Determination of Residue on Evaporation in Anhydrous Ammonia

1 SCOPE AND FIELD OF APPLICATION
This method is suitable for the determination of the residue left after evaporation i.e., the non-volatile material in ammonia solution.

2 PRINCIPLE

A known weight of sample is evaporated to dryness in a platinum dish on a steam bath. The increase in mass of the dish is measured.

  • AMMONIA SOLUTION: Determination of Residue on Evaporation in Anhydrous Ammonia WARNING AND SAFETY PRECAUTIONS: AMMONIS SOLUTION: SPLASHES INT0 EYES CAN CAUSE SEVERE BURNS. AVOID INGESTION. PRESSURE MAY BUILD UP IN CLOSED CONTAINERS. 1 SCOPE AND FIELD OF APPLICATION This method is suitable for the determination of the residue left after evaporation i.e., the non-volatile material in ammonia solution. 2 PRINCIPLE A known weight of sample is evaporated to dryness in a platinum dish on a steam bath. The increase in mass of the dish is measured. 3 APPARATUS Normal laboratory apparatus and: 3.1 Platinum evaporation dish. 3.2 Muffle furnace capable of operating at 1000°C. 3.3 Steam bath.

  • 4 PROCEDURE Ignite a large platinum dish (3.1) in a Muffle furnace (3.2) at about 900°C for a few minutes, allow to cool thoroughly in a desiccator and weigh to the nearest 0.1 mg. Weigh approximately 200 g sample into the platinum dish and evaporate on a steam bath (3.3). Remove the dish from the steam bath and dry for 30 minutes in a suitable oven at 100 + 2°C. Cool thoroughly in a desiccator and reweigh to the nearest 0.1 mg; reserve for the Residue on Ignition test. 5.1 Expression of Results Let w g - increase in mass of platinum dish. 5.2 Precision Precision was not available at the time of issue.
