Quinaldine liab yog qhov taw qhia uas hloov los ntawm tsis muaj xim mus rau xim liab ntawm pH ntawm 1.0–2.2.
Qhov ntsuas twg yog siv rau hauv alkali metric tsis aqueous titration?
Qhov taw qhia tseem ceeb siv rau kev tsis muaj dej titration yog follow:- 1. Crystal voilet: - Nws yog siv los ua 0.5% tov hauv glacial acetic acid, nws muab voilet xim nyob rau hauv nruab nrab nruab nrab thiab yellowish ntsuab nyob rau hauv acidic nruab nrab.
Qhov twg ntawm cov no tsis yog qhov taw qhia rau cov dej tsis muaj dej?
moisutre thiab carbon dioxide yuav tsum zam hauv txoj kev tsis muaj dej. cov ntsuas siv nyob rau hauv tsis aqueous titration. Crystal Violet. 0.5% w/v daws nyob rau hauv glacial acetic acid.
Vim li cas acetic anhydride ntxiv thaum npaj cov tshuaj perchloric acid MCQ?
Tus perchloric acid yuav tsum tau diluted nrog acetic acid ua ntej ntxiv cov acetic anhydride tsis ua hauj lwm los saib xyuas qhov kev ceev faj no ua rau tsim cov khoom tawg acetyl perchlorate.
Dab tsi ntxiv thaum npaj cov tshuaj perchloric acid?
Perchloric acid Solution Preparation
Ncua li 500 ml ntawm anhydrous glacial acetic acid & txog 25 ml Acetic anhydride nyob rau hauv ib tug huv thiab qhuav 1000 ml volumetric hwj. Ntxiv li 8.5 ml ntawm Perchloric acid (txog 70%) nrog txuas ntxiv stirring. Txias txoj kev daws.
