Volcano Experiment

Aim:

To see a reaction between an acid and base.

Equipment:

Washing up liquid, Vinegar, Cup or glass, Baking soda, Food colouring- Red & Yellow or orange

Method:

1 Make sure your volcano is in the kitchen or outside

2 Add 2 tbsp full of baking soda

3 Add 1 tbsp of washing up liquid into the cup

4 Add a few drops of the food colouring

5 Quickly pour in just under a quarter of a cup of vinegar.

Results:

You will see foam rising/coming out

Conclusion:
Mixing the acid (vinegar) and the alkali (bicarbonate of soda) and releasing bubbles of carbon dioxide CO2. The washing up liquid is just there to trap those bubbles so it flows over the ‘volcano’ like real lava!
