Ingredients

  • 200 g Washing soda (sodium carbonate)
  • 100 ml Water
  • enough to bubble through solution Carbon dioxide source (dry ice or CO2 generator)

Method

  1. Note: True from-scratch baking soda requires industrial Solvay process or natural trona mining. Home version uses washing soda + CO2.
  2. Dissolve washing soda (sodium carbonate) in 100 ml warm water → stir until clear.
  3. Bubble carbon dioxide through solution (use dry ice in a container with tube, or ferment yeast/sugar mix to produce CO2 and pipe gas in).
  4. Continue bubbling CO2 for 30–60 minutes → sodium bicarbonate (baking soda) will precipitate as white solid.
  5. Filter precipitate through fine cloth or coffee filter → rinse lightly with cold water to remove excess carbonate.
  6. Dry precipitate in low oven (50 °C) or air-dry completely (24–48 hours).
  7. Grind dried baking soda to fine powder if needed → store in airtight container.
  8. Test: mix small amount with vinegar — should fizz vigorously.
  9. Makes ≈150–180 g — homemade baking soda for baking, cleaning, or deodorizing.
