How Do You Calculate Dissolved Oxygen In Water?
Water typically contains a certain amount of oxygen gas dissolved in it. You can measure the concentration of dissolved oxygen in a sample of water with a procedure known as the Winkler method. This method is commonly performed to estimate the concentration of organisms that a body of water can support. The reagents needed to perform the Winkler test are available in a kit from scientific supply stores. Fill the bottle to the line with the water sample. Use a pipette to add two milliliters (ml) of manganese sulfate below the water’s surface so that you don’t add air bubbles to the water. Add two ml of alkali-iodide-azide in the same way. Place the stopper in the bottle and ensure that there’s no air in it. Mix the reagents by turning the bottle upside down several times and wait for the orange solid to settle to the bottom of the bottle. Pull the stopper out and add two ml of Sulfuric Acid below the surface of the water with the pipette. Put the stopper back in and turn the bottle upsi
