Objective: To discover the pH scale and why it is used by scientists
Introduction: The quality of our drinking water is tested all over Canada. Each community has a water treatment plant where employers conduct a variety of tests to ensure that our drinking water is clear and safe to drink. Contaminated water can pose a number of risks to our health, and it is important we ensure the safety of drinking water and obtain water testing that meets all regulator requirements and quality standards in Canada. One of the tests that are done at local water treatment plant is the pH test. A simple pH test determines the acidity of the water, with the goal of it being as close to neutral as possible. A neutral pH ensures that the water is safe to travel through pipes (minimizes corrosion) and to drink.
Curriculum Connections: • Students will conduct investigations into relationships among observable variables and use a broad range of tools and technique to gather and record data. • Students will compare changes in pH with changes in concentration for acids and bases
