ASSAY
Procedure
Sample: 5.5 g of Tribasic Sodium Phosphate, on the anhydrous basis
Blank: 100.0 mL of 1 N hydrochloric acid, accurately measured
Titrimetric system
Mode: Residual titration
Titrant: 1 N sodium hydroxide
Endpoint detection: Potentiometric
Analysis: Transfer the Blank to a 400-mL beaker and titrate with the Titrant to the endpoint at a pH of 7.0. Record as the volume consumed and designate as A. Transfer the Sample to a 400-mL beaker, add 100.0 mL of 1 N hydrochloric acid, and stir until dissolved. Pass a stream of carbon dioxide-free air, in fine bubbles, through the solution for 30 min to expel carbon dioxide, covering the beaker loosely to prevent any loss by spraying. Wash the cover and sides of the beaker with a few mL of water.
Titrate the excess acid potentiometrically with the Titrant to the inflection point at a pH of 4. Record the burette reading and designate as B. Protect the solution from carbon dioxide absorbed from the air and continue the titration with 1 N sodium hydroxide VS to the inflection point at a pH of 8.8. Record the burette reading, and designate as C.
Calculate the amount of Titrant consumed by the Sample to the first inflection point, correcting for the Blank (V1 = A - B) and the amount of Titrant consumed by the Sample between the two inflection points (V 2 = C - B). If ;V 1 is equal to or greater than 2V 2, calculate the amount of Na3PO4 in the portion of Sample taken:
D = V 2 x N x F
V 2 = volume of Titrant consumed between the two inflection points (mL)
N = actual normality of the Titrant (mEq/mL)
F = equivalency factor, 163.9 mg/mEq
If V 1 is less than 2V 2, calculate the amount of Na3PO4 in the portion of Sample taken:
D = (V 1 - V 2) x N x F
V 1 = volume of the Titrant consumed to the first inflection point, correcting for the Blank (mL)
N = actual normality of the Titrant (mEq/mL)
F = equivalency factor, 163.9 mg/mEq
Calculate the percentage of Na3PO4 on the ignited basis in the portion of Tribasic Sodium Phosphate taken:
Result = [10/(100 - L)] x (D/W)
L = percentage calculated in the test for Loss on Ignition.
D = amount of Na3PO4 found (mg)
W = weight of the Sample (g)
Acceptance criteria: NLT 97.0% of Na3PO4 on the ignited basis. Na3PO4-12H2O (dodecahydrate) contains NLT 92.0% of Na3PO4 on the ignited basis.
Sample: 2 g
Analysis: Dry the Sample at 110C for 5 h, and then ignite at 800C for 30 min.
Acceptance criteria: The anhydrous form loses NMT 2.0% of its weight, the monohydrate loses 8.0% to 11.0% of its weight, and the dodecahydrate loses 45.0% to 57.0% of its weight.
Arsenic: To pass the test.
Acceptance criteria: NMT 3 ppm
Insoluble Substances:
Sample solution: Dissolve a portion equivalent to 10.0 g of anhydrous tribasic sodium phosphate in 100 mL of hot water.
Analysis: Filter the Sample solution through a tared filtering crucible. [Note: Do not use glass.] Wash the insoluble residue with hot water, and dry at 105C for 2 h.
Acceptance criteria: The weight of the residue so obtained does not exceed 20 mg (0.2%).
Packaging and Storage: Preserve in tight containers. No storage requirements specified.
