3. Calcium Formate Content Determination
3.1 Calcium Formate Method Overview: I calcium formate ma alkaline nyanok, med potassium permanganate ma ukadhu. Lyeth pi neno nia oxidation reaction umedire maber. Potassium permanganate ma ukadhu biwodho iodine kud i potassium iodide i pii ma acid, ma jubi loko ku sodium thiosulfate.
3.2 Yore mi nyang ikum Calcium Formate:Pim 0.4g pa calcium formate (ma rwate ku 0.0002g), iket i 250ml volumetric flask, ilok i pii, ilok i rwom, man i yenge maber. Pipette 25.00ml (nyo 10ml) pa pii eni i iodine flask, med 0.2g pa anhydrous sodium carbonate, man yeng maber. Med 50.00ml (nyo 20ml) pa potassium permanganate standard solution, lyeth i pii pi dakika 30, man idok ngic. Med 6ml pa sulfuric acid man 2g pa potassium iodide, wek ebed i mudho pi dakika abic. Titrate ku sodium thiosulfate standard solution; kago ku thum, med 3ml pa lanyuth pa starch (0.5%), man mediri ku titrating nitundo ma rangi macol uthum. Tim penji ma goro i saa acel.

Nwangu bero pa calcium formate—medu tic peri maber man jwigo wel piny peri! Imito ngeyo lembe mukende? Dii pi penjo kawoni pi adwogi maber!
