Hauv cov kua qaub-tsis muaj zog hauv paus titrations, pH ntawm qhov sib npaug tsis yog 7 tab sis hauv qab nws . Qhov no yog vim kev tsim cov kua qaub conjugate thaum lub sij hawm titration; Nws yuav hnov mob nrog dej los tsim hydronium (H 3 O +) ions.
Dab tsi tuaj yeem ua rau pH ntawm titration txawv ntawm 7.0 ntawm qhov sib npaug?
qhov concentration ntawm cov txheej txheem daws teeb meem. Qhov sib npaug ntawm qhov titrations yuav txawv ntawm 7 vim yog ntsev hydrolysis.
Puas yog qhov sib npaug thaum nws nruab nrab?
1) Qhov sib npaug ntawm cov tshuaj tiv thaiv acid-puag (lub taw tes ntawm cov kua qaub thiab cov hauv paus tsuas yog txaus los ua kom tiav neutralization). 2) Cov pH ntawm cov tshuaj ntawm qhov sib npaug ntawm qhov sib npaug yog nyob ntawm lub zog ntawm cov kua qaub thiab lub zog ntawm lub hauv paus siv hauv titration.
Qhov twg hauv qab no muaj tseeb ntawm qhov sib npaug ntawm pH ib txwm yog 7?
Thiab thaum peb tab tom tham txog tus nqi, peb tab tom tham txog moles thaum lub sij hawm acid raws li dej. Qhov no muaj tseeb ntawm qhov sib npaug. Koj muaj cov moles sib npaug ntawm cov kua qaub thiab lub hauv paus ua ke ntawm qhov sib npaug taw tes. Tus pH ib txwm yog xya.
Koj paub li cas thaum koj mus txog qhov sib npaug?
Nyob rau hauv ob qho tib si, qhov sib npaug taw tes yog mus txog thaum moles ntawm cov kua qaub thiab lub hauv paus sib npaug thiab pH yog 7. Qhov no kuj sib xws rau cov ximhloov ntawm qhov ntsuas. … Ib qho titration nkhaus qhia cov pH hloov uas tshwm sim thaum lub sij hawm titration ntawm cov kua qaub nrog lub hauv paus. Ntawm sab laug, lub hauv paus tau ntxiv rau acid.

Thaum tus lej sib npaug y yog tus lej sib npaug?
Thaum muab tus lej Y yog tus lej sib npaug X=xn – 1xn-2…. x0 siv me ntsis-pair recoding hauv Booth's algorithm, ib nrab cov khoom tsim tawm raws li cov lus hauv qab no. Nqe lus piav qhia: ALU tsis tuaj yeem faib cov lej ncaj qha, nws tsuas tuaj yeem ntxiv, rho tawm lossis ua haujlwm.
Qhov twg yog qhov ua tau zoo dua thaum sib npaug lossis sib tw?
Counter flow heat exchangers yog qhov muaj txiaj ntsig ntau dua li qhov sib npaug ntawm cov khoom siv hluav taws xob sib txuas vim tias lawv tsim qhov sib txawv ntawm qhov sib txawv ntawm cov kua dej, dhau tag nrho qhov ntev ntawm cov kua dej.
Puas yog txhua qhov sib npaug sib npaug?
Yog, tag nrho peb tiam ntawm daim ntawv dawb tau raws nraim qhov loj me nrog tib lub pob layout. Siv tau rau rooj plaub raws li cov ntaub ntawv paperwhite haum rau txhua daim ntawv dawb, yav dhau los thiab tam sim no. Qhov ntsuas 6 nti yog hais txog qhov loj me ntawm lub vijtsam nkaus xwb, ntsuas ntawm kab pheeb ces kaum ntawm ib ces kaum mus rau lub kaum sab xis.
Thaum twg ob txoj kab uas tsis yog kab sib npaug sib npaug?
Ob txoj kab uas tsis sib xws yog qhov sib npaug yog tias lawv txoj kab nqes tib yam. Txhua ob kab ntsug yog sib npaug. Dab tsi yog ob kab Nonverttical sib npaug? Yog tias ob txoj kab tsis sib npaug sib npaug, ces lawv txoj kab nqes sib npaug.
Dab tsi yog qhov sib npaug ntawm kab rau kev sib raug zoo tsis sib haum?
Thaum nws los txog rau kev teeb tsa kev sib raug zoo tsis sib xws, nws yuav pab tau kom paub txog ob peb yam ntxwv ntawm kab zauv y=mx + b. Hauv kab zauv no, m yog sib npaug rau txoj kab nqes. Yuav ua li cas yog qhov sib npaug ntawm kev sib raug zoo?
