Is Na₂CO₃ a basic salt?

Yes, sodium carbonate (Na₂CO₃) is a basic salt because it is formed from a strong base (NaOH) and a weak acid (H₂CO₃). When a strong base reacts with a weak acid, the resulting salt shows basic properties in water. Sodium carbonate is such a salt.

Reaction

2NaOH (strong base) + H₂CO₃ (weak acid) → Na₂CO₃ (basic salt) + 2H₂O

Properties of Na₂CO₃

• Alkaline in nature.
• Turns red litmus blue.
• Used in soaps and detergents.
