Question
With the help of a suitable example, explain how ionic compounds are formed State any three general properties of ionic compounds.
✓

Answer

Ionic compounds are formed when a metal and a non metal react with each other.ie, positive and negative charges. eg: Na(metal) + Cl(non memtal) - NaCl
Properties: Ionic compounds have a strong electrostatic force of attraction. They have high melting and boiling points. They can dissolve in other ionic compunds like water.

No chemical reaction takes place when granules of a rusty-brown solid A are mixed with the powder of another solid B. However, when the mixture is heated, a reaction takes place between its components. One of the products C is a metal and settles down in the molten state while the other product D floats over it. It was observed that the reaction is highly exothermic.
