Ịkpachara anya
Ụmụ akwụkwọ ga-eyi enyo nchekwa n'ime usoro niile. Gbaa mbọ hụ na uwe mkpuchi mkpuchi dị nso maka ijikwa ice kpọrọ nkụ.
Ntuziaka
- Jupụta mmiri 750 ml ihe dị ka ọkara ọkara.
- Tinye 3 droppers zuru ezu (ma ọ bụ otu ml nwere pipette ma ọ bụ sirinji mbufe) nke Bromophenol blue pH egosi na beaker wee kpalie ya na mkpara na-akpali akpali.
- Tinye beaker n'elu tin achịcha ka ọ nwee ike ịwụfu.
- Ọ bụrụ na ọ dị mkpa, dozie ikpo okwu dị elu nke nwere akwụkwọ ma ọ bụ igbe nke ị ga-ezu ike na Talking LabQuest iji kwado ohere ịbanye n'ime beaker.
- Debe nyocha SALS na nyocha Talking LabQuest pH na beaker dị nso n'otu akụkụ. Were nyocha SALS gụọ akwụkwọ, chekwaa ụda a, wee malite nchịkọta data na Talking LabQuest.
- N'iji aka mkpuchi mkpuchi, jiri hama mebie ice kpọrọ nkụ n'ime ihe dị ka oke aka.
- Ka uwe aka ahụ ka dị, bulie mpempe ice kpọrọ nkụ wee tụba ya na beaker ka ọ dị anya na sensọ dị ka o kwere mee. Ọ bụrụ na ọ dị mkpa, jide sensọ n'otu akụkụ ma tie beaker n'akụkụ nke ọzọ ruo mgbe ice kpọrọ nkụ dara n'akụkụ nke ọzọ nke beaker. Ozugbo emechara nke a, tinye beaker ahụ n'ụzọ dị larịị na tin achịcha ọzọ.
- Gee ntị maka mgbanwe ụda na SALS na pH mgbanwe nke Talking LabQuest mara ọkwa iji chọpụta mgbe agba nke Bromophenol blue pH egosi gbanwere.
Ajụjụ ịza
- Kedu pH ị chere na agba gbanwere?
- Bromophenol acha anụnụ anụnụ na-egosi ngwọta na-aghọ acidic ma ọ bụ karịa?
