Explain the following:
Covalent compounds do not conduct electric current in the fused state, whereas ionic solids do.

Give reasons why? Ionic compounds do not conduct electric current in the solid state

Do ionic solids conduct electric current in the solid state?

Explain the following: Covalent compounds are insoluble in water.

Explain the following: Ionic compounds conduct electricity.

Explain the following: HCl is a covalent compound still it conducts electricity in its aqueous state.

Covalent compounds generally do not conduct electricity. Give reason.

Explain the following: Covalent solids are usually soft.

Explain the following: (a) Sodium chloride is an ionic compound which does not conduct electricity in solid state whereas it does conduct electricity in molten state as well as in aqueous solution. (b) Reactivity of aluminium decrease if it is dipped in nitric acid. (c) Metals like calcium and magnesium are never found in their free state in nature.

Which of the following covalent solid is the conductor of electricity ?

Can sodium chloride conduct electricity in the solid state ?
