Usually, when a salt anhydrate is treated with water, its crystalline structure will reappear. Many solids are crystalline when the water of hydration, or water of crystallization is present. If you vaporize this away with heat, the crystalline structure collapses and you are usually left with a powdery anhydrate. Add water and it re-crystallizes. Be careful though: adding the water back will also release the heat you put into it to remove it. So adding the water is an exothermic process.

What turns anhydrous ammonia to liquid?
Anhydrous ammonia turns into liquid form when it is subjected to pressure. This process is known as compression, which increases the density of the ammonia gas molecules and transitions it into a liquid state.
What is the expansion ratio for anhydrous ammonia?
The expansion ratio for anhydrous ammonia is about 850:1. This means that the volume of liquid anhydrous ammonia will expand to about 850 times its original volume when it vaporizes.
Can anhydrous ammonia become liquid ammonia?
Anhydrous ammonia is typically stored as a gas under pressure, but it can be liquefied by compressing it at a temperature below its critical temperature of 132.4 °F. Liquid ammonia requires pressure to remain in its liquid state, and it is often used as a refrigerant or in industrial processes.
What is anhydrous ammonia?
Anhydrous ammonia is a compound made of hydrogen and nitrogen that is commonly used as a fertilizer due to its high nitrogen content. It is stored and transported in liquid form but becomes a gas when released into the atmosphere. Anhydrous ammonia is highly toxic and must be handled with caution.
What is temperature of anhydrous ammonia?
The temperature of anhydrous ammonia is typically around -33 degrees Celsius when stored under pressure. It is a colorless gas at room temperature and pressure, but is often compressed into a liquid form for easier transportation and storage.

Liquid samples
Which of the liquid sample is most likey subtances?
Liquid samples are most likely to evaporate when temperature is increased.
What happens when sodium is treated with ammonia?
When sodium is treated with ammonia, the sodium dissolves in the liquid ammonia to form a deep blue solution called sodium amide, along with the release of hydrogen gas. This reaction is highly exothermic and should be carried out with caution due to the potential for a violent reaction.
Why are 2 layers of liquid formed in lucas test?
The Lucas test is used to determine the number of alkyl groups present in a compound. It is based on the fact that the compound to be tested is mixed with Lucas reagent, which is a solution of anhydrous zinc chloride in concentrated hydrochloric acid. If the compound has one alkyl group, then a single layer of liquid is formed. If the compound has two alkyl groups, then two layers of liquid are formed.
What chemical reaction is juice?
Juice is not a reaction; it is a liquid mixture.
Which type of samples analysed by hplc?
High-performance liquid chromatography (HPLC) is commonly used to analyze a wide range of samples, including pharmaceuticals, food and beverages, environmental samples, and biological samples such as proteins, amino acids, and nucleic acids.
Is liquid nitrogen supposed to be left on the skin after treatment?
Nitrogen must be cooled to a very low temperature to become liquid nitrogen. At room temperature, liquid nitrogen will change from the liquid phase to the gas phase. Therefore, if the skin is treated with liquid nitrogen, the liquid nitrogen will almost instantly become a gas and evaporate away from the skin. It is impossible to "leave" it on the skin, as this reaction is almost instantaneous and no liquid nitrogen is left behind.
