Is 19% aqueous ammonia flammable?
Ammonium hydroxide is very volatile and may release ammonia as a gas. Ammonia vapor, in concentrations of 16-25% volume by weight in air, is flammable, toxic by inhalation and corrosive.
What is aqueous ammonia used for?
Ammonium hydroxide is used as a cleaning agent and sanitizer in many household and industrial cleaners. Ammonium hydroxide is also used in the manufacture of products such as fertilizer, plastic, rayon and rubber. Aqueous ammonia is corrosive to aluminum alloys, copper, copper alloys, and galvanized surfaces.
Does aqueous ammonia evaporate?
Water absorbs ammonia to form ammonium hydroxide and has a high pH (alkaline). Contain pooled amounts in a safe location so that the ammonia solution can evaporate or otherwise be mitigated. Ammonia will follow the wind direction and track along low valleys until it dissipates.
What is the density of aqueous ammonia?
880 kg/m³
Ammonia solution/Density
Is aqua ammonia corrosive?
Hazard Description Ammonia is an irritant and corrosive to the skin, eyes, respiratory tract and mucous membranes. May cause severe chemical burns to the eyes, lungs and skin. Skin and respiratory related diseases could be aggravated by exposure.
Why emergency responders should not apply water directly to the release of aqueous ammonia?
If the water in the tank is not changed once saturation occurs, little additional liquid or vapor can be absorbed. This may result in over-pressurization of the tank, which may result in an explosive tank failure if the tank is not vented.
Is aqueous ammonia ammonium hydroxide?
ammonium hydroxide, also called ammonia solution, ammonia water, aqueous ammonia, or aqua ammonia, solution of ammonia gas in water, a common commercial form of ammonia. It is a colourless liquid with a strong characteristic odour.
What is aqua ammonia as a fertilizer?
Aqua ammonia is a solution of ammonia gas and water and has a sharp, irritating odor. Aqua ammonia is one of CALAMCO’s key fertilizer products. It is used as a source of nitrogen, and also has an ingredient in the manufacture of some specialty fertilizers.
Is aqueous ammonia safe?
Hazard statements : Harmful if inhaled. Causes severe skin burns and eye damage. May cause respiratory irritation. only outdoors or in a well-ventilated area.
Is aqueous ammonia harmful?
Ammonia is an irritant and corrosive to the skin, eyes, respiratory tract and mucous membranes. May cause severe chemical burns to the eyes, lungs and skin. Skin and respiratory related diseases could be aggravated by exposure.
What are the physical properties of aqua ammonia?
Physical Properties Aqua ammonia is a clear, colorless liquid having a strong pungent ammonia odor. Specific Gravity The specific gravity of aqua ammonia is customarily expressed as its density at 60°F compared to the density of water at 60°F.
What is the freezing point of aqua ammonia?
Aqua ammonia is corrosive to copper, cooper alloys, aluminum alloys and galvanized surfaces. Aqua ammonia is an excellent acid neutralizer. Its pH varies with concentration. Typical values are 11.7 at 1%, 12.2 at 5%, 12.4 at 10% and 13.5 at 30%. The freezing point of a 26° Baumé solution is about -110°F.
Why is ammonium hydroxide a weak base in water?
Chemical Properties pH Aqua ammonia (ammonium hydroxide) is classified as a weak base. It ionizes much less completely in water than does a strong base such as sodium hydroxide. This is reflected in the pH’s normally encountered with solutions of ammonia.
