Question

What type of reaction occurs when an alkali metal combines with water? 

  1. Decomposition 
  2. Exothermic 
  3. Endothermic 
  4. Neutralisation

hintHint:

Heat is evolved when alkali metals react with water.

The correct answer is: Exothermic 


    • Alkali metals show vigorous reaction with water.
    • Sodium is very reactive when it comes in touch with water it catches fire.
    •  Hence, exothermic reaction occurs when an alkali metal combines with water.
