Turbidity is the measure of the clarity of the liquid. It is a visual characteristic of water. It causes the water to turn cloudy or opaque. Clay, silt, algae, divided inorganic and organic matter soluble colored organic compounds, and many other components will cause water to become turbid. In order to measure turbidity, a light is shown through the water and is measured in nephelometric turbidity units. A large amount of turbidity in the body of water affects light penetration and productivity in the water. Plus, lakes with a high concentration of turbidity can cause the lake to fill in faster. When water is very cloudy, it can be a sign for health concerns. Turbid water can be used as food and shelter for bacteria and pathogens, which, if not fixed, can cause water-born diseases. Water treatment plants have the ability to clean the water of turbidity properly and that …show more content…
The term hard water means that there is a large amount of dissolved calcium and magnesium. This causes a film of residue on your hands after you wash your hands with soap. Plus, it is the reason for the spots on glass cups that were in the dishwasher. If you use hard water, it takes more soap or detergent to get things clean. Hard water can actually be a good thing as well. Drinking hard water can contribute to a small amount of calcium and magnesium to the dietary needs of a human. It is measured by milligrams per liter. Soft is ranged from 0 to 60 mg/L, moderately hard is from 61 to 120 mg/L, 121 to 180 mg/L is hard, and 181 and higher is very hard. When water moves through rock and soil, it dissolves very small amounts of minerals and they then flow into the groundwater supply. This is a major concern for water systems that use groundwater as a source. Since water hardness varies on the location, industries have to adapt to it by making the water they use softer because it can cause damage to the equipment they
C.E 1.3 First, I made exhaustive investigation of the actual significance of the work. I found that the water film thickness detection was an important means to avoid friction and abrasion and avoid the original working performance and service life. For example, in
This low amount of dissolved solids makes the lake 's water, void of any other consideration, an ideal drinking
To test turbidity, take the tube and put the water in the tube and see if you can see through the tube. If the levels of the tests were normal and good, that would mean the river is
Dissolved 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
When concerning our drinking water it should be considered that pathogenic organisms may contaminate soil, as well as stick on to the sediments in the surrounding area; making it more tricky to clear completely. Nitrate poisoning is another large concern,
Drinking contaminated water can cause different types of cancers and also infertility and birth defects due to of the presence hazardous chemicals. Impoundments that have not been built or properly closed off have led to the death of many animals and also health issues in
Summer Reading Essay: The Color of Water James McBride turned out to be a very good man although his outside influences growing up would encourage the opposite. Growing up with more than one father figure in his life and many older brothers and sisters sent his life spiraling out of control but eventually came to a calm and quiet hault. A father is someone who is supposed to teach his son to be a man; not every man has the same beliefs or teaching, so having many different views in and out James’ life was probably hard to balance. The many men that took on the role of his father as he went through life had major effects on him and made him who he is today.
The Color of Water, by James McBride, is about his journey to find who his mother is and who he is. It talked about problems between different races and between jews and society. Many of the events that the characters went through are relatable and heart breaking. The Color of Water is a heart-touching story.
Exploration Title: Effect of Temperature on rate of Osmosis Submitted By: Abdulkarim Kamal Date Submitted: October 19th 2015 Subject: Biology HL Teacher: Mr. Nick Aim: This is an investigation to determine the relation between temperature of a solution (sucrose) and the rate of osmosis Scientific Context: Osmosis is defined a passive transport process in which a fluid diffuses across a semi-permeable membrane, from an area of high solute concentration to an area of low solute concentration and vice-versa. There are various factors that could potentially influence the rate of osmosis; these factors include volume, concentration, and temperature. If all external factors that may interfere with rate of osmosis are controlled, the results will show equal amounts of fluid on both sides of the barrier (membrane); this is known as an “isotonic” state.
I’ve never had to think about chemistry being connected to our society, but almost everything is chemistry related; for example, the soaps we use to wash our hands are made up of potassium salts of fatty acids. The process to make soap is called saponification, which involves heating fats and oils and reacting them with a liquid alkali. When the alkali is sodium hydroxide, hard soap is formed “bar soap” and when the alkali is potassium hydroxide, a potassium soap is formed “liquid soap”. A question I have about soap is... If the effectiveness of soap is reduced when used in hard water, why is it that many health care settings have hard water?
Eutrophication, which is excessive richness of nutrients in any form of body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen, is another reason why the creek could be polluted. Fertilizers are used in farming to provide crops with nutrients, but they also play a big role in the Eutrophication process. If too much fertilizer is used, it leaches from the soil in
This information proves that soapy water’s surface tension breaks faster, and causes the hydrogen molecules to break faster as well. Adding soap to water makes its surface tension decrease, so soapy water drops become weaker and break apart faster. This stops water molecules from adhering to each other, this lack of adhesion is what allows soap to clean dishes and clothes more easily. I believe that one error or variable that isn’t accounted for in this experiment is the lack of consistency in each droplet of water, some drops may be very large while other might be miniscule. This variable, while it doesn’t seem like a big ordeal, can deeply affect the outcome of this experiment.
This means that 25 to 40 percent of the bottled water is not any different from the tap water only that it has been exposed to or has a high concentration of the chemicals used to manufacture the packaging plastics. Due to the pathetically primitive regulation of the bottled water, the manufacturers are not keen to inform the consumers of the contaminants that are present in their water. According to Warburton (1993), consumers are likely to drink bottled water containing contaminants such as E.coli, asbestos, giardia, bromate and many other industrial chemicals and pathogens. Arnold & Larsen (2006) indicate that ten water brands in the US had thirty-eight
Desalination Essay Introduction: Drinking seawater is bad, the salt makes you dehydrated and the more salt water you drink the more it makes you sweat. You also get a dry mouth and low blood pressure as well as your heartbeats faster; you could get bad headaches and a lot of dizziness. Most of the biggest desalination plants are in the middle east like United Arab Emirates, Saudi Arabia, Israel and many more, but the biggest desalination plant in United Arab Emirates it is the biggest power production, in Jebel Ali M-station in Dubai. The plant has an installed capacity of 2,060MW (mega watts) and 140 million imperial gallons of water per day.
The overall project goals and central questions that has to do with the project is mostly trying to determine the isotonic concentration of the salt in potato roots and the use of the ideal soil salt conditions for the potato plant growth. In part 2, we had to test the enzyme activity that is in the was involved in the potato, so we can also determine the ideal soil pH conditions for the potato plant growth. In part 3, we were able to test absorb the leaf pigment at various wavelengths that determine the optimum light absorption conditions and was able to make recommendations for the light conditions that would be used un greenhouses. The goal of the first project is to determine the ideal soil salt for potato roots and we can relate this to the project is to find out if Solution A or Solution B has more solute in it. The goal of this project is to determine the meaning of Osmosis.
