Iconic compound short notes​

Answer 1

Ionic compounds

The compounds formed in the manner by transfer of electrons from a metal to a non metals are known as ionic compounds or electrovalent compounds. For example magnesium chloride.

Genral properties of ionic compound are as follows:

• Physics nature: Ionic compounds are solids and are somewhat hard because of the strong force of attraction between the positive and negative ions. These compounds are generally brittle and break into pieces when pressure is applied.
• Melting and boiling point: Ionic compounds compounds have high melting and boiling point because a considerable amount of energy is required to break the strong inter ionic interaction.
• Solubility: Electrovalent compounds are generally soluble in water and insoluble in solvents such as kerosene and petrol etc.
• Conduction of electricity: A solution of ionic compound NDin the solid state do not conduct electricity because movement of the ions in the solid is not possible due to their rigid structure. But ionic compounds conduct electricity in the molten state.
