1.	It is not advisable to use sulphuric acid in place of acetic acid for acidification while testing sulphur by lead acetate test. Assign reason.
Answer» SOLUTION :Lead acetate will REACT with sulphuric acid to give white precipitate of lead SULPHATE. This will interfere with the detection of the TEST for sulphur. `underset("Lead acetate")((CH_(3)COO)_(2))Pb+H_(2)SO_(4) rarr underset("(White ppt.)")(PbSO_(4))+2 CH_(3)COOH` Acetic acid `(CH_(3)COOH)` will not interfere in the detection of sulphur.
