Ammonium Hydroxide Solution 28%

Description:

Ammonium Hydroxide Solution 28%, also known as Aqueous Ammonia, is a solution of ammonia (NH₃) dissolved in water. The concentration of ammonia in this solution is approximately 28%, making it a strong alkaline solution. It is widely used in various chemical, industrial, and laboratory applications due to its high pH and reactivity with acids, metals, and other substances.


Specifications:

  • Chemical Formula: NH₄OH (ammonium hydroxide)

  • Concentration: Typically 28% ammonia by weight (often referred to as 28% ammonia solution)

  • Density: Approx. 0.90–0.91 g/mL at 20°C

  • pH: Around 11–12 (strongly alkaline)

  • Appearance: Colorless, clear liquid with a pungent odor

  • Boiling Point: 37.7°C (100°F) (Ammonia gas begins to escape at this temperature)

  • Solubility: Fully soluble in water; forms ammonia gas when exposed to air

  • Storage: Store in tightly sealed containers in a cool, well-ventilated area away from incompatible materials


Uses:

  • Chemical Synthesis:

    • Used in the production of various ammonium salts (e.g., ammonium nitrate, ammonium sulfate) and other chemicals

  • Laboratory Reagent:

    • Used as a base in various titrations, and as a reagent in analytical chemistry for reactions involving metal ions and acid-base neutralizations

  • Cleaning Agent:

    • Employed in industrial and household cleaning, especially for removing grease and stains from surfaces

  • Water Treatment:

    • Used to adjust pH in water treatment plants and for neutralizing acidic water in environmental applications

  • Textile and Paper Industries:

    • Used for the bleaching and cleaning of textiles and paper products

  • Agriculture:

    • In fertilizers and for neutralizing acidic soils

  • Pharmaceuticals and Food Processing:

    • Sometimes used in pharmaceutical formulations and food processing, but under controlled and limited circumstances
