What is a hydrated compound?

Solid inorganic compounds that have bound water molecules attached to the atoms, either coordinated to the molecule or directly to the metal atom. The water generally will not affect the chemistry (after all a lot of reactions take place in aqueous solvents anyway), but may affect the colour of the compound. It is termed water of crystallisation; and as the name implies the water molecules are bound in the lattice when crystallised. When writing a formula, it will look something like MgSO4.7H2O, meaning magnesium sulfate has 7 water molecules bound to it, and is a hepta-hydrate. The water can be removed simply by heating it up. Technically the compound is "wet" even though it will look and feel like a dry powder. Anhydrous compounds are ones that do not contain any coordinated water. Anhydrous compounds that will coordinated a large number of water molecules are widely used to "dry" mixtures where a little water may contaminate an organic solvent as the water binds to the substance, but the substance remains in a powdered form, often clumping, so is easily removed by filtration.

What does the name hydrate indicate about its composition?

The name "hydrate" indicates that the compound contains water molecules attached to its structure. In hydrates, water molecules are typically loosely bound to the compound through hydrogen bonding. The water content can vary, but it is usually expressed as a ratio to the compound in the formula.

A compound that has a specific number of water molecules bound to its atoms?

The term for a compound that has a specific number of water molecules bound to its atoms is a hydrate. In a hydrate, water molecules are typically attached to the compound through weak chemical bonds known as hydrogen bonds. The number of water molecules in a hydrate is represented by a numerical prefix in the compound's name, such as in CuSO4•5H2O, where there are five water molecules bound to each copper sulfate molecule.

What is the upper and lower bound of 6800?

The upper bound of a number is the smallest whole number that is greater than or equal to the given number. In this case, the upper bound of 6800 is 6800 itself. The lower bound of a number is the largest whole number that is less than or equal to the given number. Therefore, the lower bound of 6800 is also 6800.
