Chemical raising agents


Learning
The aim of this session is to:
 demonstrate the reaction of baking soda with an
acid.

You will need:


 75g baking soda;
 200ml white vinegar;
 1 2 litre, clean, empty plastic bottle;
 1 regular party balloon.

Instructions:
1. Fill a balloon with the 75g of baking soda.
2. Pour 200ml of white vinegar into the empty
plastic bottle.
3. Taking great care, place the balloon over the
neck of the bottle, without allowing any baking soda to fall in.
4. Once secure, allow the baking soda to drop into the bottle and mix with the
vinegar.
5. Make sure to keep the balloon tightly over the neck of the bottle.
6. What can you observe happening in the bottle? What happens to the balloon?
Write down your observations.
7. Take care not to let the balloon burst! Remove it if necessary.

Questions
Think about these questions after you have completed the experiment:
 Which gas is produced through the reaction of baking soda and vinegar?
 What do you think would happen if you used water instead of vinegar?

Bonus scientific experiments


 Tie off the filled balloon and blow up another balloon, filling it with air (to about
the same size). Drop both balloons from a height. Which hits the ground first and
why?

 Place a thermometer in a cup and mix more baking soda and vinegar together.
Does the temperature go up or down?
