5. Define ionic compound, write, its four properties.
Why do ionic compounds have high melting points? Give two
examples of ionic compounds.
Answers
Answer:
Ionic compound contains charge ions .
E.g,NaCl Crystal,MgCl etc
1) Conduct electricity by movement of either ions in solution/molten state
2)High melting and boiling point
3)Ionic compound are crystalline solids.
1)Need more enthalpy for segregation of positive and negative charge partical as inter spaces is much lower.
Explanation:
Ionic Compounds have high boiling and melting points as they're very strong and require a lot of energy to break. The electrostatic forces of attraction between oppositely charged ions lead to the formation of ions. Ionic compounds form crystals
Following are properties of ionic compounds:- They form crystals. They have higher enthalpies of fusion and vaporization than molecular compounds. They have high melting points and also high boiling points. They conduct electricity but only when they are dissolved in water.
