Ammonium bicarbonate is a white, crystalline compound with the chemical formula NH4HCO3. It is a type of inorganic salt that is commonly used in the food industry as a leavening agent for baking, as well as in the production of ceramics, dyes, and other chemicals. When heated, ammonium bicarbonate decomposes into ammonia, carbon dioxide, and water vapor, which causes dough to rise and become light and fluffy. It is also known as hartshorn or baker’s ammonia.
Description
Ammonium bicarbonate Uses
- Food industry: Ammonium bicarbonate is commonly used as a leavening agent in baked goods such as cookies, crackers, and biscuits. It produces carbon dioxide when heated, which causes the dough to rise and gives the baked goods a light and fluffy texture.
- Agriculture: Ammonium bicarbonate is used as a fertilizer in agriculture because it provides nitrogen to plants, which is an essential nutrient for their growth.
- Pharmaceutical industry: Ammonium bicarbonate is used as an ingredient in some medications, particularly in effervescent tablets, to provide a fizzy sensation when dissolved in water.
- Chemical industry: Ammonium bicarbonate is used as a source of ammonia and carbon dioxide in the production of other chemicals such as dyes, pigments, and plastics.
- Cleaning industry: Ammonium bicarbonate is sometimes used as a cleaning agent for metals, such as brass and copper, due to its ability to remove tarnish and corrosion.
Other industries: Ammonium bicarbonate can also be used in the production of ceramics, as a blowing agent in the rubber industry, and in fire extinguishers as a non-toxic, non-corrosive, and non-conductive extinguishing agent.

Acetaldehyde
Acetaldehyde
Acetaldehyde is a simple organic compound with the chemical formula CH3CHO. It is a colorless liquid with a pungent, fruity odor. Here are some key points about acetaldehyde:
- Chemical Structure: Acetaldehyde consists of two carbon atoms, one oxygen atom, and four hydrogen atoms. Its structure is CH3CHO, where the carbon atom in the middle is doubly bonded to an oxygen atom and singly bonded to a hydrogen atom and a methyl group (CH3).
- Occurrence: Acetaldehyde can be found naturally in various ripe fruits, coffee, and heated milk. It is also produced by the oxidation of ethanol (alcohol) by enzymes in the liver and other tissues in humans, making it an intermediate product in alcohol metabolism.
