In the conclusion and evaluation section of your IBDP Chemistry IA, you should summarize the results of your experiment and discuss the overall findings. This section should also include an analysis of any errors that may have occurred during your experiment and ways to improve the experiment in the future. Here is a guide to…
The Winkler Method – Biological Oxygen Demand BOD
The Winkler method is a widely used analytical technique for determining the amount of dissolved oxygen in water samples. Dissolved oxygen is essential for aquatic life and is an important indicator of water quality. The Winkler method involves the addition of reagents to a water sample that react with dissolved oxygen to produce a measurable…
