Phenolphthalein yog cov kua qaub tsis muaj zog thiab tsis muaj xim hauv cov tshuaj txawm tias nws ion yog liab … Ntxiv hydroxide ions hydroxide ions Hydroxide yog diatomic anion nrog tshuaj formula OH- Nws muaj cov pa oxygen thiab hydrogen atom tuav ua ke los ntawm ib qho kev sib cog lus, thiab nqa cov hluav taws xob tsis zoo. Nws yog ib qho tseem ceeb tab sis feem ntau me me ntawm cov dej. Nws ua haujlwm raws li lub hauv paus, ligand, nucleophile, thiab catalyst. https://en.wikipedia.org › wiki › Hydroxide
Hydroxide - Wikipedia
(OH-, raws li pom hauv hauv paus) yuav hloov cov phenolphthalein rau hauv nws cov ion thiab tig cov tshuaj liab.
Vim li cas cov xim liab ntawm phenolphthalein rov tshwm sim?
Kev piav qhia: Phenolphthalein yog qhov taw qhia yooj yim uas tsis muaj xim nyob rau hauv cov kua qaub thiab nruab nrab thiab hloov xim liab lossis magenta hauv cov tshuaj yooj yim. … (iii) Yog tias ob peb tee ntawm NaOH ntxiv rau tib cov tshuaj, cov tshuaj yuav ua tau yooj yim thiab cov xim liab ntawm cov phenolphthalein rov tshwm sim.
Dab tsi yog vim li cas rau kev hloov xim ntawm qhov ntsuas?
Kev hloov xim ntawm tus ntsuas pH yog ua los ntawm kev sib cais ntawm H+ ion los ntawm qhov ntsuas nws tus kheej Nco qab tias pH ntsuas tsis tsuas yog ntuj dyes tab sis kuj tsis muaj zog acids. Lub dissociation ntawm qhov tsis muaj zog acid qhia ua rau cov tshuaj hloov xim.
Vim li cas pH ntawv hloov xim?
Daim ntawv pH hloov xim hauv cov tshuaj pH sib txawv yog vim cov tshuaj FlavinCov molecule no, uas yog anthocyanin, yog soluble hauv dej thiab hloov xim nyob rau hauv muaj ntau yam. hom kev daws teeb meem. … Nyob rau hauv lub xub ntiag ntawm ib qho kev daws teeb meem, nws hloov lub teeb ntsuab.
Phenolphthalein hloov xim li cas?
Cov Acid & Base Cheebtsam ntawm Ammonium Chloride
Cov phenolphthalein qhov taw qhia tso cai rau cov kws tshuaj pom qhov muag pom tias cov tshuaj yog cov kua qaub lossis lub hauv paus. Cov xim hloov hauv phenolphthalein yog qhov tshwm sim ntawm ionization, thiab qhov no hloov cov duab ntawm phenolphthalein molecules.
