Ammonium hydrogen is always in aqueous solution. The solution emits a pungent sulfur dioxide odor.
Aqueous solution of ammonium hydrogen produces ammonium salt (release ammonia when heated in the presence of sodium hydroxide) and sulfur dioxide (filter paper soaked in potassium iodate, starch turns blue).
Quantified according to the provisions of the appendix, the proportion of ammonium hydrogen ash should not be greater than 0.2/100.
Dilute the test solution prepared according to paragraph 7.2 to a tenth concentration and place 10 ml of this diluted solution (0.10 g ammonium hydrogen) in the steam distillation apparatus (see attachment). Add 10 mL of 30 pp 100 NaOH (R) and distill 100 mL. Distilled ammonia was quantified using 0.1 M hydrochloric acid. Let n be the number of milliliters used:

100 grams of ammonium hydrogen contains 1.7 nanograms of ammonia (NH3). The ammonia content should be greater than 16.5 pp 100 (m/m).
In a 200 mL Erlenmeyer flask, place 50 mL of cold water, then add 5 mL of freshly prepared ammonium hydrogen solution. Titrate with 0.05 M iodine in the presence of starch. Let n be the volume of iodine used.
Ammonium hydrogen solution should be stored in an airtight container away from sources of heat and cold.
In cooling baths, fire extinguishing compounds, baking powder formulations and in the manufacture of ceramics and pigments. Also used in composting to speed up decomposition. Ammonium bicarbonate is used as a reagent in the chemical industry. It is an active ingredient used in the manufacture of fire extinguishers, medicines, dyes, pigments and fertilizers. It finds application in the plastics, ceramics, leather and rubber industries. It is also used in cooling baths, limescale and plaster removers, leavening agents for baked goods and degreasers for textiles. Additionally, it acts as a buffer for purification of chemicals. Among other things, it is also involved in the gel digestion of proteins by trypsin and the mass spectrometry analysis of proteins.
