About this science experiment

In this quick and easy experiment, we'll investigate the acid-base reaction that happens between citric acid and baking soda.

Materials

  • An orange
  • Paper towel
  • A knife
  • 2ml baking soda

Procedure

  1. Ask an adult to cut the orange into slices for you. This experiment works a little better with wedge-shaped slices (instead of circular slices).


  2. Use the paper towel to dry as much juice as possible off one of the orange slices.


  3. Dip one side of the dry orange slice into the baking soda so it forms a very thin layer.


  4. Holding the baking soda side away from your tongue (it doesn't taste too good!), take a bite of the orange. What happened?


Analysis and Conclusion

Hmm... it seems nobody's added a conclusion for this experiment yet. You can suggest one here.
