3. Kuncuma Lokucuketfwe Kwe-Calcium Formate
3.1 Indlela Yekukhicita I-Calcium Sibutsetelo: Kusisombululo se-calcium formate lesine-alkaline kancane, faka sisombululo lesijwayelekile se-potassium permanganate lengetulu. Kushisa kucinisekisa kutsi kuphendvula kwe-oxidation kuyachubeka kuze kuphele. Le potassium lengetulu itawukhulula iodine kusuka ku potassium iodide ngesisombululo lesine esidi, lese iyahlanganiswa ngesisombululo lesijwayelekile se sodium thiosulfate.
3.2 Tinyatselo Tekuncuma I-Calcium Formate:Kala cishe 0.4g wesampula ye-calcium formate (lenembile kuya ku 0.0002g), uyifake eflaskini lelingu 250ml, uyincibilikise emantini, uyihlanjulule kuze kube sesigabeni, bese uyayinyakatisa kahle. Pipette 25.00ml (noma 10ml) walesisombululo ube yiflaski ye-iodine, faka 0.2g we-sodium carbonate lengenamanti, bese uyanyakatisa kahle. Faka 6ml wesixazululo se sulfuric acid kanye na 2g we potassium iodide, uvumele kutsi ume ebumnyameni imizuzu lesihlanu. Titrate ngesisombululo lesijwayelekile se-sodium thiosulfate; edvute nendzawo yekugcina, faka 3ml wesikhombi sesitashi (0.5%), bese uchubeka neku titrate kuze kube ngulapho umbala loluhlata sasibhakabhaka unyamalala. Yenta sivivinyo lesingenalutfo ngaso sonkhe sikhatsi.

Tfola tinzuzo letingeke tehlulwe te-calcium formate—khutsata kusebenta kwemkhicito wakho futsi unciphise tindleko! Uyafuna kufundza kabanti? Chafata kute ubute nyalo kute utfole tisombululo letilungiselelwe wena!
