Preparation and Standardization of 0.05 M Barium Chloride
Preparation: Weigh 12.2 gm of barium chloride and transfer in 1000ml volumetric flask dissolve and dilute upto mark with purified water shake well.
Standardization : To 10.0 ml of the solution add 60 ml of water, 3 ml of strong ammonia solution and 0.5 to 1 mg of metalphthalein as
indicator and titrate with 0.05 M disodium edetate. As the solution begins to decolorise, add 50 ml of ethanol (95 per cent) and titrate until the bluish violet colour is discharged.
1 ml of 0.05 Mdisodium edetate is equivalent to 0.012215 g of Barium Chloride
