Acids and Bases: Cabbage Juice Indicator

Getting back to the beginning of the unit, learners use reactions with red cabbage juice to determine if solutions are acidic, neutral, or basic. This is a straightforward and classic investigation, but what you will appreciate is the...

Now that your science class has experimented with pH indicator and identified acids and bases, they attempt to get the cabbage juice indicator back to its original color. This is done through neutralization of the acids and bases that...

Students investigate about acids, bases, and pH and relate this information to the problem of acid deposition. They use pH paper, students test common household substances to determine whether they are acidic, basic, or neutral. Pupils...

Learners explore the use of acid and base pH indicators. The teacher saturates an indicator sponge with congo red solution. Afterwards, the sponge is placed in a blue base solution. Students observe that the blue sponge actually turns...

An acid/base indicator that's made of blended red cabbage and water is used to demonstrate the various reactions that an acid/base solution goes through when some carbon dioxide gas is added. The best way to add the carbon dioxide is to...

In this video segment, the ZOOM cast demonstrates how to use cabbage juice to find out if a solution is an acid or a base.

Young chemists learns about acids and bases by coming up with a solution that will test for each. They also access the Internet to perform research. They are encouraged to contact learners in other schools by conducting the experiment at...

What happens when you mix baking soda and lemon juice? Watch the ZOOM cast launch a rocket using kitchen chemistry. [3:26]

This experiment is for all the kids out there who love boiled cabbage. Even if you don't like cabbage, perhaps you will like this amazing color-changing liquid you can make with cabbage. You'll learn which solutions around your house can...
