That dissolved oxygen is employed by the aquatic organisms for respiration. The heterotrophic microorganisms current within the water also uses the dissolved oxygen.
The Winkler Technique employs titration to determine dissolved oxygen during the water sample. A sample bottle is loaded totally with water (no air is still left to skew the outcome). The dissolved oxygen in the sample is then "fastened" by including a number of reagents that kind an acid compound which is then titrated using a neutralizing compound that leads to check here a colour change.
