Product description

36. For the photometric determination of molybdenum in a mineral with dithiol, a standard solution of ammonium molybdate was prepared by dissolving 0.1000 g of it in 500 cm. Aliquot parts of the solution after treatment with a reagent and bringing the volume to 50 cm were photo-photometric. The measurement data is as follows:
The volume of aliquots, VA, ml 0.50 1.00 1.50 2.00
Opt. density, And 0,231 0,465 0,690 0,940
Determine the mass fraction (%) of MoO3 in the mineral, if a 0.2400 g sample was taken for analysis, dissolved in 100.00 ml. The same reagent was added to an aliquot of 10.00 ml, the volume was increased to 50.00 ml. the optical density of such a solution is 0.510.
