Nitrogen is a nutrient, water, nitrogen in the water, if there is too much to do, the water becomes wastewater. Because when you have a lot of nutrients, it may make them water-weed, water plants. Plant platform blank now more growth, which in effect makes the oxygen in the water decreases. Make the water becomes polluted water was broken. Therefore we need video khrao quantity of nitrogen in the water that the water source is the quantity of nitrogen contained in the criteria that would make the water becomes polluted water?In the trial process. We measure the quantity of nitrogen by using distillation and titration. We prepared sample bottles, 500 ml each, 5 bottle first is distilled water bottle is put distilled water until the volume is the third bottle was put into a bottle of distilled water until the fourth and fifth volume is water from a water source area, Department of chemical engineering at filtering out sediments (solid), we need to adjust the volume of the sample is then taken by the entire sample bottle to bottle, each to be.
