Ntchito ya SALS 3
Kuzindikira zotsatira za ayezi wouma (wozizira mpweya woipa) pa pH ndi Bromophenol blue
Zipangizo
- Pulogalamu ya SALS yotsitsidwa pa iPhone kapena iPad
- Chithunzi cha SALS
- Vernier Talking LabQuest
- Vernier pH kufufuza
- Owuma ayezi
- Bromophenol blue pH chizindikiro
- 750 ml ya madzi otentha
- Mankhwala otsitsa, kutengerapo pipette, kapena notched 1 ml syringe
- Galasi kapena chitsulo chogwedeza ndodo
- Madzi
- Magolovesi osatetezedwa

Chenjezo
Ophunzira ayenera kuvala magalasi otetezera panthawi yonseyi. Onetsetsani kuti magolovesi otsekera ali pafupi kuti mugwiritse ntchito madzi oundana.
Mayendedwe
- Thirani madzi mu beaker ya 750mL pafupi ndi theka.
- Onjezani madontho atatu odzaza (kapena mL imodzi yokhala ndi pipette kapena syringe) ya Bromophenol blue pH chizindikiro ku beaker ndikugwedeza ndi ndodo.
- Ikani beaker pa chitumbuwa kuti musakhale ndi kutaya komwe kungatayike.
- Ngati kuli kofunikira, konzani nsanja yokwezeka yokhala ndi mabuku kapena bokosi momwe mungakhazikitsire Talking LabQuest kuti muzitha kulowa mkati mwa beaker.
- Ikani kafukufuku wa SALS ndi Talking LabQuest pH probe mu beaker pafupi ndi mbali imodzi. Werengani ndi kafukufuku wa SALS, sungani mawu awa, ndikuyamba kusonkhanitsa deta pa Talking LabQuest.
- Kuvala magolovesi otetezedwa, gwiritsani ntchito nyundoyo kuti muphwanye ayezi wouma kukhala chipika cha kukula kwa nkhonya.
- Magolovesi akadali, nyamulani chidutswa cha ayezi wouma ndikuchiponya mu beaker kutali ndi masensa momwe mungathere. Ngati pakufunika kutero, gwirani masensa kumbali imodzi ndikupendekera beaker mbali ina mpaka madzi oundana agunda mbali ina ya beaker. Izi zikatha, ikaninso beaker mu chitini cha chitumbuwa kachiwiri.
- Mvetserani kusintha kwa kamvekedwe mu SALS ndi kusintha kwa pH komwe kudalengezedwa ndi Talking LabQuest kuti mudziwe pamene mtundu wa Bromophenol blue pH chizindikiro chasintha.
Mafunso oti muyankhe
- Kodi mukuganiza kuti mtunduwo unasintha pa pH yanji?
- Kodi bromophenol buluu imasonyeza yankho kukhala acidic kwambiri kapena zofunika kwambiri?
- Kodi kuwonjezera madzi oundana m'madzi kunakhudza bwanji?
