Potassium Chloride USP Specifications
KCl 74.55
Assay— Potassium
Chloride contains not less than 99.0 percent and not more than 100.5 percent
of KCl, calculated on the dried basis.
Packaging and storage— Preserve in well-closed containers.
Labeling— Where
intended for use in hem dialysis, it is so labeled.
Identification— A
solution (1 in 20) responds to the tests for Potassium and for Chloride.
Acidity or alkalinity— To a solution of 5.0 g in 50 mL of carbon dioxide–free water add 3 drops
of phenolphthalein TS: no pink color is produced. Then add 0.30 mL of 0.020
N sodium hydroxide: a pink color is produced.
Loss on drying — Dry it at 105 for 2 hours: it loses not more than 1.0% of its
weight.
Iodide or bromide—
IODIDE—
Standard stock
solution— Transfer an accurately weighed quantity, about 41 mg, of
potassium iodide to a 25-mL volumetric flask. Dissolve in and dilute with
water to volume, and mix.
Standard solution— Dilute 1.0 mL of Standard stock solution
with water to 25 mL, and
mix. Dilute 2.0 mL of this solution with water to 8 mL, and proceed as
directed for Test solution beginning with “Add 1 mL each of
chloroform”.
Test solution— Dissolve 2 g in 8 mL of water. Add 1 mL each of
chloroform and diluted hydrochloric acid, then add 2 drops of a chloramine T
solution (0.1 in 100), and shake gently. The violet color of the chloroform
layer is not darker than that of a concomitantly prepared Standard
solution: the limit is 0.005%.
BROMIDE—
Standard solution— Transfer an accurately weighed quantity, about 32 mg, of sodium bromide to a
25-mL volumetric flask. Dissolve in and dilute with water to volume, and
mix. Dilute 2.0 mL of this solution with water to 8 mL, and proceed as
directed for Test solution beginning with “Add 1 mL each of
chloroform”.
Test solution— Dissolve 2 g in 8 mL of water. Add 1 mL each of
chloroform and diluted hydrochloric acid, then add 5 drops of a chloramine T
solution (1 in 100), and shake gently. The brown color of the chloroform
layer is not darker than that of a concomitantly prepared Standard
solution: the limit is 0.1%.
Aluminum— where it
is labeled as intended for use in hem dialysis— Proceed as directed using
2.0 g of Potassium Chloride to prepare the Test Preparation: the
limit is 1 µg per g.
Calcium and magnesium—
To 20 mL of a solution (1 in 100) add 2 mL each of 6 N ammonium
hydroxide, ammonium oxalate TS, and dibasic sodium phosphate TS: no
turbidity is produced within 5 minutes.
Sodium— A solution
(1 in 20), tested on a platinum wire, does not impart a pronounced yellow color to a non-luminous
flame.
Heavy metals— Dissolve 2.0 g in 25 mL of water: the limit is 0.001%.
Organic volatile
impurities: meets the requirements.

KCl 74.55
DEFINITION
Content
99.0 per cent to 100.5 per cent of KCl (dried substance).
CHARACTERS
Appearance
White or almost white, crystalline powder or colourless crystals.
Solubility
Freely soluble in water, practically insoluble in anhydrous ethanol.
IDENTIFICATION
It gives the reactions of chlorides.
Solution S gives the reactions of
potassium.
TESTS
Solution S
Dissolve 10.0 g in carbon dioxide-free water R
prepared from distilled water R and dilute to 100 ml with the same solvent.
Appearance of solution: Solution S is clear and colourless.
Acidity or alkalinity:
To 50 ml of solution S add 0.1 ml of bromothymol blue solution. Not
more than 0.5 ml of 0.01 M hydrochloric acid
or 0.01 M sodium hydroxide is required to change the colour of the
indicator.
Bromides: Maximum 0.1 per cent.
Iodides: Moisten 5 g by the drop wise addition of a freshly prepared mixture of 0.15
ml of sodium nitrite solution, 2 ml of 0.5 M sulphuric acid ,
25 ml of iodide-free starch solution and 25 ml of water. After
5 min, examine in daylight. The substance shows no blue colour.
Sulphates: Maximum 300 ppm.
Aluminium: Maximum 1.0 ppm, if intended for use in the manufacture of hem dialysis
solutions.
Barium: To 5 ml of solution S add 5 ml of
distilled water and 1 ml of dilute sulphuric acid. After 15 min, any opalescence in the solution is
not more intense than that in a mixture of 5 ml of solution S and 6 ml of distilled water.
Iron: Maximum 20 ppm.
Magnesium and
alkaline-earth metals: Maximum 200 ppm, calculated as Ca.Sodium: Maximum 0.10 per cent, if intended for use in the manufacture of parenteral
preparations or hem dialysis solutions.Heavy metals:
Maximum 10 ppm.
Loss on drying:
Maximum 1.0 per cent, determined on 1.000 g by drying in an oven at 105 C
for 3h.

KCl 74.55
Formula wt 74.55
DESCRIPTION: Potassium Chloride occurs as colorless, elongated, prismatic, or cubical
crystals, or as a white, granular powder. It is stable in air. Its solutions
are neutral to litmus. It may contain up to 1.0% (total) of suitable
food-grade ant-caking, free-flowing, or conditioning agents such as calcium
stearate or silicon dioxide, either singly or in combination. One gram
dissolves in 2.8 mL of water at 25°, and in about 2 mL of boiling water.
Potassium Chloride containing anti-caking, free-flowing, or conditioning
agents may produce cloudy solutions or dissolve incompletely. It is
insoluble in alcohol.
Function: Nutrient;
gelling agent; salt substitute; yeast food.
REQUIREMENTS:
Identification:
A 1:20 aqueous solution gives positive tests for Potassium and for Chloride.
Assay: Not less than
99.0% of KCl after drying; and not less than 98.0% of KCl after drying when
a sample contains added substance.
Acidity or Alkalinity: A sample containing no added substance passes test.
Heavy Metals (as
Pb): Not more than 5 mg/kg.
Iodide and/or Bromide: Passes test.
Loss on Drying: Not
more than 1.0%.
Sodium: Passes test.
