What is Dissolved Oxygen Analysis in Water Samples about?

This document describes an experiment conducted by students to analyze dissolved oxygen in water samples using the Winkler method. The students first collected a water sample, avoiding aeration. They then added reagents - manganese sulfate, alkaline iodide, and sulfuric acid - to fix the sample. The fixed sample was then titrated with sodium thiosulfate until the solution lost its color, allowing the dissolved oxygen content in mg/L to be determined based on the amount of titrant used. The document provides
