Biochemical oxygen demand (BOD). Such chemicals are also liable to be broken down using strong oxidizing agents and these chemical reactions create what is measured in the laboratory as the Chemical oxygen demand (COD). Both the BOD and COD tests are a measure of the relative oxygen-depletion effect of a waste contaminant. Both have been widely adopted as a measure of pollution effect. The BOD test measures the oxygen demand of biodegradable pollutants whereas the COD test measures the oxygen demand of oxidizable

Observation of Chemical Changes Purpose In this experiment‚ the student studied the composition of materials in a setting where the indications of chemical changes were safely observed. The changes observed consisted of bubble formation‚ colors‚ viscosity‚ and precipitate formation. Procedure Using a well plate: use a different well for each chemical combination. Two drops (unless otherwise noted) of each chemical in the combinations (below) should be placed in one well. A dark and light

the order process it is important to have the correct information provided in a timely fashion to all divisions. For integration to be successful information must be available throughout the entire supply chain. The main problem is with Woodson Chemical Company is the lack of management and communication across all divisions within the organization creating bottlenecks throughout the operations. There are several sub problems seen throughout the organization at different levels of management and

CHEMICAL ATTACK ON SYRIA Over 110‚000 people have died in Syria since the beginning of a years-long conflict in the country. On August the 21st‚ the U.S government says that 1‚429 died through the chemical attacks which marked the sea change in foreign policy towards the Middle Eastern country. The impact of poison gas is horrific and fatal. Those exposed to the nerve agent can die within 15 minutes of exposure.

Name: Jayanti Magar Title: Observations of Chemical Changes Date: 02/11/015 Pre Lab Questions: Use what you learned in this lab to answer the following questions. A. Suppose a household product label says it contains sodium hydrogen carbonate (sodium bicarbonate). How would you test this material for the presence of sodium bicarbonate? I would add hydrochloric acid (HCl) with carbon dioxide with NaHCO3‚ and it should bubble and form gas. B. You know what color phenolphthalein and bromothymol
