Activated Charcoal Filter Case Study

Equipment- 250mL beaker, 125mL Erlenmeyer flask, cardboard square, chemical scoop, metric ruler, lab countertop, rubber stoppers, safety goggles, lab apron

The materials that were used to carry out the experiments on the water samples were ten testing kits. We ran 10 tests on all

The materials that were used/needed in this experiment were a penny, water, soap, rubbing alcohol, a pipet, and a beaker.

In this report, we will be analyzing the current performance of Kingsford in the marketplace and identify the main cause of revenue deterioration. Thereafter, a comprehensive strategy and marketing plan will be presented.

The materials needed for this experiment included test tubes, a test tube holder, the unknown compound #202, 35mL beakers, gloves, safety goggles, ethanol (to clean equipment), stirrer (to mix solutions), the 15 possible compounds that are provided, pH strips, distilled water, wooden splints, spatula to get out unknown compound #202, waste bucket, Bunsen burner, graduated cylinder, 500mL beaker for the waste, plastic dishes to measure out compound and the scale.

Our objective for the Sherlock Holmes Experiment was to illustrate that some chemicals can be identified or differentiated by simple chemical tests, such as solubility, pH, or color tests. In our group we had to test come common powders such as Alka-Seltzer, baking soda, flour, Vitamin C (ascorbic acid), and salt. Other chemicals that were used to do this experiment were vinegar, and Iodine 2 Solution. The equipment used to do this experiment was red litmus paper, and 5 test tubes per group.

The more polluted a water source is, the more processing required to make the water safe to drink. Most of the contaminants now in Flint’s drinking water were introduced during or after processing. For all drinking water, the first concern is bacteria, which can cause diseases like hepatitis, Legionnaire’s disease, and other illnesses. Because Flint’s river water had high levels of bacteria, it was treated with additional chlorine. Chlorine reacts with organic material in the water to produce carcinogenic byproducts such as trihalomethanes; it also makes water more acidic, which corrodes pipes. Federal law mandates adding anti-corrosive agents to drinking water in large cities; this standard water treatment practice was not followed (Carmody, 2016). The water created issues with lead due to its high acidity. Water service connections have been made for years using lead piping primarily in the 1920s and 1930s. The acidic water corroded the old lead pipes and lead seeped into the water. Lead poisoning is the most widespread and serious health problem associated with Flint’s drinking water; children with prolonged exposure to lead experience a range of developmental problems that are incurable. Flint’s water-treatment staff were not able to successfully make Flint River water safe to drink. Whether this is because they were undertrained, understaffed, or simply made a decision not to invest scarce

In the article “It’s All Just Poison Now”, Oliver Laughland and Ryan Felton discuss how the lives of the residents of Flint, Michigan have been negatively affected by the city’s tainted water supply. Flint’s aging lead pipes, coupled with its corrosive water sources, have cause a number of contaminants to seep into the water supply. On top of this, the city’s water supply is inadequately purified, which caused many residents to be exposed to these toxins. The main concern to residents is the presence of poisonous lead in the water, which can be deadly even in low amounts. The community of Flint has been unknowingly drinking and bathing in these chemicals, despite being told by city officials that the water was safe. As a result, many residents

An essential necessity for life is slowly killing residents in Michigan. The town of Flint, Michigan is slowly being poisoned by their water supply. Flint is 70 miles north of Detroit with a population of 98,310. According to the U.S. Census Bureau a little under half of residents live below the poverty line. More than fifty-five percent of the city’s population is African-American (CNN Library). The dangerous lead levels in the water went unnoticed for years, despite the residents’ complaints of discolored and foul-smelling water. The question at hand is how could this happen?

In consuming the water, the children, as of 2015, are consuming 3 times the amount of lead compared to 2013 (source)

The lead effects in the drinking water have caused a massive public health crisis (“Scientific Opinion on the risks”, 2015). The whole crisis was as a result of poor management practices employed in the Flint water plant. The city decided to switch the

During the lab we had to use lab tubes, a pipette, beakers, safety goggles, gloves, oven top, beaker tongs, water,

Children started loosing their hair or developing rashes on their bodies. According to Mark Peplow, lead “levels of around 400µg/l” (1 microgram per Liter or 1.0 × 10-6 kg per m3) were found in some residents’ tap water (Peplow 4). This, of course, prompted the intervention of the Virginia Tech research team. Peplow continues, “In September 2015, pediatrician Mona Hanna-Attisha of Michigan State University analysed [sic] the results of infant blood tests, and found that the proportion of children with elevated lead levels in Flint had doubled from 2% to 4.1% since the change in water supply. After a week of denials, the state admitted that her analysis was

The materials used during the experiment included three plastic cups, three gummy bears, masking tape, marker, balance, calculator, tray, one plastic spoon, a measurement tray, and a ruler. The three plastic cups were used to hold the tap water, salt water, and sugar water. The masking tape and marker were used to label each cup with the

Overall, the results mainly do support the original hypothesis. Throughout the 8 days of experiment, there was no lead, bacteria, or sodium detected by the test kits or the test strips that were used in any of the waters of the water bottle brands and tap water in both environments thus proving the hypothesis that was originally posed, correct. This was the same for the tap water from Quincy, Massachusetts in both environments, thus not supporting the original hypothesis of the belief of traces of lead or bacteria in the tap water of Quincy. However, the original pH estimates for the different types of water were not correct. The hypothesis about how pH balance would decrease in the cooler environment and increase in the warmer environment
