Define Procedure for Standardization of HCl for Saponification Number of Fats?
Precisely weigh 2.65 g of anhydrous sodium carbonate and transfer it to 100 ml volumetric flask. Make the volume to the mark with distilled water. This is a solution of 0.5 N sodium carbonate. Pipette 10 ml of this solution into a 100 ml conical flask and add a drop of methyl orange as an indicator. Titrate with standard HCI till the colour changes to red. Calculate the normality of the HCI.
