Solution
The COD (Chemical Oxygen Demand) test is a measure of the amount of oxygen that can be consumed by chemical reactions in a measured volume of water. It is commonly used to assess the quality of water and the effect of discharges on the environment.
During the COD test, a strong oxidizing agent is typically used to oxidize the organic material in the sample. The oxidant used in the COD test is usually potassium dichromate (K₂Cr₂O₇), which is considered a very strong oxidizing agent.
Answer
