Assay by Titration: Weigh accurately 50mg of the sample and transfer it into 500 mL of beaker. Dissolve it in 5 mL of concentrated HCl, heat if necessary. Dilute this solution with 200 mL purified water and add Xylenol Orange indicator and sufficient Hexamine to produce violet-pink colour. Add a further 2 gm of Hexamine and titrate with 0.05M EDTA solution using magnetic stirrer until the colour changes to yellow. Determine the assay by using the following formula :
Assay  =  ( Burette Reading  x  Factor 3.2695  x  Actual Normality  x  100) / ( Weight of sample in mg  x  0.05)
