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.
