Sodium bicarbonate (chemical formula NaHCO₃) is a white crystalline powder commonly known as baking soda.
🧪 What it is
It’s a mild alkaline compound that reacts with acids to produce carbon dioxide gas (bubbles).
🍰 Common uses
- Baking: Helps cakes and bread rise when mixed with acidic ingredients
- Cleaning: Removes stains, odors, and grease
- Antacid: Can temporarily relieve heartburn by neutralizing stomach acid
- Deodorizing: Used in fridges, shoes, and carpets to absorb smells
⚗️ How it works in baking
When baking soda reacts with an acid (like lemon juice, vinegar, or yogurt), it produces CO₂ gas, which creates bubbles and makes baked goods fluffy.
⚠️ Safety note
- Safe in small amounts for food use
- Too much can cause a salty/bitter taste or stomach upset
- Should be used carefully as a home remedy for acidity, not as a long-term treatment
