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 (about 100C)
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.
HEAVY METALS: Dissolve 6.0 g in about 20 mL
of water, and dilute with water to 30 mL. Use 25 mL to prepare the
sample solution, and use the remaining 5.0 mL to prepare the control
solution. Adjust the pH with ammonium acetate solution.
IRON.
Use 2.0 g.
CALCIUM,
MAGNESIUM, POTASSIUM, SODIUM, AND ZINC: (By flame AAS 39).
To pass the test.
