Uses of ionic and covalent compounds in our daily lives
Industrial, agricultural, medical and domestic use
The differences compounds properties
Electrical conductivity, solubility of compounds, melting point and boiling point
The properties of different compounds
Different compounds have different properties
Electrical conductivity of ionic compound (2)
In he molten state and aqueous solution, ionic compound can conduct electricity
Ionic compounds cannot conduct electricity in the solid state (1)
Ions cannot move freely because they are tied by strong electrostatic attraction forces
Ionic compounds cannot conduct electricity in the solid state (2)
Therefore, solid ionic compound cannot conduct electricity
Ionic compounds can conduct electricity in the molten state and aqueous solution (1)
Ions can move freely because electrostatic attraction forces have been overcomed
Ionic compounds can conduct electricity in the molten state and aqueous solution (2)
Therefore, molten or aqueous solution of ionic compound can conduct electricity
Covalent compounds cannot conduct electricity in all states (1)
Molecules in covalent compounds are neutral and do not carry any charge
Covalent compounds cannot conduct electricity in all states (2)
Therefore, covalent compounds do not conduct electricity in all states
