activity 13: Home made fizzy drinks
From Thomas Green, aged 12
Ingredients:
 |
6 teaspoons of citric acid crystals
|
|
3 teaspoons of bicarbonate of soda
|
|
2 tablespoons of icing sugar
|
|
cordial
|
What to do:
|
Mix together 6 teaspoons of citric acid crystals with 3 teaspoons of bicarbonate of soda. Add 2 tablespoons of icing sugar.
|
|
Fill a glass with cordial and water then add 2 teaspoons of your citric acid-soda-icing sugar mix. This should fizz.
|
Why?
When the crystals dissolve in the water they form citric acid which reacts with the alkali bicarbonate of soda forming carbon dioxide gas bubbles giving the drink fizz. |
