Physicochemical Properties Of Water Essay
Water is the lifeline of our environment. Our planet earth is dominated by water. Two thirds of earth’s area is covered with water. Scientists estimate that 70% of the earth’s surface is covered with water in the form of oceans starting from Pacific Ocean to Atlantic and Arctic Ocean. This water is not suitable for human use because of the high saline level in the water. The high amounts of salt in saes and oceans require a process of reverse osmosis for make the water fit for human use. The process is a costly one and requires time. The second most abundant source of water is the water stored in the form of ice in glaciers like in Antarctic and Arctic Circles. This water is inaccessible to us and can only be accessed when the ice melts and …show more content…

Physicochemical Properties of Water
Water is one the most important component of our ecosystem. The physicochemical properties of the water are important because these properties play an important role in sustaining the aquatic ecosystem. These properties of the water made water a universal solvent. Some of the properties of water are discussed below:
• Colour: Water is colourless and transparent liquid. Any change in the colour of the water is an indication that water is contaminated. For example, if water is contaminated with decaying vegetation then, the water turns yellow or has a greenish tint in some cases. This is due to the presence of tannic acid which is liberated by the decaying vegetation. The water also turns yellow if it has iron contamination in it. Therefore, colour of water is an important parameter for checking the purity of water.
• Odour: Water is also odourless. It has no smell of its own. But sometimes water can smell bad. This can happen if the water gets contaminated with some microorganisms or it can have a metallic odour if the concentration of metals increases in the water. Municipal corporations use chlorine for disinfection which can also be the cause of odour in the
Gravimetric Analysis Of The % Phosphorous In Miracle Gro
687 Words | 3 PagesThere may have been some other contaminations in the funnel or filter paper that contributed to this color. Possibly, there might been some precipitate in the precipitation flask, but was not rinse with acetone and re-filter due to lack of time. For future practices, DI water should be added at reasonable proportions and not too much on precipitate that won’t wash out. This will make the vacuum filtration a quicker process by avoiding large volume of filtrate. Moreover, the filter paper should be replaced after a new vacuum
Unknown White Compound
577 Words | 3 PagesMany unknown micro-contaminants are present in water. Some of the micro-contaminations might pose a risk to drinking water and human health. In many countries, surface water is one of the main sources of drinking water. The quality of the drinking water is influenced by many factors, such as agricultural and industrial waste, and is monitored regularly. Stated by the Journal of Chromatography, there are many techniques such as gas and liquid chromatography in order to detect the pollutants.

1455 Words | 6 PagesDissolved Oxygen is another thing we tested for, that 's how much oxygen gets mixed within the water ( Ex. rapids - the white part of the rapids is the oxygen mixing with the water- .) We also tested how fast the water was moving or the ( speed/velocity. ) We were going to test it by using a bamboo pole with a string ( with a certain length ) and a bobber on the end and see how long it takes for the bobber ( from its full length ) to hit the bamboo pole. To find the actual speed of the water you take the length of the string divided by the time ( sec/centi
Water Simulation Lab Report
407 Words | 2 PagesThis lab uses a lake simulation to study how the addition of nutrients and toxins can affect the lake, its inhabitants and the surrounding area. There is a strong focus on the addition of Phosphorous and added toxins because both are key elements in growth in lakes. The Virtual lake includes these five simulated species; green algae, cyanobacteria, bosmina, daphnia, and trout. There are two types of phytoplankton in the lake model, green algae and cyanobacteria. Green algae are a very diverse group that are photosynthetic, aquatic, plant like organisms that have a very simple reproductive structure.

The Importance Of Water In Sacramento River, California
125 Words | 1 PagesCalifornia needs a lot of water, since it is one of the top agricultural state. As, water accessibility states choices for “crops and irrigation” approaches. Since, most of the water that is utilized by agriculture goes to five main produces like:” alfalfa, cotton, rice, grapes, and irrigated pasture”. Most water is received from the Sacramento River, Colorado River, as the San Joaquin River. However, all these rivers carry a quite a lot of salt and with climate change happening is creating tings worst.
Role Of Desalination In California
1275 Words | 6 PagesThe First solution is desalination which is the process of removing salt from the sea water to make it drinkable water. Have you ever thought that it would be great if we can use the water from the sea? Because no matter how weather has changed, there is always huge amount and unlimited water in the sea, and we all can use it. The only reason why we cannot use that water is because it is salty water. Desalination can help to make our dream possible.
Essay On Soda Water Titration
1337 Words | 6 PagesResearch Question: To investigate and compare how different temperature (5℃, 15℃, 25℃, 35℃, 45℃) can affect the concentration of carbon dioxide in soda water through titration with sodium hydroxide solution. Introduction: Carbon dioxide plays an important role in soft drinks. Soda water is manufactured by pumping carbon dioxide into water under high pressure. Carbon dioxide dissolves in water to form carbonic acid, which is the fizz we find in soft drinks. CO2 + H2O ⇌
Essay On Water Hydrophobicity
1964 Words | 8 Pages. SUPER HYDROPHOBICITY Soumya Ranjan Sahoo (711CH1025) NIT, Rourkela Abstract: Superhydrophobicity as a sensation has turned into an increasing focus of research and technological movement, where its key viewpoints span surface chemistry, chemical physics, and cellular biology. Hydrophobic particles have a tendency to be non-polar and, accordingly, incline toward other neutral molecule and non-polar solvents. Hydrophobic atoms in water frequently bunch together, shaping micelles.

Essay On Solubility
1230 Words | 5 PagesSolubility of a Salt Introduction: The solubility of a pure substance in a particular solvent is the quantity of that substance that will dissolve in a given amount of a solvent. Solubility varies with the temperature of the solvent. Thus, solubility must be expressed as quantity of solute per quantity of solvent at a specific temperature. For most ionic solids, especially salts, and water, solubility varies directly with the temperature.
