pH scale
-
The pH scale is a scale from 1-14 that measures how acidic or alkaline a chemical or substance is. 7 is neutral, 1-6 is acidic and 8-14 is alkaline. Depending on what it is, it turns a different colour when universal indicator is added to it. If it's an acid it turns red-yellow, if it's alkaline it turns blue-purple and if it's neutral it turns green
You can make your own indicator by crushing red cabbage with a pestle and mortar and adding boiling water.
