Why is barium chloride and alcohol used in the limit test for sulphates?
barium chloride reacts with a sulphate to produce barium sulphate which can be seen as a white precipitate and therefor identified.
Why hcl used in the limit test of sulphates?
to remove the impurities of sulphate
What the sulphate limit in soil after then use sulphate resistant cement?
the limit concentration of sulphate is 1000 ppm after that "sulphate resistant cement" should be used
Why is Barium Sulphate used in the limit test for sulphates?
Barium sulfate is very sparingly soluble. Any addition of it to a solution containing sulfate or barium will almost immediately cause a precipitate to form.

Why do we saturate ammonium sulphate in rothera's test?
Rothera's test is used to detect the presence of ketone bodies in a solution (eg urine). it utilizes sodium nitroprusside, liquid ammonia and ammonium sulphate. ammonium sulphate is used to concentrate the ketone bodies to the center of the solution. the other 2 constituents react with ketone bodies to form pink coloured polymerized compound. Rothera's test is used to detect the presence of ketone bodies in a solution (eg urine). it utilizes sodium nitroprusside, liquid ammonia and ammonium sulphate. ammonium sulphate is used to concentrate the ketone bodies to the center of the solution. the other 2 constituents react with ketone bodies to form pink coloured polymerized compound. Ammonium ion is used to precipitate the proteins that may be present.. Because proteins can give a positive result to Rothera's test as well..
