Question
What type of reaction occurs when an alkali metal combines with water?
- Decomposition
- Exothermic
- Endothermic
- Neutralisation
Hint:
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.
