Is ammonia a gas or liquid?
gas
At room temperature, ammonia is a colorless, highly irritating gas with a pungent, suffocating odor. In pure form, it is known as anhydrous ammonia and is hygroscopic (readily absorbs moisture).
What phase is ammonia?
At standard conditions, ammonia is a gas. However, at low temperature and/or high pressures the gas becomes a liquid, and at more extreme conditions, a solid. The ammonia phase diagram shows the phase behavior with changes in temperature and pressure.
Can ammonia be a solid?
Ammonia and ammonium compounds come in liquid, gas, and solid forms. Pure ammonia is a gas, but if you’re working with cold ammonia, it will be in liquid form.
What state is ammonia at STP?
Ammonia is a gas at standard conditions. However, at low temperature and/or high pressures the gas becomes a liquid.
What type of gas is ammonia?
ammonia (NH3), colourless, pungent gas composed of nitrogen and hydrogen. It is the simplest stable compound of these elements and serves as a starting material for the production of many commercially important nitrogen compounds.
Is ammonia a basic gas?
Ammonia is moderately basic; a 1.0 M aqueous solution has a pH of 11.6, and if a strong acid is added to such a solution until the solution is neutral (pH = 7), 99.4% of the ammonia molecules are protonated.
Is ammonia polar or nonpolar?
polar
Ammonia is polar, the N is the negative end, and the middle of the H’s is the positive end.
What is triple point of ammonia?

Is ammonia a solid or liquid?
Ammonia is a colourless gas with a characteristically pungent smell. It is lighter than air, its density being 0.589 times that of air. It is easily liquefied due to the strong hydrogen bonding between molecules; the liquid boils at −33.1 °C (−27.58 °F), and freezes to white crystals at −77.7 °C (−107.86 °F).
Is ammonia an aqueous?
Ammonium hydroxide appears as a colorless aqueous solution. Concentration of ammonia ranges up to approximately 30%.
What is ammonia short answer?
ammonia (NH3), colourless, pungent gas composed of nitrogen and hydrogen. It is the simplest stable compound of these elements and serves as a starting material for the production of many commercially important nitrogen compounds. ammonia.
Why is ammonia called ammonia?
Ammonia takes it name from the worshippers of the Egyptian god Amun – the Ammonians, because they used ammonium chloride (NH4Cl) in their rites. Ammonium chloride (also known as sal volatile) occurs naturally in cracks near volcanoes, and when it is warmed it decomposes into the pungent ammonia.
