 hydrochloric acid responds to the tests for
 Zinc<191>
AlkalinityMix 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 ignitionnot more than 1.0%
Asnot more than 6ppm
Carbonate and color of solutionMix 2.0g with 10ml of water,add 30ml of 2N
