Is it an acid, base, or neutral? Make your own acid-base indicator from red cabbage, then test various household substances. Acids and bases are classes of materials that have different properties.

Colourful indicators from flower petals at the House of Science. Photo: SUPPLIED This week we conclude our home chemistry series with a lovely colourful experiment. The background Acid-base chemistry ...

A crash course on the basic differences between acids and bases. A crash course on the basic differences between acids and bases, complete with a classroom-friendly experiment demonstrating the ...

An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...

Experiment #1 – Is it an acid, base or neither? The pH scale (which ranges from 0 to 14) gives us the ability to understand how acidic (pH lower than 7) or basic (pH higher than 7) an item is. We can ...

Materials Needed: red cabbage leaf, water, blender, bowl and a long cylinder to pour the ingredient in it. Put the red cabbage leaf in a blender full of water and grind it. After you finish blending ...

Nearly everything at [HAD] is at least based on science in some way or another. If, however, you would like to do some actual scientific experiments with stuff around the house, [Observationsblog] ...

Make an acid-base indicator. Dr Yan uses some very colourful science to find out what's acidic in his kitchen. Take 1/4 red cabbage. Finely slice the cabbage. Put all the chopped-up cabbage into a ...

A well-established technique, acid-base titration is an analytical method used to determine the concentration of an unknown acid or base. In practice, it involves ...

Students will be able to explain that if two substances cause turn a pH indicator different colors, they must be different substances. Students will be able to explain that the color that a substance ...
