Acids and Bases – Year 8 Science

Today we will be doing an experiment with acids and bases – making a pH indicator using red cabbage and testing various household substances. PH is a measure of the acidity (ph is less than 7) or alkalinity (ph is greater than 7) of a substance.

Here is a similar experiment to the one in your textbook. Acids and bases from Vision Learning, includes a colour chart and pH of various substances. Good information from Chemistry 4 kids here.
