Frequently Asked Questions
1. Is sodium bicarbonate safe for daily use?
Yes, it is generally safe in small quantities, especially in food and personal care. Industrial use should follow safety guidelines.
2. Can I use sodium bicarbonate as a pesticide?
Yes, it helps repel ants and fungi, making it a natural alternative to chemical pesticides.
3. How is sodium bicarbonate different from baking powder?
Baking powder contains sodium bicarbonate plus an acidifying agent. Sodium bicarbonate alone needs an acid to activate.
4. Does sodium bicarbonate expire?
Yes, while it doesn’t spoil, it loses effectiveness after prolonged storage or exposure to moisture.
5. What industries benefit most from sodium bicarbonate?
Food, pharmaceuticals, agriculture, water treatment, and fire safety benefit the most due to its versatility.
