- Bicarbonate of Soda (Baking soda)
- A glass, tall and straight
- Food colour
WHAT TO DO:-
Add a tea-spoon of baking soda into the glass. Then add some vinegar to it.
Bubbles erupt out of the glass when the soda comes in contact with the vinegar.
WHY THIS HAPPENS:-
This happens because the bicarbonate of soda is a compound of sodium, hydrogen, carbon and oxygen. In the chemical reaction, it breaks up when it comes in contact with the vinegar. The carbon and oxygen seperate from the other elements. Together they form a gas, carbon dioxide.
Try this experiment with detergent powder and you will find more bubbles erupting from the glass. Can you explain why this happens?
