DESCRIPTION
Ammonium Chloride occurs as colorless crystals or as a white, fine or coarse, crystalline powder. It is somewhat hygroscopic. One gram dissolves in 2.6 mL of water at 25°, in 1.4 mL of boiling water, in about 100 mL of alcohol, and in about 8 mL of glycerin. The pH of a 1:20 solution is between 4.5 and 6.0.

DEFINITION
Content or Assay:99.0 per cent to 100.5 per cent (On dried substance basis).

CHARACTERS
Appearance:White or almost white, crystalline powder or colorless crystals.
Solubility: Freely soluble in water.

IDENTIFICATION
A. It gives the reactions of chlorides.
B. 10 ml of solution gives the reaction of ammonium salts.

TESTS
Solution S: A 10% solution: Appearance of solution: Solution is clear and colorless.
Acidity or alkalinity: To 10 ml of solution S add 0.05 ml of methyl red solution. Not more than 0.5 ml of 0.01 M hydrochloric acid or 0.01 M sodium hydroxide is required to change the color of the indicator.
Bromides and iodides: To 10 ml of solution S add 0.1 ml of dilute hydrochloric acid R and 0.05 ml of chloramine solution. After 1 min, add 2 ml of chloroform R and shake vigorously. The chloroform layer remains colorless.
Sulphates: Maximum 150 ppm.
Calcium: Maximum 200 ppm.
Iron: Maximum 20 ppm.
Heavy metals: Maximum 10 ppm.
Loss on drying: Maximum 1.0 per cent, determined on 1.00 g by drying in an oven at 105 °C for 2 h.
Sulphated ash: Maximum 0.1 per cent, determined on 2.0 g.

Assay— Ammonium Chloride contains not less than 99.5 percent and not more than 100.5 percent of NH4Cl, calculated on the dried basis.
Packaging and storage— Preserve in tight containers.
Identification— A solution (1 in 10) responds to the tests for Ammonium and for Chloride
pH: between 4.6 and 6.0, in a solution (1 in 20).
Loss on drying— Dry it over silica gel for 4 hours: it loses not more than 0.5% of its weight.
Residue on ignition— Add 1 mL of sulfuric acid to about 2 g, accurately weighed, and heat the mixture gently until volatilization is complete: the residue is white, and when ignited, not more than 0.1% of nonvolatile substance remains.
Limit of thiocyanate— Acidify 10 mL of a solution (1 in 10) with hydrochloric acid, and add a few drops of ferric chloride TS: no orange-red color is produced.
Heavy metals: 0.001%.

A jackal woke up early in the morning and went in to the plains. He looked at his long shadow in the rising morning sun and said to himself, "I must have a camel for my meal today".

He kept moving around till noon and it was getting hot and the jackal was tired. He was also hungry and thirsty. He looked at his small shadow in the mid-day sun. He murmered, "I was only joking about the camel, a mouse will do".
