Design an activity to prove that ionic compounds have high boiling points.
Answers
Answer:
(i) Ionic compounds have high melting and boiling points.
(ii) Ionic compound are soluble in water.
(iii) Ionic compounds conduct elecincity in molten state.
(b) Show the formation of MgO by transfer of electrons.
Explanation:
a) (i) Ionic compounds have high melting and boiling points. It is because of strong force of attraction between oppositely charged ions, therefore high energy is required to break the metallic bonds between ions.
(ii) Ionic compounds are soluble in water because they form ions in aqueous solutions.
(iii) tonic compounds conduct electricity in molten state and in aqueous solution because ions carry current. The movement of ions takes place towards oppositely charged electrode in electric field.
(b) Formation of MgO:
For this, open the attachment.
Answer:
Heating of NaCl
Explanation:
We could take Sodium Chloride (NaCl) and heat it under flame.
Then we will observe that a large amount of energy is needed to break the strong inter ionic electrostatic forces of attraction.
