Ammonium hydroxide solution 28%

Ammonium Hydroxide Solution 28%

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
