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] ...

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 ...

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 ...

* Found with the antacids in most grocery stores and drugstores. † Make red cabbage indicator: Shred 1-2 red cabbage leaves and freeze 1 hour in a zip-close plastic bag. Add 1/3 cup warm water, reseal ...

Acids and bases are classes of materials that have different properties. Acid-base indicators change color depending on whether they are in acids or bases. Many berry juices contain a substance called ...

The answer is straightforward: phenolphthalein turns colorless in an acidic solution. When the pH of the solution is below 8.3, the indicator remains in its non-ionized form, which does not absorb ...

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 ...

I’m sure many of you reading this can remember your first acid-base titrations in chemistry class—the thrill of watching the pH indicator change color, and the fear of opening the stopper too much and ...
