Question

From the following statements write those applicable to
ionic compounds?
a) Usually do not dissolve in water.

b) Conduct electricity in the molten state and aqueous solution.

c) Generally not a conductor of electricity.

d) Exists in the solid state​

Answer 1

Answer:

b and c are correct

Explanation:

ionic bond is soluble in water

Answer 2

From the following statements those applicable to ionic compounds are b) Conduct electricity in the molten state and aqueous solution. d) Exists in the solid state

• Since ionic compounds are polar in nature so they can easily get dissolved in water as they attract the opposite ions. Though there are few exceptions here but in general most of ionic compounds dissolve in water. Hence, option a is not correct.
• Ionic compounds only conduct electricity when they are in the molten state because this allows the ions to move freely. Hence, option b is correct.
• In general, ionic compounds are in solid state so they don't conduct electricity as ions are held together tightly. It's only when they are in free state ions are able to move. Hence, c is not completely correct
• Ionic compounds exists in solid state as electrostatic forces are build up tightly between the anions and cations. Hence, option d is correct.
