3. Kwano gin ma tye i Calcium Formate
3.1 Kit me yubu Calcium Formate Neno: I gin ma ki lwongo ni calcium formate ma tye ki alkali manok, med potassium permanganate ma okato. Lyeto me neno ni jami ma ki lwongo ni oxidation reaction ni mede anyim. Potassium permanganate ma okato ni obi gonyo iodine ki potassium iodide i gin ma ki lwongo ni acidic solution, ma ki dong ki titrate ki sodium thiosulfate standard solution.
3.2 Kit me nongo Calcium Formate: Pimo pek pa calcium formate ma romo 0.4g (ma rwate ki 0.0002g), ket i 250ml volumetric flask, rubu i pii, dilute nio wa i lanyut, ki i yeny maber. Ket 25.00ml (onyo 10ml) me gin ma ki lwongo ni iodine flask, med 0.2g me anhydrous sodium carbonate, ki i yeng maber. Med 50.00ml (onyo 20ml) me potassium permanganate standard solution, lyeto i pii pi dakika 30, ki dong ngiic. Med 6ml me pii ma ki lwongo ni sulfuric acid ki 2g me potassium iodide, wek ocung i piny macol pi dakika 5. Titrate ki sodium thiosulfate ma ki lwongo ni standard solution; cok ki agiki, med 3ml me lanyut me jami ma ki lwongo ni starch (0.5%), ki med ki titrating nio ka kala ma bulu ni orweny woko. Tim gin ma ki lwongo ni blank test i kare acel.

Nong ber pa calcium formate ma pe ki twero loyo- medo tic pa jami ni ki dwoko piny wel cente! Itye ki miti me pwonyo mukene? Dii me penyo kombedi pi lagam ma ki yubu pi in!
