Izinhlelo zokusebenza ze-SALS App
Umsebenzi we-SALS 3
Ithola umthelela weqhwa elomile (i-carbon dioxide eqandisiwe) ku-pH nge-Bromophenol eluhlaza okwesibhakabhaka
Izinto zokwakha
- Uhlelo lokusebenza lwe-SALS lulandwe ku-iPhone noma ku-iPad
- Uphenyo lwe-SALS
- I-Vernier Talking LabQuest
- I-Vernier pH probe
- Iqhwa elomile
- I-Bromophenol blue pH inkomba
- 750 mL ibhodlela
- I-dropper yomuthi, i-pipette yokudlulisa, noma isirinji engu-1 mL enophawu
- Ingilazi noma insimbi enyakazayo
- Amanzi
- Amagilavu afakiwe
- Isando
- Ithini likaphayi
- Izincwadi zokufunda noma ibhokisi eliqinile lokudala inkundla ephakanyisiwe
- Izibuko zokuphepha
Isexwayiso
Abafundi kumele bagqoke izibuko zokuphepha kuyo yonke inqubo. Qinisekisa ukuthi amagilavu afakwe i-insured aseduze ukuze ubambe iqhwa elomile.
Izikhombisi-ndlela
- Gcwalisa ibhekha elingu-750mL cishe phakathi nendawo ngamanzi.
- Engeza amaconsi ama-3 agcwele (noma i-mL eyodwa enepipette yokudlulisa noma isirinji) ye-Bromophenol blue pH indicator kubhekha futhi ushukumise ngentonga enyakazayo.
- Beka ibhika ethini likaphaya ukuze kungabi nokuchitheka okungenzeka.
- Uma kudingekile, lungiselela inkundla ephakanyisiwe enezincwadi noma ibhokisi lapho kuzobekwa khona i-Talking LabQuest ukuze kube lula ukufinyelela ngaphakathi kwebhekha.
- Beka i-SALS probe kanye ne-Talking LabQuest pH probe ebhekheni eduze kohlangothi olulodwa. Funda ngophenyo lwe-SALS, londoloza le toni, bese uqala ukuqoqwa kwedatha ku-Talking LabQuest.
- Ugqoke amagilavu avaliwe, sebenzisa isando ukuze uhlephule iqhwa elomile libe yibhlokhi elilingana nesibhakela.
- Njengoba amagilavu esavuliwe, thatha ucezu lweqhwa elomile bese uliphonsa ebhekhani kude kakhulu nezinzwa. Uma kudingeka, bamba izinzwa ohlangothini olulodwa bese utshekisa ibhikha ohlangothini oluphambene kuze kube yilapho iqhwa elomile lishaya ngakolunye uhlangothi lwebhekha. Uma lokhu sekwenziwe, beka ibhekha isicaba ethini likaphaya futhi.
- Lalela ukushintsha kwethoni ku-SALS kanye noshintsho lwe-pH olumenyezelwe i-Talking LabQuest ukuze unqume ukuthi umbala wenkomba ye-pH eluhlaza okwesibhakabhaka i-Bromophenol ushintshe nini.
Imibuzo okumele uyiphendule
- Ucabanga ukuthi umbala ushintshe ngayiphi i-pH?
- Ingabe i-bromophenol eluhlaza okwesibhakabhaka ibonisa isixazululo esiba ne-asidi kakhulu noma esiyisisekelo?
- Ukufaka iqhwa elomile emanzini kube namuphi umphumela?
