Examination of Water and Wastewater 5210 BIOCHEMICAL OXYGEN DEMAND (BOD)*#(1) 5220 CHEMICAL OXYGEN DEMAND (COD)*#(2) 5220 A. Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties‚ the dichromate ion (Cr2O72–) is the specified oxidant in Methods Section 5220B‚ Section

Abstract: The objective of Experiment 1 was to observe some chemical changes. While observing the chemical changes in elements I also experimented with household cleaners to see how much chemical properties relate to our daily lives. Chemical changes occur all around me and I go without noticing them all the time without a second thought. This experiment opens my eyes to different chemical reactions occurring around me. This experiment also shows the importance of dilution. If I did not dilute something

world today at our global civilization there are many problems that leap to our attention and everyone has a vested interest‚ one such example is food. Science has been tinkering with nature for the past one-hundred years trying to come up with solutions to help fight famine‚ and as a result‚ man made products have created ever more problems. The easiest way in which an individual or individuals can create change is to effect change in their local communities‚ so others can see an image of what the
