3. Ku kumiwa ka Nhlayo ya Xivumbeko xa Calcium
3.1 Nkatsakanyo wa Ndlela ya Calcium Formate: Eka xitofu xa calcium formate lexi nga na alkaline nyana, chela ku tlula mpimo ka potassium permanganate standard solution. Hisisa kutiyisisa leswaku oxidation reaction yiya emahlweni kuya fika eku hetiseni. Potassium permanganate leyi tlulaka mpimo yita ntshunxa iodine kusuka eka potassium iodide eka acidic solution, leyi endzhaku yi titrated hi sodium thiosulfate standard solution.
3.2 Magoza yo kumisisa Calcium Formate:Pima kwalomu ka 0.4g ya xikombiso xa calcium formate (leyi lulameke kufika eka 0.0002g), yi veka eka 250ml volumetric flask, yi n’okisela ematini, yi chela kufikela eka mfungho, kutani u rhurhumela kahle. Pipette 25.00ml (kumbe 10ml) ya solution leyi eka iodine flask, chela 0.2g ya anhydrous sodium carbonate, kutani u rhurhumela kahle.Hi ku kongoma chela 50.00ml (kumbe 20ml) ya potassium permanganate standard solution, hisa eka water bath kuringana 30 wa timinete, kutani u titimela. Engeta 6ml ya sulfuric acid solution na 2g ya potassium iodide, yi tshika yi yima emunyameni kuringana 5 wa timinete. Titrate hi sodium thiosulfate standard solution; ekusuhi na makumu, chela 3ml ya starch indicator (0.5%), kutani u ya emahlweni u titrating kufikela loko muhlovo wa wasi wu nyamalala. Endla xikambelo lexi nga riki na nchumu hi nkarhi wun’we.
