Yes, calcium chloride is hygroscopic, meaning it has the ability to absorb moisture from the air. This property makes it effective as a desiccant and is often used for dehumidifying and controlling humidity in various applications. It readily attracts water vapor, which can lead to its deliquescence, where it dissolves in the absorbed moisture.

Why is calcium chloride used in dehumidifier?
Calcium chloride is hygroscopic, meaning that it absorbs water from the air. This is the job of a dehumidifier.
What is an example of a hydrous salt?
An example of a hygroscopic salt would be calcium chloride, a salt that absorbs water from the atmosphere to form a saturated solution
How do you separate ammonium chloride from a mixture containing ammonium chloride and anhydrous calcium chloride?
To separate ammonium chloride from a mixture with anhydrous calcium chloride, you can add water to the mixture. Ammonium chloride is soluble in water, while anhydrous calcium chloride is hygroscopic and will absorb moisture. After adding water, you can filter the mixture to remove the insoluble calcium chloride, leaving the dissolved ammonium chloride in the filtrate. The ammonium chloride can then be recovered by evaporating the water.
How can salt act as a desiccant?
Yes, desiccation is in salt to make thing mummified.
Why anhydrous calcium chloride is not called calcium chloride?
Anhydrous calcium chloride refers specifically to the form of calcium chloride that contains no water molecules, distinguishing it from hydrated forms that include water in their crystalline structure, such as calcium chloride dihydrate. The term "anhydrous" is used to emphasize the absence of water, which significantly affects the compound's properties and applications, such as its hygroscopic nature and use as a desiccant. Thus, while both forms are calcium chloride, the prefix "anhydrous" is necessary for clarity in chemical contexts.
Why is calcium chloride used in dehumidifier?
Calcium chloride is hygroscopic, meaning that it absorbs water from the air. This is the job of a dehumidifier.
What does the difference between the few crystals of anhydrous calcium chloride and a few crystals of Glauber's salt when are exposed to the atmosphere?
Calcium chloride easily absorb water, it is hygroscopic.
What happens when anhydrous calcium chloride is exposed to the atmosphere for about 2 days?
Anhydrous calcium chloride is a hygroscopic compound, meaning it readily absorbs moisture from the atmosphere. When exposed to air for an extended period, it will pull in water vapor and dissolve, forming a solution of calcium chloride and water. This process is exothermic, generating heat as it occurs.
What are the effects of water in calcium chloride?
Water reacts with calcium chloride to form calcium hydroxide and hydrochloric acid. This reaction releases heat and can generate steam. Calcium chloride is hygroscopic, meaning it absorbs water from the surrounding environment, making it effective for dehumidifying and drying applications.
When anhydrous calcium chloride is kept in open air it forms an aqueous solution why?
Anhydrous calcium chloride readily absorbs water vapor from the air due to its hygroscopic nature. This absorption of water leads to the dissolution of the calcium chloride in the absorbed water, forming an aqueous solution.
Where did the water came from in the case of calcium chloride?
Calcium chloride is a deliquescent substance, meaning it absorbs moisture from the air to form a solution. The water in calcium chloride comes from this process of attracting and binding water molecules from the surrounding environment.
What is an example of a hydrous salt?
An example of a hygroscopic salt would be calcium chloride, a salt that absorbs water from the atmosphere to form a saturated solution

What are the differences between calcium chloride and magnesium chloride in terms of their properties and applications?
Calcium chloride and magnesium chloride are both salts commonly used for de-icing roads and as drying agents. However, they have different properties and applications. Calcium chloride is more hygroscopic, meaning it absorbs more water from the air. It is also less corrosive than magnesium chloride. Calcium chloride is often used for dust control, concrete acceleration, and food preservation. Magnesium chloride is less hygroscopic and more corrosive than calcium chloride. It is commonly used for de-icing roads and as a supplement for magnesium in agriculture and medicine. In summary, calcium chloride is less corrosive and more versatile in its applications, while magnesium chloride is primarily used for de-icing and magnesium supplementation.
Is sodium chloride hygroscopic?
Sodium chloride has a rare dihydrate, obtained from cold solutions - NaCl.2H2O.
