This standard BS 4651-6:1988 Ammonia solution is classified in these ICS categories:

• 71.060.40 Bases

This Part of BS 4651 describes two methods for the determination of the chloride content of ammonia solution for industrial use.

The methods are applicable to solutions containing 25.0 % to 35.0 % (m/m) of ammonia.

Method 1 is a colorimetric method applicable to products having a chloride content of not more than 150 mg/kg.

Method 2 is a potentiometric method applicable to products having a chloride content of greater than 150 mg/kg.

NOTE The publications referred to in this standard are listed on the inside back cover.

Applicable to ammonia solutions of concentrations within the range 25% to 35%, by mass. Two methods are described. The colorimetric method applies to products with chloride contents of not more than 150 mg/kg and the potentiometric method applies otherwise.
