ammonium chloride as acidifiers

Ammonium chloride (NH₄Cl) as an acidifier is commonly used to acidify solutions or environments, especially in medical, agricultural, and industrial applications.

🔬 How Ammonium Chloride Works as an Acidifier

  • Ammonium chloride dissociates in water:



  • The ammonium ion (NH₄⁺) is a weak acid and can release H⁺ ions through this equilibrium: 
  • This release of H⁺ lowers the pH, thus acidifying the solution.

⚙️ Common Uses of Ammonium Chloride as an Acidifier

  1. Medical Use
    • Treat metabolic alkalosis by acidifying blood plasma.
    • Used in some cough medicines for its expectorant and acidifying properties.
  2. Agriculture
    • Added to animal feed to acidify urine, reducing the risk of urinary stones in livestock.
    • Helps maintain soil pH in some conditions.
  3. Industrial Applications
    • In metal finishing and plating baths to control pH.
    • In electrolytes for batteries.

🔎 Advantages of Using Ammonium Chloride

  • Water-soluble and easy to handle
  • Mild acidifying effect compared to strong acids
  • Provides ammonium ions beneficial in some biological contexts

⚠️ Notes and Safety

  • Overuse can lead to acidosis or irritation.
  • Should be used carefully following recommended dosages.
  • Handle with gloves and avoid inhalation of dust.
