Lab-Aids Qualitative Introduction to Water Pollution Kit 19

Description

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 (often from agricultural or recreational areas such as golf courses).Kit includes Teacher’s guide with MSDS (1), student worksheets and guides (50), Lab-aids chemplates with spatulas (12), calibrated sample tubes with caps (12), bottle of chromate indicator powder (1), bottles of iron indicator powder no. 2 (2), bottles of nitrate indicator powder no. 2 (2), drop control bottles of nitrate test soln. no. 1 (2), drop control bottle of ammonia test soln. no. 1 (2), drop control bottles of ammonia test soln. no. 2 (1), drop control bottle of chlorine test soln.
