Solubility Of Oxygen

Decent Essays
“Dissolved oxygen is the amount of oxygen that is present in the water” . In order for a substance to be classified as soluble, more than 0.1 g of that substance must dissolve in 100 mL solvent. If this is not satisfied, the substance is said to be insoluble or, more accurately, sparingly soluble. At an air temperature of 25 0 C, the solubility of oxygen is approximately 0.008 g/L , which is equivalent to 0.0008g/100ml, deeming oxygen sparingly soluble. Oxygen gas is a non-polar covalent molecule, and therefore it is not soluble in water as only polar substances dissolve in polar substances. This is due to dipole-dipole bonds forming between two polar molecules. Although oxygen is insoluble, miniscule amounts can be dissolved into water. When a non-polar molecule travels within close vicinity of a polar molecule, a dipole induced dipole is force is formed. When an oxygen molecule approaches the partially negatively charged end of a water molecule, the electrons of the oxygen molecule leave their organised positions and travel to the other end of …show more content…
Ammonia and nitrate are found in fertilisers, which are used essentially on crops. When precipitation occurs, residual fertilisers can be transported into creeks via moving water. When ammonia reaches the creek, it dissolves into the water. This is possible due to ammonia’s ability to form hydrogen bonds. The partially positively charged hydrogen atoms of the water molecule are attracted to the highly electronegative, slightly negatively charged nitrogen atom from the ammonia molecule due to a dipole-dipole force, causing a very strong hydrogen bond . This causes ammonia to be highly soluble in water. Ammonia is toxic to freshwater organisms at concentrations ranging from 0.53 to 22.8 mg/L . Ammonia ions dissolved in the water don’t all continue to be ammonia, and many become oxidised and undergo

    The current problem in Jaffrey is that, recently Jaffrey residents have noticed that Jaffrey Lake, which used to be clean, and a great place to swim, has changed. Slimy, green algae floats on the surface, and the water has turned very dirty. People are finding dead fish on the shore, and everyone is afraid they'll get sick if they swim in the lake. This is a major problem because, people around the lake will slowly start getting sick and one day the all the fish and plants in this water will die because the water is very very dirty. I was hired to test the water to determine the levels of Nitrates and Phosphates in this lake.…

    Why Are Salt Bad

    Salt is used on a daily basis for a number of reasons, such as cooking, water treatment and de-icing roads.[1] In Canada, salt is heavily relied on when it comes to snow removal. But, the truth is, while salt does help people during the winter, it causes the rest of the environment to suffer. Because of this, I strongly feel that salt should NOT be used on our roads. Salt harms animals, affects aquatic ecosystems negatively, causes pollution, contaminates greenery by the road, and damages cars and roads.…

    Minoxidil, an antihypertensive vasodilator medication, which was developed in the 1950’s by a company called Upjohn originally used to treat ulcers. During their experiments with dogs, they figured out that it did not cure ulcers, but acted as a vasodilator. Due to this recent discovery, Upjohn was able to develop a compound called Minoxidil in 1963 as well as being able to synthesize over 200 variations of the compound. The molecular structure and compound of Minoxidil is C9H15N50, made entirely of nonmetals with the molecular weight being 209.2483 g/mol, the UIPAC name being 3 hydroxy, 2 imino, 6 piperidin, 1 ylpyrimidin, and 4 amine. The percentage composition of carbon being 51.65, hydrogen being 7.24, nitrogen being 33.47, and oxygen being 7.64.…

    The greatest human impact on the water quality of Barnegat Bay is irrigation. Irrigation occurs when water is added to land or crops in order to aid in growth. In the northern parts of the bay, where “peak nitrogen levels have been recorded”, many homeowners continually use lawn fertilizers which carry nutrients in the runoff produced (Seitzinger 6). In addition to being a problem in the northern Barnegat Bay area, in the past few years, “the pollution problem is now being magnified by increased development in southern Ocean County, creating the same ecological hazard in the lower part of the bay” (Moore 1). This contributes to nutrient loading, which is when an ecosystem has a high amount of nutrients entering it in a short amount of time.…

    In this lab we will be testing the water quality of the Lewis and Clark Lake. We will be testing to see if the water is good quality and good for the fish and creatures that need that water to live. The first step is to extract the water from the lake and analyze the way it looks. We should write down the description of the water. The second step is to take it to the lab to test the water for pollutants and to test the quality of the water.…

    Less than one percent of all the water on Earth is drinkable to humans. Considering, then, that the Earth itself is about seventy percent water, even less than one percent is still quite a bit of water to work with; however, it does mean that humans are working with a very limited amount of drinkable water. It is very understandable, then, that contamination of that water should be a cause for concern. It has been found that pharmaceuticals are entering the water as pollutant, and there has been subsequent research involving this phenomena. Through several routes, pharmaceuticals are finding their way into water as a pollutant and impacting the ecosystem.…

    Non polar molecules like oils and fats do not dissolve in water but instead stay separate. They do not mix as the non-polar molecule has the electro negativities of the two atoms equal. Dipole- dipole forces are the forces that attract the positive end of a polar molecule to a negative end of another polar molecule. These are the forces that bond the electronegative polar oxygen molecule with the positive polar hydrogen molecule. Dipole-dipole forces account for water being attracted to most substances (adhesion).…
