Module 2. Redox titration. Bromo- and Bromatometric titration. Nitritometry Variant 1 Mass of N 1. Solution of potassium bromate was prepared by dissolving the sample 0.0556 g of potassium bromate in 200.00 ml volumetric flask. Calculate the molar concentration Mass fracs of equivalent of the solution and titer of potassium bromate by arsenic (II1). 2. Calculate the mass of sodium nitrite you need to prepare 250.00 ml of 0.05 N solution of sodium nitrite. Calculate the titer by sulfanilic acid of the prepared solution.
