A test made by adding, drop by drop, a weak solution of ammonia to a solution of silver nitrate until the brown precipitate first produced is nearly dissolved, decanting the clear liquid, and adding it to the suspected liquid. If arsenic is present, a bright yellow precipitate of silver arsenite is produced, that must be collected and heated with a reducing agent so as to form a sublimate of metallic arsenic.
