Description
By performing simple colorimetric chemical analyses, students examine water samples for the presence of a wide variety of possible contaminants. Although the testing procedures are simple and straightforward, the results are reliable and dramatic. Natural and treated water samples are tested for ammonia, chlorine, chromium, copper, cyanide, iron, nitrate phosphate, silica, sulfide, and pH. Enough material is provided for 50 repetitions of each of the factors tested. Kit includes all necessary labware and supplies; 50 student worksheets/guides; and teacher’s manual with MSDS.
