• It is a white crystalline powder that is commonly used as a leavening agent in baking.
• Sodium hydrogen carbonate reacts with acidic components in batter, releasing carbon dioxide gas which helps dough rise.
• It is also used in various household cleaning and deodorizing applications due to its mild abrasive properties and ability to neutralize odors.

Additional Information

• Chemical Properties:
  • When heated, sodium hydrogen carbonate decomposes to form sodium carbonate, water, and carbon dioxide.
  • It is amphoteric, meaning it can react with both acids and bases.
• Uses in Medicine:
  • Sodium bicarbonate is used as an antacid to treat acid indigestion and heartburn.
