Bases are widely used in both laboratory and everyday applications. Some common examples of bases include:
Strong bases:
- Sodium hydroxide (NaOH): Used in soap making, paper industry, and drain cleaners
- Potassium hydroxide (KOH): Used in liquid soaps and alkaline batteries
- Calcium hydroxide [Ca(OH)₂]: Also known as slaked lime, used in whitewashing and water treatment
Weak bases:
- Ammonia (NH₃): Commonly used in cleaning agents and fertilizers
- Magnesium hydroxide [Mg(OH)₂]: Found in antacids (milk of magnesia)
- Aluminium hydroxide [Al(OH)₃]: Used in antacids and water purification
Everyday examples:
- Soap and detergents
- Baking soda (sodium bicarbonate, NaHCO₃)
- Toothpaste (mildly basic to neutralize acids in the mouth)
In simple terms:
Bases range from strong industrial chemicals to mild substances used in daily life, many of which help neutralize acids.
