Jazzy Lemonade

Wit-Bit

In this post, I will be explaining how to make a color changing fizzy lemonade! This is an easy experiment that involves a lot of science, so let’s get started. Here’s what you will need: raspberry lemonade, baking soda, a glass, and a spoon.

First, put the lemonade in a glass. Have your kids observe the color of the lemonade. Then stir the lemonade and add a sprinkle of baking soda. As you stir, you will start to see bubbles forming, and the lemonade is getting fizzy. As you stir more, you will see the color of the lemonade fade.

How did this happen?

Lemonade is an acid and baking soda is a base! When the baking soda got mixed into the lemonade, an acid-base reaction occurred! This reaction caused carbon dioxide gas to be created, which made the lemonade fizzy.

Raspberry has a pigment called Anthocyanin. This pigment is an indicator, which changes color when it is acidic or basic. So, when the baking soda was added, the lemonade was becoming more basic, causing the color to change.

In the end, we get a color changing fizzy lemonade that we can drink!
