• Measure pH and perform and interpret chemical tests on water samples
• Identify common pollutants in natural waters and gain a basic understanding of water analysis
• Understand and appreciate the relationship of chemicals in the environment
• Science learning kit for intermediate and junior high science courses
• Good for up to 50 students

Students use safe, easy-to-perform chemical tests to analyze water samples for the common pollutants: ammonia, cyanide, silica, chlorine, iron, sulfide, chromium, nitrate, copper, and phosphate. Pollutants are detected through color changes - the deeper the color, the greater the pollution. The semi-quantitative results are accurate, reliable, and very dramatic. This kit provides an effective way to examine a region's natural and treated waters which often contain contaminants from sources such as sewage, industrial chemicals, air pollution, fertilizers/ pesticides .Kit includes Teacher's guide with MSDS , student worksheets and guides , Lab-aids chemplates with spatulas , calibrated sample tubes with caps , bottle of chromate indicator powder , bottles of iron indicator powder no. 2 , bottles of nitrate indicator powder no. 2 , drop control bottles of nitrate test soln. no. 1 , drop control bottle of ammonia test soln. no. 1 , drop control bottles of ammonia test soln. no. 2 , drop control bottle of chlorine test soln. drop control bottle of chromium extracting solution , drop control bottles of phosphate test soln. no. 1 , drop control bottle of phosphate test soln. no. 2 , drop control bottle of silica test soln. no 1 , drop control bottle of silica test soln. no 2 , drop control bottle of silica test soln. no 3 , drop control bottle of silica test soln. no 4 , drop control bottles of sulfide test soln. 1 , drop control bottle of sulfide test soln. 2 , drop control bottle of sulfide test soln. 3 , drop control bottle of universal indicator , drop control bottle of copper test soln. no. 1 , drop control bottle of copper test soln. no. 2 , drop control bottle of cyanide test soln. no. 1 , drop control bottle of cyanide test soln. no. 2 , drop control bottle of iron test soln. no. 1 .
