3. Ho Fumana Dikahare tsa Calcium Formate
3.1 Kakaretso ea Mokhoa oa Calcium Formate: Tharollong ea calcium formate e nang le alkaline e nyane, eketsa tharollo e feteletseng ea potassium permanganate. Chesa ho netefatsa hore karabelo ea oxidation e tsoela pele ho fihlela qetellong. Potassium permanganate e feteletseng e tla lokolla iodine ho potassium iodide ka har'a tharollo ea asiti, ebe e kenngoa ka tharollo e tloaelehileng ea sodium thiosulfate.
3.2 Mehato ea ho Fumana Calcium Formate: Bekha hoo e ka bang 0.4g ea sampole ea calcium formate (e nepahetseng ho 0.0002g), e behe ka har'a flask ea volumetric ea 250ml, e qhale ka metsing, e qhibilihe ho fihlela letšoao, 'me u sisinye hantle. Pipette 25.00ml (kapa 10ml) ea tharollo ena ka har'a flask ea iodine, eketsa 0.2g ea sodium carbonate e sa hloekang, 'me u sisinye hantle. Kenya 50.00ml (kapa 20ml) ea tharollo e tloaelehileng ea potassium permanganate ka nepo, u e futhumatse ka bateng ea metsi metsotso e 30, ebe u e pholile. Kenya 6ml ea tharollo ea sulfuric acid le 2g ea potassium iodide, e tlohele e eme lefifing metsotso e 5. Tshisa ka tharollo e tloaelehileng ea sodium thiosulfate; haufi le pheletso, eketsa 3ml ea starch indicator (0.5%), 'me u tsoele pele ho tsitsa ho fihlela' mala o moputsoa o nyamela. Etsa teko e se nang letho ka nako e le 'ngoe.

Sibolla melemo e ke keng ea hlōloa ea calcium formate—eketsa ts'ebetso ea sehlahisoa sa hau 'me u fokotse litšenyehelo! Na u labalabela ho tseba ho eketsehileng? Tobetsa ho botsa hona joale bakeng sa litharollo tse etselitsoeng uena!
