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 |
