Ammonia NH3 by Mind Map: Ammonia NH3

1. Important Characteristics

1.1. Ammonia, azne, nitrogen trihydride, or ammonium gas is a chemical compound whose molecule is made up of one nitrogen atom (N) and three hydrogen atoms (H) according to the formula NH3.

1.2. Another name for Ammonia is anhydrous ammonia which means absence of water.

1.3. The ammonia, at room temperature, is a very penetrating and nauseating odor colorless gas.

1.4. It occurs naturally by decomposition of organic matter and is also manufactured industrially. It is easily soluble and evaporates quickly.

1.5. It is characterized because it is a strong, corrosive base that reacts violently with acids, strong oxidants and halogens.

2. Uses and Beneficts

2.1. Once exposed to open air, liquid ammonia quickly turns into a gas.

2.2. It is an important source of nitrogen which is needed by plants and animals.

2.3. Ammonia can be used to purify water supplies and as a building block in the manufacture of many products.

2.4. Ammonia is applied directly into soil on farm fields, and is used to make fertilizers for farm crops, lawns, and plants.

2.5. Many household and industrial cleaners contain ammonia.

3. General Effects

3.1. Exposure to high levels of ammonia in the air can cause severe burns.

3.2. When ammonia is present in water at high enough levels, it is difficult for aquatic organisms to sufficiently excrete the toxicant.

3.3. Swallowing a cleaning product that contains ammonia can burn the mouth, throat, and stomach and cause severe abdominal pain

4. Effects in the enviroment

4.1. Ammonia is found throughout the environment in the air, soil,and water, and in plants and animals including humans.

4.2. It is a very important nutrient for its development, although the presence of high concentrations in surface waters, like any nutrient, can cause serious damage to water.

4.3. Cause damage to aquatic ecosystems, when an excess of nitrogen nutrients is produced that seeps into freshwater.

4.4. Ammonia in water is non-toxic to humans, but it is toxic to aquatic life. Exposure to them can have "consequences ranging from slight effects on the respiratory system to allergies or even premature mortality."
