Not only NaOH, can be any other compound that do not have any water molecule attached to it such as anhydrous CaCl2, Silica gel, anhydrous NaCl..
This is a covalent compound.
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 product that is left after heating a hydrate is an anhydrous compound. This means that the water molecules in the hydrate have been removed through the process of heating, leaving behind the anhydrous form of the compound.
Nickel(II) chlorate
A hydrated crystal in one that has water molecules trapped inside the crystal structure of some other compound, typically an ionic compound. The water is chemically combined with a substance in such a way that it can be removed, as by heating, without substantially changing the chemical composition of the substance. As a good example, copper sulfate is a commonly hydrated crystal. To show that it is hydrated, you would write CuSO4 . 5H2O. By putting a dot in between the two, it indicates that they are waters of hydration, not really part of the compound (you can remove them by heating the crystals). You can see in this case, there are 5 water molecules for each CuSO4.
For example uranyl nitrate may exist as an anhydrous compound.
A anhydrous ionic compound does not contain water. It is the dehydrated form of a hydrate.
CaSO4
Yes it is, it is without water!

This is a covalent compound.
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.
Aluminum Chloride - Anhydrous
because of ionic compound.
(of a substance, esp. a crystalline compound) containing no water.
The color of an anhydrous compound is sometimes different from the hydrated compound.
The product that is left after heating a hydrate is an anhydrous compound. This means that the water molecules in the hydrate have been removed through the process of heating, leaving behind the anhydrous form of the compound.
