Explaining with examples the uses of ionic and covalent compounds in daily life
Ionic and Covalent Compounds
5.7
Ionic and Covalent Compounds
Example of Ionic and Covalent Compounds
Ionic Compound
Covalent Compound
Salt
Ice
Properties of Ionic Compound
Ionic bond
Strong bond due to the electrostatic force.
The ions are arranged in orderly manners.
Propeties of Covalent Compounds
Covalent bond
The covalent compound consists of simple molecules.
The intermolecular force is weak.
The Difference between Physical Properties of Ionic Compound and Covalent Compound
Ionic Compound
Covalent Compound
Volatility
Non- volatile
Volatile, can change to vapour when heated
Electrical Conductivity
Conduct electricity in the molten or aqueous state
Does not conduct electricity
Solubility
Soluble in water, and polar solvent but insoluble in the organic solvent
Soluble in the organic solvent, but insoluble in water
Melting and Boiling Point
High
Low
The Difference between The Simple Molecular Structure and Giant Molecular Structure in Covalent Compounds
Simple Molecule
Component
Giant Molecule
Water,
\(H_2O\)
Carbon dioxide,
\(CO_2\)
Example
Silicone dioxide,
\(SiO_2\)
Small and simple structures can be found in the form of solids, liquids or gases.
Structure
Very large structure, usually exists as solids.
Covalent bonds are strong in the molecules and Van der Waals attraction forces between molecules are weak.
Chemical Bond
Strong covalent bonds in the molecules only.
No Van der Waals attraction forces between molecules because of its giant structure.
Low because only little heat is required to overcome the weak Van der Waals attraction forces between molecules.
Melting Point and Boiling Point
High because a lot of heat is required to break the strong covalent bonds.
