Ammonium Hydroxide 25%
Ammonium Hydroxide 25% is an aqueous solution of ammonia, commonly utilized as a base in various industrial and laboratory applications.
Description
Ammonium Hydroxide 25%, also known as ammonia water or ammoniacal liquor, is an aqueous solution containing 25% by weight of ammonia (NH3) dissolved in water. The chemical formula is conventionally represented as NH4OH to signify the existence of ammonium ions (NH4+) and hydroxide ions (OH-) in solution, although ammonia itself does not form a stable hydroxide molecule. This solution is a colorless liquid characterized by its strong, pungent odor. Its alkalinity makes it a versatile chemical reagent and processing aid across numerous industries. The equilibrium between dissolved ammonia and ammonium hydroxide is dynamic and temperature-dependent, influencing its reactivity and volatility. Due to its corrosive nature, appropriate handling and storage protocols are paramount to ensure safety and maintain product integrity. This solution serves as a critical intermediate or end-product component in a wide array of manufacturing processes.
Applications
Ammonium Hydroxide 25% finds extensive use as a buffering agent and a titrant in chemical analysis. Industrially, it is a key component in the production of fertilizers, such as ammonium nitrate and urea, and in the synthesis of other nitrogen-containing compounds. It is also employed in the textile industry for scouring, dyeing, and finishing operations. In the rubber industry, it serves as a coagulant for latex. Furthermore, it is used as a cleaning agent in both domestic and industrial settings, particularly for degreasing and glass cleaning. Other applications include pH adjustment in wastewater treatment, extraction processes in mining, and as a stabilizer in some food products.
Storage & Handling
Store in a cool, well-ventilated area, away from incompatible materials and direct sunlight. Containers should be tightly sealed and made of compatible materials (e.g., polyethylene). Handle with appropriate personal protective equipment to prevent skin and eye contact, and inhalation of vapors.
