3. Ukunqunywa Kokuqukethwe kwe-Calcium Formate
3.1 Ukubuka Konke Kwendlela Ye-Calcium Formate: Esixazululweni se-calcium formate esine-alkaline kancane, engeza isixazululo esijwayelekile se-potassium permanganate. Fudumeza ukuqinisekisa ukuthi ukusabela kwe-oxidation kuyaqhubeka kuze kube sekuqedweni. I-potassium permanganate eningi izokhipha i-iodine ku-potassium iodide esixazululweni esine-acidic, bese ifakwa i-tit ngesisombululo esijwayelekile se-sodium thiosulfate.
3.2 Izinyathelo Zokunquma I-Calcium Formate: Kala cishe isampula ye-calcium formate engu-0.4g (enembile ku-0.0002g), uyibeke ebhodleleni elingu-250ml, uyincibilikise emanzini, uyixube kahle, bese uyixuba kahle. Faka i-Pipette engu-25.00ml (noma u-10ml) walesi sixazululo ebhodleleni le-iodine, engeza u-0.2g we-sodium carbonate engamanzi, bese uyixuba kahle. Faka ngokunembile isixazululo esijwayelekile se-potassium permanganate esingu-50.00ml (noma u-20ml), uyifudumale emanzini okugeza imizuzu engama-30, bese uyipholisa. Faka isixazululo se-sulfuric acid esingu-6ml kanye no-2g we-potassium iodide, uyivumele ime ebumnyameni imizuzu emi-5. Faka i-Titrate ngesisombululo esijwayelekile se-sodium thiosulfate; eduze nendawo yokugcina, engeza i-3ml ye-starch indicator (0.5%), bese uqhubeka nokuxuba kuze kube yilapho umbala oluhlaza okwesibhakabhaka unyamalala. Yenza isivivinyo esingenalutho ngasikhathi sinye.
