Information Booster:

• Chemical name of Baking Soda → Sodium Bicarbonate (NaHCO₃)
• Chemical name of Baking Powder → Sodium Bicarbonate + Mild Acid (like tartaric acid)
• Antacid action → Neutralizes excess HCl in the stomach
• In soda-acid fire extinguishers → Produces CO₂ gas to stop fire

Additional Knowledge:

• Bleaching Powder → Calcium Oxychloride (CaOCl₂)
• Used for bleaching cotton, laundry, and disinfecting drinking water
• Hydrogen Peroxide (H₂O₂) is also used as a bleaching agent
