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

Do ionic solids conduct electric current in the solid state?

Give reason why? Sugar solutions do not conduct electricity.

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

(a) Show the formation of magnesium chloride and sodium chloride by transfer of electrons. (b) Identify the ions present in these compounds. (c) Why do ionic compounds not conduct electricity in the solid state?

Give reasons why? Ionic compounds are soluble in water

Give reasons why? Carbon tetrachloride does not conduct electricity.

Can sodium chloride conduct electricity in the solid state ?

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.

Give reasons why? Ionic compounds are crystalline solids.

Explain why : sodium chloride does not conduct electricity in the solid state but conduct in the fused state or in aqueous solution
