Making Lemon Soda!
Do you like drinking soda? Many people love the bubbly, fizzy, sensation of soda drinks on their tongues. But how do the bubbles, fizz, and taste get into the water? In this project, you will use baking soda, citric acid, and sweetener to create your very own soda.
Baking soda, 8-ounce box1 lemon per child
Plastic clear 10 oz. cup
1/4 teaspoon measure
1 Wooden coffee stirrer
Paper towels (1 roll)
Cut the lemon in half.
Squeeze as much of the juice from the lemon as you can into the glass.
Measure out how much lemon juice you squeezed. Pour it back in your cup and measure an equal amount of water to add in your lemon juice.
Pour in an equal amount of water as lemon juice.
Stir in the 1/4 teaspoon of baking soda.
Observe as you are mixing it.
Give the mixture a taste and add in some sugar if you think it needs to be sweeter.
Try this experiment using a variety of different fruit juices and see the different results produced. Which fruit had the biggest reaction?
How does it Work?
When you mix baking soda and citric acid together with water, a chemical reaction takes place. The chemical reaction that occurs when you combine baking soda and citric acid produces carbon dioxide, water, and sodium citrate. The fizz that bubbles up in your soda drink is carbon dioxide.
To get the fizz in the soda you buy from the store, companies put carbon dioxide right into the soda. To get that extra bubbly fizzy drink, more carbon dioxide is put into the liquid soda than can be dissolved in the liquid. Since this carbon dioxide can’t dissolve it sits in the air space on top of the liquid. This carbon dioxide escapes when you open the bottle making a little “hissing” sound.
