Why use starch solution in winkler method?
Starch solution is used in the Winkler method to act as an indicator for the presence of oxygen. When titrating the sample with iodine, the starch solution forms a blue-black complex with the iodine in the presence of oxygen, providing a visual endpoint for the titration. This helps to accurately determine the amount of dissolved oxygen in the sample.

What is winklers reagent?
Winkler's reagent is a solution used in the Winkler titration method to measure the concentration of dissolved oxygen in water. It consists of a mixture of manganese(II) sulfate, alkaline iodide-azide solution, and sulfuric acid. When added to a water sample, it reacts with dissolved oxygen to form a colored complex, allowing for quantification through titration. This method is commonly used in aquatic studies to assess water quality and ecosystem health.
