The term anhydrous means, does not contain water. H2O is the chemical formula for water. Hence, it is the opposite of anhydrous. It is the most hydrous of all substances.
The term anhydrous means without water. Some compounds, such as copper sulfate (CuSO4) have the capacity to absorb water, which becomes loosely attached to the ionic compound, at which point it is said to be hydrated; if you heat it you can drive off the water, at which point it becomes anhydrous. Hydrated copper sulfate is blue in color; the anhydrous form is white.
anhydrous
"Anhydrous" means "without water." What they mean by that is, the item in question hasn't absorbed any, usually from the air. So, pick any salt you like - NaCl is pretty common - and as long as it hasn't absorbed water, it's anhydrous. ------------------------------------------------------------------------------------------------------------------------------ An anhydrous salt doesn't contain water of crystallization. Example: MgSO4.7H2O is a hydrated salt (in this case a heptahydrate) and MgSO4 is the anhydrous form. A humid salt is not a hydrate and the term anhydrous is not adequate for a dried substance.
Anhydrous is the term for a hydrate with water heated off. when a hydrated salt is heated, it loses water of crystallization leaving an anhydrous salt.
The term "erg" can refer to a unit of energy in the centimeter-gram-second (CGS) system, where 1 erg equals 10^-7 joules. However, if you're referring to "ERGs" in a different context, please clarify. Anhydrous typically means "without water," often used in chemistry to describe substances that lack water of hydration. For example, anhydrous salts are those that do not contain water molecules in their crystal structure.
anhydrous
Asymptomatic means to be without symptoms.
A term that means without water is dehydrated. Dry, moisture-free, arid, and drought are all also terms that mean without water.
A medical term that means without skin is "dermatitis."
is it true
If you mean a compound containing water, the term would be hydrous or hydride, the same material without water would be "anhydrous" or "anhydride" Hope that helps
