To determine how much alkalinity a sample contains using a colourimetric method. Testing will be done on a Local Community Treated Water sample; the teacher will do this as a demonstration.
There is no Canadian Drinking Water Guideline for Alkalinity in drinking water, but it is an important characteristic of the water and if your local community water is less than the LLS then the water may be quite corrosive, which may result in increased levels of copper and lead leached out from household plumbing.
