Ammonium carbonate 30%

Ammonium carbonate, particularly in a form described as "30% powder," warrants a detailed description due to its varied uses and chemical properties. Here's a breakdown:

Chemical Composition and Properties:

• Formula: (NH₄)₂CO₃
• Description:
  • Ammonium carbonate is an inorganic salt. It can exist in various hydrated forms, and it readily decomposes, releasing ammonia gas (NH₃), carbon dioxide (CO₂), and water (H₂O).
  • The "30%" designation typically refers to the approximate ammonia (NH₃) content. Therefore, it is important to note that the material is not 30% pure ammonium carbonate. Instead it is indicating the amount of available ammonia.
  • It's known for its characteristic strong ammonia odor.
  • It is soluble in water.
  • It is moisture sensitive.
• Instability:
  • A key characteristic of ammonium carbonate is its instability. It readily decomposes at room temperature, especially when exposed to air. This decomposition is accelerated by heat.

Applications:

• Leavening Agent:
  • Historically, and still in some applications, ammonium carbonate is used as a leavening agent in baking, particularly for flat cookies and biscuits. The decomposition releases carbon dioxide, which causes the dough to rise.
• Pharmaceuticals:
  • It has been used in certain pharmaceutical preparations, including some cough syrups and smelling salts.
• Laboratory Reagent:
  • In laboratory settings, it may be used in various analytical procedures. For example, it can be used in some forms of chemical analysis, and as a PH control agent.
• Other Uses:
  • It can also be used in the production of other ammonium salts, and in certain industrial processes.  

Safety Considerations:

• Irritant:
  • Ammonium carbonate can irritate the skin, eyes, and respiratory system.
• Handling:
  • It should be handled with care, preferably in a well-ventilated area, and appropriate personal protective equipment should be used.
• Storage:
  • It should be stored in tightly closed containers to prevent decomposition and exposure to moisture.

Key Points:

• The "30%" designation refers to approximate ammonia content.
• It is unstable and readily decomposes.
• It has varied uses, from baking to laboratory applications.
