3. Ukuqinisekiswa koMxholo weCalcium Formate
3.1 Isishwankathelo seNdlela yeCalcium Formate: Kwisisombululo se-calcium formate esine-alkaline kancinci, yongeza isisombululo esingaphezulu kwesisombululo esiqhelekileyo se-potassium permanganate. Fudumeza ukuqinisekisa ukuba impendulo ye-oxidation iyaqhubeka iphela. I-potassium permanganate engaphezulu iya kukhulula i-iodine kwi-potassium iodide kwisisombululo esine-asidi, ize emva koko ixutywe nesisombululo esiqhelekileyo se-sodium thiosulfate.
3.2 Amanyathelo okuchonga iCalcium Formate: Linganisa malunga ne-0.4g yesampuli ye-calcium formate (echanekileyo ukuya kwi-0.0002g), yibeke kwiflaski ye-250ml yevolumu, uyinyibilikise emanzini, uyixube kakuhle, kwaye uyishukumise kakuhle. I-Pipette 25.00ml (okanye i-10ml) yesi sicombululo kwiflaski ye-iodine, yongeza i-0.2g ye-sodium carbonate engamanzi, kwaye uyishukumise kakuhle. Yongeza ngokuchanekileyo i-50.00ml (okanye i-20ml) yesisombululo esiqhelekileyo se-potassium permanganate, uyifudumeze emanzini imizuzu engama-30, uze uyipholise. Yongeza i-6ml yesisombululo se-sulfuric acid kunye ne-2g ye-potassium iodide, yiyeke ime ebumnyameni imizuzu emi-5. Yixube ngesisombululo esiqhelekileyo se-sodium thiosulfate; kufutshane nendawo yokugqibela, yongeza i-3ml yesalathisi sesitatshi (0.5%), kwaye uqhubeke ushukumise ude umbala oluhlaza okwesibhakabhaka uphele. Yenza uvavanyo olungenanto ngaxeshanye.
