Izinto zokwakha namathuluzi adingekayo
1. Isitashi esincibilikayo
2. I-asidi ye-sulfuric egxilile
3. I-Beaker engu-2000ml
4. I-beaker engu-350ml
5. Iphepha lokukala kanye nezikali ze-elekthronikhi
6. Amanzi ahlanzekile
7. I-reagent yokuhlaziya ye-sodium thiosulfate
Ukulungiselela isisombululo sesitoko se-sodium thiosulfate
Kala amanzi ahlanzekile angu-1000ml ngokusebenzisa izinkomishi zokulinganisa ezingu-500ml kabili bese uwathela emshinini wokugaya amanzi ongu-2000ml.
Bese uthela ibhodlela lonke le-sodium thiosulfate analytical reagent ebhekheni ngqo, Beka ibhekheni esitofini sokungenisa kuze kube yilapho ikhambi libila imizuzu eyishumi.
Ngemva kwalokho, Gcina kupholile, futhi kuthule amasonto amabili, bese uyihluza ukuze uthole isisombululo se-sodium thiosulfate.
Ukulungiselela i-1+5 sulfuric acid
Kala amanzi ahlanzekile angu-750ml ngokusebenzisa indebe yokulinganisa engu-500ml kabili bese uwathela ebhodleleni elingu-1000ml elinomlomo wasendle.
Bese ulinganisa i-asidi ye-sulfuric egxilile engu-150ml, Thela i-asidi emanzini ahlanzekile kancane, Yixube ngaso sonke isikhathi uma uthulula.
Lungisa isisombululo sesitashi esingu-10g/L
Kala amanzi ahlanzekile ayi-100ml ngokusebenzisa indebe yokulinganisa eyi-100ml, bese uwathela ebhekheni elingama-300ml.
Kala i-1g yesitashi esincibilikayo ngesikali se-elekthronikhi, bese usifaka ku-50ml ye-beaker. Thatha i-300ml ye-beaker esitofini sokungenisa amanzi ukuze ubilise amanzi.
Thela amanzi amancane ahlanzekile ukuze uncibilikise isitashi, Bese uthela isitashi esincibilikisiwe emanzini abilayo ahlanzekile, Gcina kupholile ukuze kusetshenziswe.
Izinyathelo zokulinganisa okuqukethwe yi-Trichloroisocyanuric acid
Thatha amanzi ahlanzekile ayi-100ml Ebhodleleni le-iodine elingu-250ml.
Kala isampula ye-TCCA engu-0.1g ngesikali sokunemba, Yenza kube yi-0.001g, Faka isampula ngqo ebhodleleni le-iodine elingu-250ml.
Kala u-2g we-potassium iodide ebhodleleni le-iodine, bese ufaka ku-20ml we-20% sulfuric acid, bese uvala ibhodle ngamanzi ngemva kokuhlanza intamo yebhodle ngokuhlanza ibhodle.
Yenza kube yi-ultrasonic wave. Yincibilikise ngokuphelele, Ngemva kwalokho, hlanza intamo yebhodlela usebenzisa amanzi ahlanzekile futhi.
Isinyathelo sokugcina ukufaka i-titration ngesisombululo se-titration esijwayelekile se-Sodium thiosulfate, kuze kube yilapho isixazululo sinombala ophuzi okhanyayo faka i-2ml starch tracer agent. Bese uqhubeka nokufaka i-titration kuze kube yilapho umbala oluhlaza okwesibhakabhaka unyamalala. Bese singakuqeda.
Qopha ivolumu ye-sodium thiosulfate esetshenzisiwe
Yenza ukuhlolwa okumnyama ngesikhathi esifanayo
Ukubala inqubo yemiphumela yokuhlola
