3. Kutsimikiza Kuchuluka kwa Calcium Formate
3.1 Chidule cha Njira ya Calcium Formate: Mu yankho la calcium formate lokhala ndi alkaline pang'ono, onjezerani yankho lowonjezera la potassium permanganate. Tenthetsani kuti muwonetsetse kuti ma oxidation reaction apitirira mpaka kumapeto. Potassium permanganate yochulukirapo idzatulutsa ayodini kuchokera ku potassium iodide mu yankho la acidic, lomwe kenako limathiridwa ndi sodium thiosulfate standard solution.
3.2 Njira Zodziwira Calcium Formate: Yesani pafupifupi 0.4g ya chitsanzo cha calcium formate (cholondola mpaka 0.0002g), ikani mu botolo la 250ml volumetric, isungunuleni m'madzi, isungunulani mpaka chizindikirocho chifike, ndikugwedeza bwino. Pipette 25.00ml (kapena 10ml) ya yankho ili mu botolo la ayodini, onjezerani 0.2g ya sodium carbonate ya anhydrous, ndikugwedeza bwino. Onjezani molondola 50.00ml (kapena 20ml) ya yankho la potassium permanganate, itentheni mu bafa la madzi kwa mphindi 30, kenako muziziziritse. Onjezani 6ml ya yankho la sulfuric acid ndi 2g ya potassium iodide, musiye mumdima kwa mphindi 5. Thirani ndi yankho la sodium thiosulfate standard; pafupi ndi mapeto, onjezani 3ml ya starch indicator (0.5%), ndipo pitirizani kuthira mpaka mtundu wabuluu utatha. Chitani mayeso opanda kanthu nthawi imodzi.

Dziwani zabwino zosagonjetseka za calcium formate—onjezerani magwiridwe antchito a malonda anu ndikuchepetsa ndalama! Mukufuna kudziwa zambiri? Dinani kuti mufunse tsopano kuti mupeze mayankho okonzedwa bwino!
