How will you know a reaction has taken place?
What might you see?
Experiment Instructions
Place your baking soda into containers. A muffin tray or similar is perfect for this. Make sure you add the same amount to each container.
Can you predict which substances will react and which won’t?
Use a pipette to add each substance to a different container of baking soda, make sure you use the same amount of each substance.
Record which reacts and which do not react. What do you notice about the substances that react?
Can you think of anything else to test?
Why does this happen?
Bicarbonate of soda – baking soda is alkali which reacts with acids to produce carbon dioxide.
Extension Ideas – More Science for Kids
Can you test the substances that reacted with the baking soda again? Which gives the strongest reaction?
