At what pressure does argon liquify?
48 atmospheres
Argon gas condenses to a colourless liquid at −185.8 °C (−302.4 °F) and to a crystalline solid at −189.4 °C (−308.9 °F). The gas cannot be liquefied by pressure above a temperature of −122.3 °C (−188.1 °F), and at this point a pressure of at least 48 atmospheres is required to make it liquefy.
Why argon has no reaction with acids?
The argon atom has 18 electrons and 18 protons. Its outer shell is full with eight electrons. Under standard conditions argon is an odorless and colorless gas. It is also an inert gas, meaning that it typically doesn’t react with other elements to form compounds.
Can argon form a liquid?
Liquid argon is tasteless, colorless, odorless, noncorrosive, nonflammable, and extremely cold. Liquid argon is a cryogenic liquid. Cryogenic liquids are liquefied gases that have a normal boiling point below –130°F (–90°C). Liquid argon has a boiling point of –303°F (–186°C).
Is argon heavier than air?
A Noble gas 1.38 times heavier than air The size and density of the argon molecule is what makes this element ideal for multiple uses.
What is the critical pressure of argon?
705.6 psia
| Molecular Weight: | 39.948 |
|---|---|
| Critical Temperature: | -188.5° F |
| Critical Pressure: | 705.6 psia |
| Critical Density: | 0.536 g/ml |
| Latent Heat of Vaporization @ b.p. | 39.13 cal/g |
Is argon liquid solid or gas?
Argon is colorless, odorless, nonflammable and nontoxic as a solid, liquid or gas. Argon is chemically inert under most conditions and forms no confirmed stable compounds at room temperature.
Can you breathe argon?
Inhalation: This gas is inert and is classified as a simple asphyxiant. Inhalation in excessive concentrations can result in dizziness, nausea, vomiting, loss of consciousness, and death.
Is argon heavier than nitrogen?
Argon versus Nitrogen Argon has a density of 0.1 lb/ft3 and nitrogen is 0.07 lb/ft3 or about 40% heavier per cubic foot than nitrogen. Therefore, argon will tend to sit on top of a liquid column and not readily diffuse with air. In almost all other uses of the gases, nitrogen is the better choice.
What color is Argon?

What happens when argon is dissolved in water?
Consequently, argon does not react with water. Argon has a water solubility of 62 mg/L at 20 oC and pressure = 1 bar. Clathrates contain argon and release the element upon dissolution. Argon does not remain dissolved in water, at least not in higher than normal concentrations.
What kind of compounds can argon react with?
Argon is generally non-reactive because it is a noble gas, having a complete outer valence electron shell. It will form compounds in extreme conditions, and has been found to react with hydrogen, fluorine, carbon, and tungsten.
Are there any health effects from drinking argon?
The element is not a dietary requirement. Argon is physiologically ineffective. Health effects from argon present in drinking water are not expected. The only health effect that may be of importance is argon accumulation in air that is breathed in, leading to oxygen deprivation and asphyxiation.
What are the dissolved gases in drinking water?
Natural and drinking water are in equilibrium with the air, and so will contain dissolved gases such as nitrogen, oxygen and carbon dioxide. What are the likely Gases in Purified Water? The main gases dissolved in purified water are oxygen and nitrogen, carbon dioxide, plus traces of inert gases, all in equilibrium with ambient air.
