The grades, or strength of Ammonium Hydroxide usually available commercially are 26° and 21° Baumé. However, Tanner Industries, Inc. can produce any strength to meet our customers requirements. The Baumé reading refers to a specific gravity scale. A 26° Baumé solution is equivalent to 29.4% and 21° Baumé solution is equivalent to 19.68%, both by weight of ammonia dissolved in water. Since the Baumé reading varies with temperature, the reading is standardized at 60°F. The density of the material compared to water is 0.8974.
Aqua ammonia is corrosive to copper, copper 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.
An aqua ammonia solution has a vapor pressure which varies with temperatures. At ambient temperatures, the vapor pressure of 26° Baumé material just about equals atmospheric pressure. Aqua ammonia should be stored in a closed container and kept cool, otherwise, the ammonia gas will come out of solution and the material strength will be reduced.

Safety & Health
- Hazardous Properties
Ammonia, as a gas or in aqueous solution is an irritant and corrosive to the skin, eyes, respiratory tract and mucous membranes. It may cause severe burns, eye or lung injuries. Skin and respiratory related diseases are aggravated by exposure.
Ammonia vapor, when mixed with air, may be flammable within certain limits (15% to 28% gaseous ammonia by volume). Such concentrations are seldom encountered in practical handling; however, extreme caution should be exercised when welding on or near tanks containing or which formerly contained aqua ammonia. Aqua ammonia tanks, lines and equipment should be thoroughly purged of both aqua ammonia and ammonia vapors. The common metals are not affected by dry ammonia. Moist ammonia will not corrode iron or steel but will react rapidly with copper, brass, zinc and many alloys, especially those containing copper. Only steel or ductile iron should be used for ammonia containers, valves, fittings and piping.
Storage & Handling
- Storage of Ammonia
The vapor pressure of aqua ammonia is about equal to the atmospheric pressure, it must be stored in closed containers. The storage area should be dry and cool. If housed in a closed building, ventilation should be provided; either natural or mechanical. Avoid pocketing of ammonia vapor under floors, roofs or similar structures. Remember, ammonia vapor will burn when mixed in air at concentrations between 15% to 28%. Sparks or ignition sources must be excluded wherever concentrations in this range could exist.
