Titration txheej txheem

  1. 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.
  2. 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.

Ntawm no, dab tsi yog acid titration nrog piv txwv?

Rau piv txwv , hydrochloric kua qaub thiab sodium hydroxide daim ntawv sodium chloride thiab dej: HCl (aq) + NaOH (aq) → H2O (l) + NaCl (aq) Neutralization yog lub hauv paus ntawm titration . Qhov taw qhia pH qhia qhov sib npaug ntawm qhov sib npaug - qhov taw tes ntawm qhov sib npaug ntawm cov moles ntawm a puag tau ntxiv rau ib qho kua qaub.

Ib yam li ntawd, lub ntsiab lus ntawm acid puag titration yog dab tsi? Ib kua qaub – pib titration yog ib txoj hauv kev ntawm kev txheeb xyuas qhov ntau los txiav txim siab qhov concentration ntawm ib qho kua qaub los yog puag los ntawm raws nraim neutralizing nws nrog tus txheej txheem daws ntawm puag los yog kua qaub muaj kev paub concentration.

Ntxiv rau qhov no, lub hom phiaj ntawm acid puag titration yog dab tsi?

Taw qhia. Cov lub hom phiaj ntawm ib lub zog kua qaub - muaj zog pib titration yog txiav txim siab qhov concentration ntawm acidic tov los ntawm titrating nws nrog ib qho kev daws teeb meem ntawm kev paub concentration, los yog vice-versa, kom txog rau thaum neutralization tshwm sim.

Dab tsi yog qhov kawg point hauv titration?

Xaus Point . kawg point : cov taw tes thaum a titration thaum qhov taw qhia qhia tau hais tias tus nqi ntawm cov reactant tsim nyog rau kev ua tiav cov tshuaj tiv thaiv tau ntxiv rau kev daws.
