As aquatic photosynthesis is light dependent, the dissolved oxygen produced will peak during daylight hours and decline at night. 2. The potability or “drinkability” of tap water varies from place to place. The distillation process ensures that contaminants are left in the boiling vessel, which results in a cleaner and more pure water in the collection vessel. 3. The stable form of oxygen in the Winkler Titration Method in determining the dissolved oxygen in water was magnesium dioxide. The free iodine in the Winkler Titration Method turned the solution into a red color. 4. Tap water is more pure than distilled water. The purity and cleanliness of distilled water remains constant no matter where you get it…
