Common Bases
Examples include: Sodium Hydroxide (NaOH), Potassium Hydroxide (KOH), Calcium Hydroxide (Ca(OH)₂), and Ammonia (NH₃)
Properties of Bases
• Bitter taste
• Slippery to touch
• Turn red litmus paper blue
• pH greater than 7
Uses of Bases
• Soap and detergent production
• Antacids for stomach relief
• Cleaning products
• Food processing
Base Strength
Strong bases completely dissociate in water, while weak bases only partially dissociate.
Formation of Salt
Formation of Salt
Acid + Base → Salt + Water
Example:
HCl + NaOH → NaCl + H₂O
Common Salts
• Table Salt (NaCl)
• Baking Soda (NaHCO₃)
• Washing Soda (Na₂CO₃)
• Gypsum (CaSO₄)
Properties of Salts
• Most are crystalline solids
• High melting and boiling points
• Conduct electricity when dissolved
• Can be acidic, basic, or neutral
Uses of Salts
• Food seasoning and preservation
• Manufacturing chemicals
• Medicine and healthcare
• Agriculture and fertilizers
