A Crash Course in Acids and Alkalines

We all crowded around the table as the instructor prepared the experiment. He blended cabbage juice to use a makeshift pH indicator.

Working with Chemicals

We were divided into groups and tested the pH of house hold chemicals. Lemon Juice, Vinegar, Liquid soap, Soda Water, Bicarbonate of Soda and Diluted ammonia.


6C learned a lot during the Chemical Opposites course, about Acids and Alkalines and everyday chemicals. We enjoyed the course thouroghly and would recommend it to other classes.
