What is called the property of a salt by which it absorbs water from the atmosphere?

The property of a salt that enables it to absorb water from the atmosphere is known as hygroscopicity.


What are hydrates and what is hydration?

Some salts have a property called "hygroscopy". This means that they absorb water from the air in a preset ratio (like, 5 molecules of water for every 2 units of the salt for example). They give this water off when heated. Therefore, there are actually two forms of the salt, they "hydrate" or "hydrous" form, which has the water, and the "anhydrate" or "anhydrous form", which does not. These two forms can have surprisingly different properties. Hydration is the process of going from an anhydrate to a hydrate (the source of the water doesn't matter, so don't say it's "absorbing water from the air").


How can you obtain hydrated salt?

To obtain hydrated salt, you can dissolve an anhydrous salt in water and then evaporate the water to grow hydrated crystals. Alternatively, you can mix the anhydrous salt with a calculated amount of water to form a solution with a specific hydration level.


When a salt crystal is dropped into water the water molecules are attracted to the salt's ions and will surround them What is this called?

This process is called dissolution. Water molecules surround the individual ions of the salt crystal, separating them from the crystal and forming a solution.


Does salt and water combine to make a compound?

No, salt and water do not chemically combine to form a new compound. Salt (sodium chloride) dissolves in water to form a solution, where the salt ions are surrounded by water molecules through a process called hydration.

Salt dissolves in water because it is?

polar and forms hydration shells with water molecules. This disrupts the ionic bonds holding the salt together, allowing it to dissociate into its constituent ions, sodium and chloride.


How does the consumption of salt during fasting affect the body's hydration levels and overall health?

Consuming salt during fasting can affect the body's hydration levels by helping to retain water and maintain electrolyte balance. However, excessive salt intake can lead to dehydration and other health issues. It is important to consume salt in moderation during fasting to support hydration and overall health.


What is the amount of water in salt called?

It's called "water of hydration".

When powdered salt is mixed with water it forms what?

When powdered salt is mixed with water, it forms a salt solution. The salt particles dissolve in the water, creating a homogeneous mixture.


Are cystals of salt really dry?

Not necessarily. There could be water molecules (hydration) present in the crystal lattice.


What Metal hydroxide plus acid?

When a metal hydroxide reacts with an acid, it forms water and a salt. The metal from the hydroxide forms the cation of the salt, while the anion from the acid forms the anion of the salt. This reaction is known as neutralization.
