Product description
- To determine nitrogen in a medicinal product, a 0.8880 g sample was treated with concentrated sulfuric acid. In this case, nitrogen was converted into ammonium hydrosulfate. The resulting solution was treated with alkali and the released ammonia was distilled into a solution containing 20 ml of HCl with THCl/NaOH = 0.0030 g/ml, and the excess acid was titrated with 5.5 ml of 0.1962 M NaOH solution. Calculate the mass fraction of nitrogen in the product.
