov dej peb tuaj yeem suav cov ntim ntawm cov dej loj. Yog li peb tuaj yeem txiav txim siab lub peev xwm ntawm qhov tseeb iav.
Kuj nug, lub hom phiaj ntawm calibration ntawm volumetric glassware yog dab tsi?
Volumetric iav yog ib chav kawm ntawm iav hlab ntsha uas yog calibrated kom muaj lossis xa cov ntim ntawm cov khoom. Txhawm rau kom tsis txhob qhia qhov yuam kev hauv kev ntsuas, txhua yam ntawm cov cuab yeej no yuav tsum ua kom raug calibrated.
Ib sab saum toj no, Burets calibrated li cas? Kov lub ntsis ntawm lub buret mus rau sab ntawm lub beaker kom tshem tawm qhov poob dai ntawm lub taub. Tom qab li ib feeb, kom tso dej tawm, ua qhov pib nyeem ntawm meniscus, kwv yees qhov ntim mus rau qhov ze tshaj 0.01 mL. Sau qhov pib nyeem ntawv. Tso cai rau buret sawv ntsug li 5 feeb thiab rov xyuas qhov kev nyeem ntawv.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog calibration ntawm iav?
iav feem ntau yog calibrated siv cov kua uas paub, tshwj xeeb ceev, thiab kev ntsuas ntsuas. Cov txheej txheem yog los txiav txim qhov loj ntawm cov kua iav yuav tuav, thiab faib qhov loj ntawm cov kua los ntawm qhov ntom ntawm cov kua, tau txais qhov sib thooj ntawm cov kua.
Vim li cas lub raj mis volumetric yog qhov tseeb dua?
Raws li Richard Routhier tau hais, volumetric khob yog tseeb dua vim lawv raug calibrated ntawm ib lub ntim tshwj xeeb[1]. Qhov ntawd txhais tau hais tias koj yuav tau txais tus qauv ntim, xyuas seb qhov meniscus nyob qhov twg thiab tom qab ntawd tsim lub cim rau lub ntim.

Vim li cas peb yuav tsum tau mash txiv hmab txiv ntoo hauv kev cais DNA?
Cov txiv hmab txiv ntoo no tau raug xaiv vim lawv yogtriploid (bananas) thiab octoploid (strawberries). Qhov no txhais tau hais tias lawv muaj ntau DNA hauv lawv lub hlwb, uas txhais tau hais tias muaj ntau ntau rau peb rho tawm. Lub hom phiaj ntawm themashing yog los rhuav tshem cov phab ntsa ntawm tes
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
Vim li cas nws thiaj li yuav tsum tau ua kom cov txiv pos nphuab hauv DNA rho tawm?
Txheej txheem. Lub hom phiaj ntawm kev sib tsoo cov txiv pos nphuab yog txhawm rau rhuav tshem cov phab ntsa ntawm tes nrog rau cov cellular thiab cov ntaub so ntswg. Lub extraction tsis pab tso tawm DNA los ntawm ib puag ncig cell Cheebtsam ntawm crushed strawberry. Cov lim tau siv los tshem tawm cov khoom loj ntawm cov tshuaj xws li cov noob
Vim li cas nuclear fais fab nroj tsuag yuav tsum tau nyob ze dej?
Thaum muaj xwm txheej, cov chaw tsim hluav taws xob nuclear xav tau dej los pab tshem tawm cov cua sov uas tsim los ntawm cov tub ntxhais reactor. Coal burning fais fab nroj tsuag nyob ze dej vim hais tias cov dej yog siv los tsim lub zog. Cov chav ntws mus rau hauv lub turbine uas tig, thiab tsim hluav taws xob
Vim li cas cov cell membrane yuav tsum tau thauj cov proteins?
Kev piav qhia: Lawv pab cov molecules thoob plaws hauv daim nyias nyias ntawm kev thauj mus los, ib txoj kev hu ua kom yooj yim diffusion. Cov proteins no yog lub luag haujlwm rau nqa ions thiab lwm cov molecules me rau hauv lub cell
