To determine chloride in nitric acid by nephelometric titration, 100 ml of the test HNO3 (p=1.47 g/cm3) was diluted to 250 ml with water. To prepare a suspension of AgCl, 25 ml of the prepared HNO3 solution, V (ml) 0.09815M AgNO3, 5 ml of gelatin solution and
V, ml AgNO3 2.00 4.00 6.00 8.00 10.00
Acaj 0.62 0.40 0.21 0.15 0.12
Construct a titration curve and determine the mass fraction (%) of the chloride ion in nitric acid.
