Molecular Weight: 65.39
Zinc Granules and Zinc Dust or Zinc Powder Precisely Sized
Specifications of Zinc Dust or Zinc Powder:
Description: Dark Grey, Fine, Metallic Powder or Granules as specified.
Metallic Zinc: 98.0 Min % by wt
Total Zinc (as Zn): 99.5 min % by wt
Lead (as Pb): 50 ppm Max
Iron (as Fe): 100 ppm max
Arsenic (as As): 5 ppm max
Specific Gravity: 7.1 gm/cc3
Particle size D(90): May be specified as -- Not more than 80 µm. We can also offer as per buyers requirement.
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)
