Which contaminant seemed to have the most potent effect on the water? The effects of the contaminated water were that the mixture showed each water type to have a brown color to them. The water type that seemed to have both a surprising and potent effect was the water and soil mixture. I would have thought with using strictly water and potting soil the water turned the darkest brown out of all the other contaminants that I used for the mixture. The vinegar and soil mixture seemed to have cleaner look to them.
Alkalinity can be defined as the capacity to neutralize acids. Carbonates (CO32-) are a major constituent in natural water that helps it behave as a buffer. Acid rain can reduce the alkalinity of water and hence would decrease its pH. In this experiment, water sources that measure pH below 5.6 will be considered acidic precipitation. Water from a variety of sources that receive precipitation is being sampled.
Identify the processes (e.g., coagulation) that were used in this lab and describe how they were performed. You start out with the contaminated water that has not been filtered out or has not had any chemicals added to it, this is many done so air can meet the water and this gives the chemicals and gases to release. I then added Alum to the dirty water since when mixing Alum with the dirty water it allows all the big particles to “stick” to the Alum and then pushes all of these particles to the bottom of the water. The dirty water is then put through a filter of sand, charcoal, and gravel in order for any of the smaller particles to stick to them and makes the water clean and free of any other particle. After I did all this I then had to add a few drops of bleach so I could disinfect the water from any other dirt
Vinegar, Antacid, and Soap all became positive solutions after I put in the enzyme. A change in pH disrupts an enzyme's shape and structure. pH measure acidity--water is neutral and has a pH of 7. When the pH changes an enzyme's structure, the enzyme can't do its job. Changes in pH break the delicate bonds that maintain an enzyme's shape.
Vegetable oil is hydrophobic and there for is not water soluble but alcohol on the other hand is completely soluble with vegetable oil. 3. We know from observing the vegetable oil and water together that the relative density of water is greater then the density of vegetable oil because the oil will always recede to the surface of water. 4. Emulsification agents allow for two unbendable liquids to be combined, the detergent hold properties that both substances can in return blend with leaving detergent dissolving in both the water as well as the alcohol unlike other substances we tried to
Acid Rain – Part 1 Amber Williamson Kaplan University Acid rain is a term referring to a mixture sulfur dioxide and nitrogen in the atmosphere with wet weather that form rain. This flow of water affects a variety of plants and animals, depending on the strength of the acid in the water; the chemistry and buffering capacity ---the ability of substance counter variations in pH. Analysis of Subjects Cup | Color |Length of Stem |# of Leaves |Roots present |# of main roots |Length of roots | |Tap Water |Dark Brown |6 inches |72 leaves |None |0 main roots |0 inches | |Bottled Water |Dark Brown |6 inches |72 leaves |None |0 main roots |0 inches | |Acid Water |Dark Brown |6 inches |72 leaves |None |0 main roots |0 inches | | Hypotheses The tool used to measure acid in rain is a pH, pure water is a pH level of 7.0 and typical rain measures with a pH of 5.6. I am using rosemary as my plant for my number 1 experiment. I am having some difficulties as my plant does not look health but rosemary does regenerate.
Pollution in seasonal wetlands Wetlands are considered habitats that help trap and reduce pollutants that come from all types of sources, such as oils from cars, chemicals from drainage runoff, sprinklers that have fertilizer runoff from nearby grass located around buildings, agriculture runoff, untreated sewage from pets and human waste, and in flow of domestic and industrial wastes. Other harmful chemicals that are human related are antibiotics from animal husbandry, pesticides that act as endocrine disrupters. (Ramsar 2008) These pollution sources all contribute to the negative health of wetlands all over California. Roseville wetlands are being inundated with water pollution from many of these human related sources around them. Wetlands can only handle so much of these pollutants, and with the major habitat loss that has completely changed the dynamics of these once seasonal wetlands, can only limit the ability for these wetlands to filter as much of the pollution as possible.
People may contract serious illnesses or even worse, die from drinking contaminated water. Body Paragraph # 3 - Hypotheses: If oil is dumped on the ground, then the groundwater below will not contain traces of oil. If vinegar is dumped on the ground, then the groundwater below will be contaminated with vinegar. If laundry detergent is dumped on the ground, then the groundwater below will be contaminated with laundry detergent. If water mixed with soil is passed through a filtration system, then it will emerge free of soil.
Reason being if someone was upset they could do something wrong by not paying attention, or if someone is angry they could be careless and put too much dye into a glass. Title: The effect of salt concentration on osmosis in potato. Introduction: The purpose of doing this lab was to observe the effects that when salt is added to water in different strengths, what the effect do to the cells. Osmosis is the diffusion of water
Clay held 93.8ml of gas, 146.2ml of oil, and 104.5ml of turpentine. For the most part our experiment followed the hypothesis. The higher porosity soil held more than sand, but since clay had such small pore spaces between the particles it held most of the pollution on top not allowing it to seep through and therefore doesn’t have the highest porosity but still held the most pollutants. INTRODUCTION Soil contamination is the invasive presence of man-made chemicals or other alteration in the natural soil’s environment. Most soil pollution comes from the use of pesticides, underground storage tanks, and the intended release of chemicals from industrial companies.
