Titration ntawm a tsis muaj zog puag nrog a muaj zog acid . Hauv ib tsis muaj zog puag - muaj zog acid titration , cov kua qaub thiab puag yuav teb rau daim ntawv acidic daws. Ib conjugate kua qaub yuav raug tsim thaum lub sij hawm titration , uas ces reacts nrog dej los tsim hydronium ions. Qhov no ua rau muaj kev daws teeb meem nrog pH qis dua 7.

Tsis tas li ntawd, thaum lub zog acid yog titrated nrog lub hauv paus tsis muaj zog pH ntawm qhov sib npaug?

Cov sib npaug point hauv titration ntawm ib lub zog kua qaub los yog muaj zog puag tshwm sim ntawm pH 7.0 ib. Hauv titrations ntawm tsis muaj zog acids los yog tsis muaj zog hauv paus , txawm li cas los xij, cov pH ntawm qhov sib npaug yog ntau dua los yog tsawg dua 7.0, feem.

Ib tug kuj yuav nug, uas yog qhov zoo tshaj plaws kev xaiv rau qaug zog acid titration? Yog hais tias ib qho tshuaj qhia tau siv-methyl txiv kab ntxwv yuav yog xaiv zoo nyob rau hauv cov ntaub ntawv no - nws hloov los ntawm nws qhov pib mus rau nws acidic xim. Titration ntawm a tsis muaj zog puag nrog a muaj zog acidA depiction ntawm pH hloov thaum lub sij hawm a titration ntawm HCl daws rau hauv ammonia daws.

Raws li txoj cai, koj puas tuaj yeem titrate lub hauv paus muaj zog nrog cov kua qaub tsis muaj zog?

Hauv titration ntawm a qaug zog acid nrog a lub hauv paus muaj zog , lub conjugate puag ntawm tsis muaj zog acid yuav ua kom pH ntawm qhov sib npaug ntawm qhov sib npaug ntau dua 7. Yog li ntawd, koj yuav xav tau ib qho taw qhia kom hloov pauv ntawm qhov pH.

Puas yog NaOH lub hauv paus muaj zog lossis tsis muaj zog?

Sodium hydroxide ( NaOH ) yog lub hauv paus muaj zog vim nws tag nrho dissociates hauv dej los tsim hydroxide ions. Thaum ammonia (NH3) yog tsis muaj zog puag vim tias nws txais cov protons los ntawm dej los tsim cov hydroxide ions tsawg dua hauv cov tshuaj. Thaum tsis muaj zog hauv paus tsim cov hydroxide ions tsawg dua, ua rau kev daws teeb meem tsawg dua.
