Ammonia Solution 25% Pure Pack: 500mL, D Lab

Ammonia solution, often referred to as ammonia water, is a solution of ammonia (NH₃) dissolved in water.

Composition and Concentration of Ammonia Solution

• Ammonia solution is an aqueous solution of ammonia gas. Ammonia (NH3) is a compound composed of nitrogen and hydrogen atoms. Being highly soluble, this gas readily dissolves in water to produce ammonium hydroxide (NH₄OH). The resulting solution is commonly referred to as ammonia solution or ammonia water.
• The concentration can be calculated using the molecular weight and density. The density of the product is 0.9 g/mL, at 25%, so the molarity = Density x w/w% x 1000 / Mw = 0.9 g/mL x 25% x 1000 / 35.05 g/mol = 6.42 mol/L.

Uses of Ammonia Solution 25%

• Used in the production of plastics, textiles, and fertilizers
• In household and industrial-strength cleaning solutions 
• For purifying water supplies
• In laboratories, ammonia solution is used as a reagent in various chemical reactions.

Safety Precautions

• Ventilation: Always use ammonia in a well-ventilated area, as the fumes can be irritating to the respiratory system.
• Wear protective equipment: Wear chemical-resistant gloves, goggles, and a mask to protect your skin, eyes, and face
• Store ammonia separately: Store ammonia in separate spaces to reduce the risk of leaks.
• Monitor ammonia gas: Regularly monitor ammonia gas in the air to identify sources of emissions and reduce them. 

Ammonia solution is a versatile chemical with a wide range of applications. However, due to its potential hazards, it should be handled with care, following all safety guidelines.
