What is Winkler Method for Dissolved Oxygen about?
The document discusses the Winkler method for measuring dissolved oxygen in water samples. It explains that (1) oxygen is needed by aquatic plants and animals and its lack can kill them, (2) the Winkler method involves titrating iodine produced from a water sample with sodium thiosulfate to determine the oxygen level. Special modifications using sodium azide are needed when nitrites are present to avoid interference. Measuring dissolved oxygen through the Winkler method is an important water quality test.
