Mixing Baking Soda and Citric Acid

Baking soda is known as a “base,” and citric acid is an “acid” – these chemicals react and create the gas carbon dioxide! When you add soap to the mixture, the carbon dioxide becomes foam because the gas gets trapped in small soap pockets!

Equipment

  • Beaker, Flask, Baking Soda, Citric Acid, Dish Soap, Food Coloring, Measuring Spoon

Materials

  • 1 Tablespoon Baking Soda
  • 1 Tablespoon Citric Acid
  • 50 ML Warm Water
  • 7 drops Food Coloring
  • 4 drops Dish Soap

Instructions

  • 1. Start by adding 1 Tablespoon of baking soda and 1 Tablespoon of citric acid to the flask.
    2. Next, add 7 drops of food coloring to the flask.
    3. Add 4 drops of dish soap to the flask and set aside.
    4. Measure 50 ML of warm water, add to the flask, and watch the liquid. Observe what happens to the Baking Soda, Citric Acid, and Dish Soap now that the Water has been added to the mix.

Notes

Pro Tip: Add an extra Tablespoon of Citrus Acid for an enormous explosion :)
