Reactions. - When gradually heated, the salt melts at 165° to 168° C. (329° to 331° F.), and at about 185° C. (365° F.) it is decomposed into nitrous oxide gas and water, leaving no residue. The aqueous solution of the salt, when heated with potassa, evolves vapour of ammonia. On heating the salt with sulphuric acid, it emits nitrous vapours.
Use. - It is only used for the preparation of nitrous oxide.
