Monobasic Sodium Phosphate Monobasic
Mono Sodium Phosphate or Monosodium Phosphate (NaH2PO4, MSP), also known as anhydrous monobasic sodium phosphate or monosodium phosphate or sodium phosphate monobasic, is used as a laxative and, in combination with other sod. phos., as a pH buffer.
The pKa is 7.20. The sodium chloride equivalent value, or E-Value, is 0.49. It is soluble in 4.5 parts water. Monosodium phosphate is most commonly available as colorless crystals or a white powder. Sodium phosphate monobasic is insoluble in alcohol.

Action
and use
Excipient.
DEFINITION
Sodium
Dihydrogen Phosphate Monohydrate contains not less than 98.0% and not more than
100.5% of NaH2PO4, calculated with reference to the dried substance.
CHARACTERISTICS
Colourless
crystals or a white powder.
Very
soluble in water; very slightly soluble in ethanol (96%).
Dissolve
10.0 g in sufficient carbon dioxide-free water prepared from distilled
water to produce 100 ml (solution S).
IDENTIFICATION
A. Solution
S is faintly acid.
B. Solution
S yields the reactions characteristic of phosphates.
C. Solution
S neutralized with a 10% w/v solution of potassium hydroxide yields
reaction A characteristic of sodium salts.
D. Complies
with the test for Loss on drying.
TESTS
Acidity
pH of a
mixture of 5 ml of solution S and 5 ml of carbon dioxide-free water , 4.2
to 4.5.
Clarity
and colour of solution
Solution S
is clear and colourless.
Arsenic
0.5 g
complies with the limit test for arsenic - 2 ppm.
Heavy metals
12 ml of
solution S complies with limit test A for heavy metals. Use lead
standard solution (1 ppm Pb) to prepare the standard (10 ppm).
Iron
10 ml of
solution S complies with the limit test for - iron 10 ppm.
Chloride
Dilute 2.5
ml of solution S to 15 ml with water. The resulting solution complies
with the limit test for chlorides - 200 ppm.
Sulphate
To 5 ml of
solution S add 0.5 ml of hydrochloric acid and dilute to 15 ml with distilled water. The resulting solution complies with the
limit test for
sulphate - 300 ppm.
Reducing
substances
To 5 ml of
solution S add 0.25 ml of 0.02M potassium permanganate and 5 ml of 1M sulphuric acid and heat in a water bath for 5 minutes. The solution retains
a slight red colour.
Loss on
drying
When dried
to constant weight at 130°, loses 11.5 to 14.5% of its weight. Use 0.5 g.

Monobasic Sodium Phosphate contains one or two molecules of water of hydration, or is anhydrous. It contains not less than 98.0 percent and not more than 103.0 percent of NaH2PO4, calculated on the anhydrous basis.
Identification— A solution (1 in 20) responds to the tests for
Sodium 191 and for Phosphate.
pH: between 4.1 and 4.5, in a solution containing the equivalent of 1.0 g of
NaH2PO4·H2O in 20 mL of water.
Water:
less than 2.0% (anhydrous form); between 10.0% and 15.0% (monohydrate);
between 18.0% and 26.5% (dihydrate).
Insoluble substances— Dissolve a portion equivalent to 10.0 g of NaH2PO4·H2O
in 100 mL of hot water, filter through a tarred filtering crucible, wash the
insoluble residue with hot water, and dry at 105 for 2 hours: the weight of the
residue so obtained does not exceed 20 mg (0.2%).
Chloride— A portion equivalent to 1.0 g of NaH2PO4·H2O shows no more
chloride than corresponds to 0.20 mL of 0.020 N hydrochloric acid (0.014%).
Sulfate—
A portion equivalent to 0.20 g of NaH2PO4·H2O shows no more sulfate than
corresponds to 0.30 mL of 0.020 N sulfuric acid (0.15%).
Aluminum, calcium, and related elements— A solution containing the
equivalent of 1.0 g of NaH2PO4·H2O in 10 mL of water does not become turbid when
rendered slightly alkaline to litmus paper with 6 N ammonium hydroxide.
Arsenic—the
limit is 8 ppm.
Heavy
metals—the limit is 0.002%.
