Phenol liab yog ib ph qhia tias yuav yog txiv kab ntxwv ntawm. Phenol liab yog ib pH qhia tias yuav yog txiv kab ntxwv ntawm nruab nrab pH ; daj nyob rau hauv acidic ib puag ncig thiab tsaus liab nyob rau hauv ib puag ncig yooj yim.
Yog li ntawd, dab tsi xim yog phenol liab nyob rau hauv ib qho kev daws teeb meem?
Phenol liab yog ib pH qhov taw qhia nquag siv hauv cell biology kuaj. Nws cov xim nthuav tawm ib qho kev hloov maj mam los ntawm daj rau liab dhau lub pH 6.8 rau 8.2. Saum toj no pH 8.2, phenol liab hloov lub ci liab ( fuchsia ) xim.
Qhov thib ob, nws txhais li cas thaum phenol liab tig daj? Phenol liab yog pH qhov taw qhia uas yog daj ntawm pH hauv qab 6.8 thiab liab ntawm pH saum toj no 7.4 nrog sib txawv ntxoov los ntawm daj rau liab nruab nrab ntawm cov qib pH. Yog tias qhov ntsuas tau tig daj hauv lub raj mis no txhais tau tias Nws tau dhau los ua paug nrog qee yam uas ua rau pH ntau acidic thiab coj pH qis dua 6.8.
Ib sab saum toj no, dab tsi xim phenol liab tig nyob rau hauv acidic mob?
Phenol liab yog dej-soluble dye siv raws li pH qhia, hloov los ntawm daj kom liab dhau pH 6.6 txog 8.0, thiab tom qab ntawd tig a ci liab xim saum toj no pH 8.1.
Dab tsi ua rau xim hloov hauv phenol liab?
Cov phenol liab hloov xim thaum koj tshuab rau nws, vim koj tab tom qhia cov pa roj carbon dioxide rau qhov sib tov. Phenol liab hloov kom daj nyob rau hauv pH qis dua 7, yog li qhov kev daws teeb meem tig daj yog qhov qhia txog acidic (qis dua 7 pH).

Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Dab tsi xim yog phenol liab nyob rau hauv ib qho kev daws teeb meem?
Phenol liab yog cov kua qaub-puag qhia. Nws yog tsim los ntawm condensing ob moles ntawm phenol nrog ib tug mole ntawm o-sulfobenzoic acid anhydride. Phenol Liab yog siv los ua pH qhia hauv daim ntawv thov kab lis kev cai ntawm tes. Kev daws ntawm phenol liab yuav muaj xim daj ntawm pH ntawm 6.4 lossis qis dua thiab xim liab ntawm pH
Dab tsi yog qee cov kua qaub hauv tsev thiab cov hauv paus?
Daim ntawv teev cov tsev Bases & Acids Baking Soda. Baking soda yog lub npe nrov rau sodium bicarbonate, paub tshuaj raws li NaHCO3. Diluted Soaps. Tsev neeg Ammonia. Tsev Neeg Vinegar. Citric Acid
Cov xim dab tsi yog cov hlwb feem ntau ua ntej siv thawj cov xim rau cov txheej txheem Gram stain?
Ua ntej, siv lead ua violet, thawj stain, yog siv rau lub tshav kub-tso smear, muab tag nrho cov hlwb xim liab
Cov piv txwv ntawm tsev neeg cov kua qaub thiab cov hauv paus yog dab tsi?
Daim ntawv teev cov tsev Bases & Acids Baking Soda. Baking soda yog lub npe nrov rau sodium bicarbonate, paub tshuaj raws li NaHCO3. Diluted Soaps. Tsev neeg Ammonia. Tsev Neeg Vinegar. Citric Acid
