Zinc Oxide USP23

 

 

Test Item Specification
Appearance 
 

 
White powder
Purity 99.0%-100.5%
Identification A:When stongly heated,it assumes a yellow color  that disappears on cooling 
B:Asolution of it in a slight excess of 3N
hydrochloric acid responds to the tests for 
Zinc<191>
Alkalinity Mix 1.0g with 10ml of hot water,add 2 drops of
phenolphthalein TS,and filter;if a red color
is produced.not more than 0.30ml of 0.10 N 
  hydrochloric acid is required to discharge it 
Loss on ignition: not more than 1.0%
As not more than 6ppm
color of solution Mix 2.0g with 10ml of water,add 30ml of 2N
sulfuric acid,and heat on a steam bath,with
contant stirring;no effervescence occoursand the resulting solution is clear and colorless
Lead(Pb) Add 2g to 20ml of water,stir well,add 5ml of
glacial acetic acid,and warm on a steam bath 
  until solution is effected,the addition of 5 
drops of potassium chromate TS produces no trubidity or precipitate
Iron and other 
heavy metals Cooled 5ml portions of the solution obtained
  in the test for Carbonate and color of solution
yield white precipitates with potassium
ferrocyanide TS and with sodium sulfide TS
Mesh size (through 325 mesh )    99% min
