TESTS
ASSAY: (By complexometric titration of Mn). Weigh accurately 0.8 g, transfer to a 500-mL beaker, and dissolve in 200 mL of water. Add a few milligrams of ascorbic acid to prevent oxidation. From a burette, add about 30 mL of standard 0.1 M EDTA. Now add 10 mL of pH 10 ammoniacal buffer solution and about 50 mg of Eriochrome Black T indicator mixture. Continue the titration with EDTA to a clear blue color (and disappearance of the last trace of red). One milliliter of 0.1 M EDTA corresponds to 0.01979 g of MnCl2 . 4H2O.
% MnCl2 · 4H2O = (mL × M EDTA × 19.79) / Sample wt (g)
pH OF A 5% SOLUTION: The pH
should be 3.5-6.0 at 25C.
INSOLUBLE MATTER: Use 20 g
dissolved in 150 mL of water.
SULFATE: Dissolve 10 g in 100 mL of water, add
1 mL of hydrochloric acid, filter, and heat the filtrate to boiling.
Add 10 mL of barium chloride reagent solution, digest in a covered
beaker on a hot plate (
100
C)
for 2 h, and allow to stand overnight. If a precipitate is formed,
filter through a fine ash less paper, wash thoroughly, and ignite.
Correct for the weight obtained in a complete blank test.
IRON. Use 2.0 g.
CALCIUM, MAGNESIUM, POTASSIUM, SODIUM, AND ZINC: (By flame AAS 39).
Sample Stock Solution: Dissolve 5.0 g in water in a 100-mL volumetric flask, add 0.5 mL of hydrochloric acid, and dilute with water to the mark (1 mL = 0.05 g).
