3.1 Calcium Formate Method Overview: Alkaline tlem calcium formate solution-ah chuan potassium permanganate standard solution tam lutuk dah tur a ni. Oxidation reaction chu a zawh thlengin a kal zel theih nan heat rawh. Potassium permanganate tam lutuk hian acidic solution-ah potassium iodide atanga iodine a chhuah tir ang a, chu chu sodium thiosulfate standard solution hmangin titrate a ni ang.
3.2 Calcium Formate Determination Steps:Calcium formate sample 0.4g vel (0.0002g thlenga dik) rit la, 250ml volumetric flask-ah dah la, tuiah hmin la, a mark thlengin dilute la, uluk takin vawt rawh. He solution 25.00ml (or 10ml) hi iodine flask-ah pipette la, anhydrous sodium carbonate 0.2g dah la, uluk takin vawt rawh.Potassium permanganate standard solution 50.00ml (or 20ml) dik takin dah la, water bath-ah minute 30 vel dah la, chutah chuan a lum ang. Sulfuric acid solution 6ml leh potassium iodide 2g dah la, thimah minute 5 vel dah la. Sodium thiosulfate standard solution hmangin titrate rawh; endpoint hnaihah starch indicator (0.5%) 3ml dah la, blue color a bo thlengin titrating chhunzawm rawh. Blank test chu a rualin tih tur a ni.
