Several theories have been developed to explain the behaviour of acids and bases. The most notable theories include the Arrhenius concept, the Brønsted-Lowry theory, and the Lewis concept. In the ...

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 ...

Many chemicals can be classified as being acidic, neutral or alkaline by using indicators. The pH scale is used to measure acidity and alkalinity. When an acid is neutralised, it forms a salt. Making ...
