Define bases, write their properties and examples aswell.

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.
