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").

What situations could occur in a hydrate?
Hydrates can experience dehydration when exposed to heat, causing them to lose water molecules and undergo a phase change. They can also undergo re-hydration when exposed to water vapor in the air, potentially leading to the formation of a hydrated compound again. Additionally, hydrates can exhibit shifts in color or physical properties due to the presence or absence of water molecules in their structure.
Can Copper Sulfate form multiple hydrates?
Yes, copper sulfate can form multiple hydrates with different amounts of water molecules attached to the copper sulfate compound. Common hydrates include copper(II) sulfate pentahydrate (CuSO4·5H2O) and copper(II) sulfate trihydrate (CuSO4·3H2O).
Are gas hydrates bad for the environment?
No. Gas hydrates are a natural part of the environment. The play an important role in moderating the way in which carbon is cycled between sediment, oceans, and the atmosphere. But like any part of the environment, disruption of their natural state/behavior can create imbalances for which nature is "prepared". However, given where hydrates are, such unnatural disruptions are extremely unlikely
Do covalent compounds form hydrates?
No, covalent compounds do not typically form hydrates. Hydrates are formed when ionic compounds interact with water molecules to form a crystalline structure with a specific number of water molecules associated with each formula unit of the compound. Covalent compounds are more likely to interact with water through hydrogen bonding or other non-specific interactions.
What are gas hydrates used for?
Gas hydrates are a potential future energy source, as they contain large amounts of methane that could be extracted for use as fuel. They are also studied for their possible role in climate change, as they could release methane - a potent greenhouse gas - if disturbed or warmed. Additionally, gas hydrates have been investigated for their potential applications in gas storage and separation processes.
Why cant all hydrates be heated?
Not all hydrates can be heated because some hydrates are thermally unstable, meaning they can decompose or lose water molecules when heated. This can lead to chemical reactions and changes in the properties of the hydrate. Heating certain hydrates beyond a certain temperature can also result in the loss of water of hydration, altering the structure and properties of the compound.

When cement is allowed to set why does it give off heat?
The hydration of cement is an exothermic reaction. Three exothermic reactions are important: - hydration of gypsum and tricalciumaluminate - hydration of dicalciumsilicate - hydration of tricalciumsilicate
Are hydrates and an-hydrates different on a molecular level?
no they are not
How are hydrates used?
hydrates are mainly used in artificial radioactivity and ............
Do all hydrates lose water?
Yes, all hydrates lose water after heating.
What is super hydration?
Super Hydration is a health philosophy based upon consuming a gallon of water or more per day for the purposes of detoxification. Proponents believe that the water should be cold, as this is thought to increase the metabolism. Here is a detailed article: such as hydration is the 69er of the sex world. it hydrates the muscles in use and give great plesure, this would be great for sucking someone off http://www.drdarden.com/readTopic.do?id=383704

What sport beverage works the best for replenishing vitamins?
The most popular sports drink is Gatorade. It taste good and provides good hydration after a work out. But perhaps the best and cheapest would be water, which hydrates the body as well as any sports beverage.

Why are Methane hydrates bad for boats?
Methane hydrates are not inherently bad for boats. However, if methane is released from hydrates in large quantities in the water, it can reduce the water density and potentially lead to buoyancy issues for boats. Methane hydrates can also contribute to the formation of gas seeps, which can be hazardous for boats navigating in those areas.
