Lub hom phiaj ntawm a muaj zog acid - muaj zog puag titration yog txiav txim siab qhov concentration ntawm acidic tov los ntawm titrating nws cu a yooj yim daws ntawm paub concentration, los yog vice versa, kom txog rau thaum neutralization tshwm sim . Yog li ntawd, cov tshuaj tiv thaiv ntawm a muaj zog acid thiab lub hauv paus muaj zog yuav ua rau dej thiab ntsev.
Ib yam li ntawd, yuav ua li cas tshwm sim thaum lub zog acid reacts nrog lub hauv paus muaj zog?
Qhov tseeb, thaum a muaj zog acid reacts nrog lub hauv paus muaj zog , cov khoom tshwm sim yog dej thiab ntsev ionic. Lwm qhov piv txwv ntawm xws li a tshuaj tiv thaiv yog tshuaj tshuaj tiv thaiv nruab nrab ntawm hydrochloric kua qaub (HCl) thiab potassium hydroxide (KOH).
Ib yam li ntawd, nws puas siv ntau lub hauv paus los ua kom muaj zog acid? Muaj zog acids yuav neutralize lub hauv paus muaj zog ntawm qhov sib npaug ntawm qhov sib npaug ntawm qhov sib npaug. Ntau ntim ntawm qaug zog kua qaub yog xav tau neutralize lub hauv paus muaj zog yog hais tias cov concentrations sib npaug thiab vise versa rau qaug zog hauv paus thiab muaj zog acids . Ib qho tsis yog ib qho kev daws teeb meem uas muaj qhov tsis muaj zog kua qaub thiab ntsev nrog tib lub anion li tus kua qaub.
Nyob rau hauv kev hwm rau qhov no, yuav ua li cas tshwm sim thaum koj titrate ib tug qaug zog acid nrog ib tug muaj zog puag?
Hauv titration ntawm a qaug zog acid nrog lub hauv paus muaj zog , lub conjugate puag ntawm qaug zog acid yuav ua rau pH ntawm qhov sib npaug point ntau dua 7. Yog li ntawd, koj xav tau ib qho taw qhia hloov pauv hauv qhov pH ntau.
Puas yog NaOH lub hauv paus tsis muaj zog?
Sodium hydroxide ( NaOH ) muaj zog puag vim nws tag nrho dissociates hauv dej los tsim hydroxide ions. Thaum ammonia (NH3) yog tsis muaj zog puag vim nws txais cov protons los ntawm dej los tsim tsawg hydroxide ions nyob rau hauv kev daws. Thaum tsis muaj zog hauv paus tsim cov hydroxide ions tsawg dua, ua rau kev daws teeb meem tsawg dua.

Yuav ua li cas tshwm sim thaum Ethanoic acid reacts nrog dilute tov ntawm sodium hydroxide?
Thaum ethanoic acid reacts nrog sodium hydroxide nws tsim brisk effervescense ntawm co2 thiab dej thiab sodium ethanoate. Qhov no yog ib hom tshuaj tiv thaiv neutralization. Nws tsim CH3COONa (Sodium ethanoate lossis sodium acetate) thiab dej (H2O)
Yuav ua li cas tshwm sim rau tus nqi sib npaug thiab ntau npaum li cas thaum muaj kev nce ntxiv hauv kev thov thiab nce hauv cov khoom?
Qhov kev thov nce ntxiv, txhua yam tsis hloov pauv, yuav ua rau tus nqi sib npaug nce; cov khoom siv yuav nce ntxiv. Kev txo qis hauv kev thov yuav ua rau tus nqi sib npaug; kom muaj nuj nqis yuav txo. Kev txo qis hauv cov khoom yuav ua rau tus nqi sib npaug nce; kom muaj nuj nqis yuav txo
Yuav ua li cas tshwm sim thaum ib tug ntawm cov neeg xauj tsev ib txwm xav muag?
Pom Zoo Muag Vim tias lawv tsis muaj tag nrho cov cuab yeej, ib tus neeg xauj tsev tsis tuaj yeem muag tag nrho cov av lossis ib lub tsev yam tsis tau kev tso cai los ntawm txhua tus tswv cuab. Yog tias, txawm li cas los xij, tag nrho cov tswv cuab koom ua ke pom zoo, cov cuab yeej tuaj yeem mus rau hauv khw thiab muag
Yuav ua li cas tshwm sim thaum thawj zaug thiab thib ob ua liaj ua teb kiv puag ncig?
Lub Ntiaj Teb Kev Ua Liaj Ua Teb Thib Ob, tseem hu ua British Agricultural Revolution, tau tshwm sim thawj zaug hauv tebchaws Askiv nyob rau xyoo kaum xya thiab kaum yim xyoo pua. Nws koom nrog kev qhia txog kev hloov qoob loo tshiab thiab xaiv kev yug tsiaj txhu, thiab ua rau muaj kev nce qib hauv kev ua liaj ua teb
Vim li cas cov duab ntawm titration nkhaus txawv rau titration ntawm muaj zog acid vs muaj zog puag thiab qaug zog acid vs muaj zog puag?
Cov duab dav dav ntawm titration nkhaus yog tib yam, tab sis pH ntawm qhov sib npaug sib txawv. Hauv qhov tsis muaj zog acid-muaj zog titration, pH yog ntau dua 7 ntawm qhov sib npaug. Hauv qhov muaj zog acid-tsis muaj zog titration, pH tsawg dua 7 ntawm qhov sib npaug
