3. Ukuqunta Okuqukethwe Kwe-Calcium Formate
3.1 Indlela ye-Calcium Formate Ukuhlolisisa: Esixazululweni se-calcium formate esine-alkaline kancani, faka isisombululo esijayelekileko se-potassium permanganate. Ukutjhisa ukuqinisekisa bona ukusabela kwe-oksijini kuyaragela phambili. I-potassium permanganate eyengeziweko izokukhulula i-iodine ku-potassium iodide esixazululweni esine-esidi, ebese sitjhugululwa ngesisombululo esijayelekileko se-sodium thiosulfate.
3.2 Amagadango wokuThola i-Calcium Formate: Kala pheze i-0.4g yesampula ye-calcium formate (eqondileko ukuya ku-0.0002g), uyifake ngaphakathi kweflaski yevolumu engu-250ml, uyincibilikise emanzini, uyincibilikise ukuya ephawu, bese uyithintitha kuhle. Faka i-25.00ml (nofana i-10ml) yesixazululo ngaphakathi kweflaski ye-iodine, faka i-0.2g ye-anhydrous sodium carbonate, bese uthintitha kuhle. Faka ngokunembileko i-50.00ml (nofana i-20ml) yesixazululo esijayelekileko se-potassium permanganate, ufuthumeze emanzini imizuzu ema-30, bese uyapholisa. Faka i-6ml yesixazululo se-sulphuric acid kanye ne-2g ye-potassium iodide, uyiyekele ibe sebumnyameni imizuzu emi-5. Titrate ngesisombululo esijayelekileko se-sodium thiosulfate; eduze nendawo yokuphela, faka i-3ml yesitatjhi esibonisako (0.5%), bese uragela phambili nokutjhugulula bekube lapho umbala ohlaza satjani unyamalala khona. Yenza ukuhlolwa okungenalutho ngasikhathi sinye.
