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
