Bases:
Bases are substances that produce hydroxide ions (OH⁻) when dissolved in water. Strong bases dissociate completely, while weak bases dissociate partially in water.
Examples:
1. Sodium hydroxide (NaOH) – Used in soap manufacturing.
2. Potassium hydroxide (KOH) – Used in alkaline batteries.
3. Ammonium hydroxide (NH₄OH) – Used in household cleaners.
Properties of Bases:
1. Taste: Bases have a bitter taste.
2. Texture: Bases feel slippery or soapy to the touch.
3. Effect on Litmus Paper: Bases turn red litmus paper blue.
4. Reaction with Acids: Bases react with acids to form salt and water.
5. Electrical Conductivity: Bases conduct electricity in aqueous solutions due to the presence of OH⁻ ions.
