(1) Take a small amount of this product with the fire burning, that is, slow decomposition, but does not occur caramel smell.
(2) sample solution with 4.3% sodium hydroxide solution to neutral, plus 5% sulfuric acid solution heated to boiling mercury, plus 1 drop of 0.1m potassium permanganate solution, after shaking subsided purple and white precipitate.
(3) take the sample to neutral solution plus 7.5% of excess calcium chloride solution, no change in cold, boiled white granular precipitate is produced. Take this solution, part of the added 4.3% sodium hydroxide solution, insoluble precipitate; part by adding 24% hydrochloric acid, then dissolved.
(4) to neutral to take the sample solution plus excess 0.1mol / L silver nitrate solution, which produce a white precipitate. This precipitation in 40% nitric acid or ammonia solution to dissolve. Take this test tube placed in the solution of ammonia in the water bath heated to 60 ~ 70 °C, no significant silver wall mirror.
