Acid and base test with red cabbage 2019-04-07

Doing simple experiments with things you can find in your kitchen is cool. We like doing acid base tests with red cabbage. It is a simple harmless thing you can do with all age groups. And they can easily see that something happens. They can all take part. In this experiment, we mix red cabbage, boiling water and Sodium hydroxide. That strong base will change the colour to first green, then blue then end at yellow. Then the other glass is red cabbage, boiling water and lemon. That acid mixture will turn red.
