Chapter 10.5, Problem 76SSC

Interpretation Introduction

Interpretation:

The composition of a hydrate compound needs to be explained.

Concept introduction:

On the basis of bonding, chemical compounds can be classified as ionic and covalent compounds.

Ionic compounds are composed of oppositely charged ions whereas covalent compounds are composed by equal sharing of electrons between bonded atoms.

Answer to Problem 76SSC

Hydrates are the compounds which are composed of ionic compound with water molecules associated with ionic compound.

Explanation of Solution

Hydrate compounds are the chemical compounds in which ionic compound is associated with number of water molecules. The water molecules are associated with each formula unit.

The name of hydrate is the name of the ionic compound with prefix of number of water molecules and followed by hydrate term. Some common example of hydrate compounds are $\text{MgSO}\text{.}{\text{7H}}_{\text{2}}\text{O}$ and $\text{CuSO}\text{.}{\text{5H}}_{\text{2}}\text{O}$.

Conclusion

Hydrates are the compounds which are composed of ionic compound with water molecules associated with ionic compound.
