Ammonium bicarbonate is a white compound with the chemical formula NH4HCO3. It is in the form of granular, plate-like or columnar crystals and has an ammonia odor. Ammonium bicarbonate is a carbonate, so it must not be placed together with acid, because the acid will react with the ammonium bicarbonate to produce carbon dioxide, which will cause the ammonium bicarbonate to deteriorate. However, in rural areas, ammonium bicarbonate can also be used to react with acid. The ammonium bicarbonate is placed in a vegetable greenhouse, the greenhouse is sealed, the ammonium bicarbonate is placed at a high place, and dilute hydrochloric acid is added. At this time, ammonium bicarbonate will react with hydrochloric acid to produce ammonium chloride, water and carbon dioxide. Carbon dioxide can promote plant photosynthesis and increase vegetable yields, and the ammonium chloride produced can also be used as fertilizer again.
1. Used as nitrogen fertilizer, it is suitable for various soils and can simultaneously provide ammonium nitrogen and carbon dioxide required for crop growth, but it has low nitrogen content and is easy to agglomerate;
2. Used as analytical reagent, also used for synthesizing ammonium salt and fabric degreasing;
3. It can promote crop growth and photosynthesis, encourage seedlings to grow leaves, and can be used as top dressing, directly applied as base fertilizer, and used as food expansion agent;
4. Used as a high-grade fermentation agent for food. Combined with sodium bicarbonate, it can be used as a raw material for leavening agents in bread, biscuits, pancakes, etc., and also as a raw material for foaming powdered juice. It is also used for blanching green vegetables, bamboo shoots, etc., as well as medicine and reagents;
5. Used as buffer; aeration agent.
6. Ammonium bicarbonate is widely used in the plastic and rubber industry, pottery making, chrome tanning and synthetic catalysts.
7. Ammonium bicarbonate has the advantages of being quick-acting, cheap, economical, not hardening the soil, suitable for various crops and soils, and can be used as both base fertilizer and top dressing. It is welcomed by farmers.
