9. Complete this PowerPoint or produce a poster on ‘indicators and the pH scale’ You can use this link to get you started but then do your own research as well. http://www.bbc.co.uk/schools/ks3bitesize/science/chemical_material_behaviour/acid s_bases_metals/revise4.shtml Upload your completed work to Moodle by the end of the lesson. pH Scale: The pH Scale states how from how basic to how acidic a substance is. Indicator: Indicators are substances or otherwise known as chemicals that can change colour when added to acidic or alkaline solutions.
