Indicators can be used to find weither a solution is acidic or basic
With just three easy steps you can have your very own indicator!
When the red cabbage juice comes in contact with an acid it turns red. When the juice turns blue it is a base. When the PH drops below 7 the solution turns red. When it goes above 7 it begins to turn blue.
As you can see cabbage juice was a great indicator for these solutions. The vinegar was the most acidic and became the clearest red. The baking Soda was the most basic and was the bluest.
