What is the difference between ammonia and aqueous ammonia?
Ammonia contains one Nitrogen and three Hydrogen whereas Ammonium contains one Nitrogen and Four Hydrogen. Ammonia is a weak base and is un-ionized. Now talking of Ammonia, when it is dissolved in water, it becomes aqueous ammonia and when exposed to air, it becomes gas.
What is the difference between liquid nitrogen and anhydrous ammonia?
Anhydrous is very concentrated. It is 82\% nitrogen by weight, while urea is 46\%, and most liquid formulations are 32\%. Since other forms of nitrogen fertilizers are made from NH3, it’s unlikely they will ever be as inexpensive for the end user.
What is meant by aqueous ammonia?
n. (Elements & Compounds) a compound existing only in aqueous solution, formed when ammonia dissolves in water to form ammonium ions and hydroxide ions. Formula: NH4OH. Also called: aqueous ammonia.
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.
What is a property of anhydrous ammonia?
Anhydrous ammonia is a colorless non-flammable liquefied gas. Its vapor is lighter than air [(vapor density of 0.6) air = 1] and has the same pungent odor as household ammonia. Although ammonia vapor is lighter than air, the vapors from a leak may hug the ground appearing as a white cloud.
Why is aqueous ammonia not called ammonium hydroxide?
When Ammonia NH3 gas is dissolved in wader the Ammonium Hydroxide NH4OH is formed. therefore the Ammonium Hydroxide do not exist. Ammonia in solution does have some characteristics of a dissolved gas, and it is impossible to isolate a crystal of ammonium hydroxide.
Is anhydrous ammonia soluble in water?
Ammonia gas is very soluble in water. The relatively high solubility is attributed to the hydrogen bonding that takes place between the ammonia and water molecules.
Is anhydrous ammonia a liquid or gas?
Weight. Anhydrous ammonia is a colorless non-flammable liquefied gas. Its vapor is lighter than air [(vapor density of 0.6) air = 1] and has the same pungent odor as household ammonia. Although ammonia vapor is lighter than air, the vapors from a leak may hug the ground appearing as a white cloud.
What is the difference between liquor ammonia and liquid ammonia?
Both liquid and liquor ammonia are in the liquid state. However, the liquid ammonia has only ammonia molecules, but the liquor ammonia has both ammonia and water. The key difference between liquid ammonia and liquor ammonia is that the liquid ammonia contains NH3 molecules, while the liquor ammonia contains NH4OH.
What is liquid ammonia called?
At room temperature, ammonia is a colorless, highly irritating gas with a pungent, suffocating odor. Ammonia gas dissolves easily in water to form ammonium hydroxide, a caustic solution and weak base. Ammonia gas is easily compressed and forms a clear liquid under pressure.
What class is anhydrous ammonia?

Is aqueous ammonia explosive?
Nowadays, it is well recognized that ammonia can ignite and explode under certain conditions of con- tainment, within enclosures for instance, when its concentration in air is between 15 and 28\% v/v. These are the most accepted concentrations limits.
