true or false
Some compounds, when they crystallize out of water, use water to form part of their crystalline structure and are then call hydrates.
Homework Answers
There are many inorganic salts which contain water of crystallization as a part of their crystal; e.g, CuSO4.5H2O. Such salts crystallise out from water will contain water of crystallization and are called hydrous salt or hydrates. Thus, given statement is correct

2. Water forms many solid inclusion compounds, called clathrate
hydrates. In clathrate hydrates water molecules are arranged to
form polyhedral cages around the enclosed molecules or atoms. An
example of such a cage is shown. (a) What do the corners of the
structure represent? What do the edges represent? (4) (b) How do
enclosed molecules, such as methane or dihydrogen, interact with
the cage? (E.g., covalent bonds, ionic interactions, etc.) (2) (c)
