What is the Winkler Chemical Method?
For a field study of a lake's water quality, I tested dissolved oxygen levels using a test kit from Hach, which uses a modified version of the Winkler Chemical Method. Can anybody tell me what exactly is the Winkler Chemical Method?
It is a double indicator titration that usually involves the use the BaCl2 or Ba(OH)2.
