The pH of different liquids before and after they are filtered Problem Does filtering different liquids cause the pH to change? Hypothesis: The pH of the dirty water and the salt/bicarb soda/sugar water will change the most drastically when they are filtered. Aim: To investigate the effectiveness of a natural water filter on the pH of different liquids. Materials: • Green Science Clean Water Kit (includes plastic filter system, active carbon, sand, rocks, and filter paper) • pH Indicator strips • Liquid measuring cup • Bowls (x3) • 1 Teaspoon measurement • 1 Tablespoon measurement • Plastic cups; clear (15~ 2 for each of the 6 liquids and 1 for a comparison water sample) • Small bowl of garden dirt • 2 tablespoons of salt (table/rock …show more content…
Make a contaminated water sample: Using a clean plastic spoon, mix 1 cup of water in a small bowl with garden dirt. Add ¼ teaspoon of vegetable oil with a medicine dropper to the water mixture, approximately 4-6 drops. Mix the oil and the dirt together until everything is combined into the water. Pour the dirty water into a clear plastic cup. 4. Test the pH of the contaminated water using pH indicator strips. Record the pH of the water sample and then begin the filtering …show more content…
Carefully place the filter column on top of another clear plastic cup. Slowly pour half of the water mixture into the filter. The water should move between each section of the filter drop by drop. Meanwhile, continue to mix the contaminated sample with a spoon so the dirty doesn’t settle at the bottom. 6. Once the contaminated water is filtered retest the pH of the water and compare the pH of the contaminated water to the pH of the filtered water. You should also record any other observations that you make about the filtered water. For example, if the filtered water has any grit or dirt still visible in it. 7. Boil 1 cup of water in an electric kettle. Place the teabag in the mug and pour the cup of boiling water into the mug and let it sit for 15 minutes (timed) undisturbed. Remove and discard the tea bag and let the tea cool down as you proceed with the following steps. 8. (Maybe talk about taking filter apart and rinsing) 9. Place 1 cup of powerade in a clear plastic cup. Test the pH of the sports drink using pH indicator strips. Carefully place the filter on top of a clean, clear plastic cup. Slowly pour half of the sports drink into the filter, and watch as it moves between the filter drop by
For this experiment, there is several materials needed to have a successful lab experiment. This includes the basic utensils such as the datasheets, pencil, and a notepad to add additional notes. Following the list of materials, you will need three bottles to collect sampling water
When I tried to filtrate the water to remove the contaminants, I am not completely successful because the water is not 100% contaminant free since the water has a rancid smell.
When the water is so contaminated that you cannot drink it, what could you do to get a pure glass of H2O? Students taking Western Kentucky University (WKU) Dual-Credit “SPAN Chemistry” class at Metcalfe County High School (MCHS) completed a lab investigation of the distillation of contaminated water.
The Cucamonga Valley water district has a water treatment plant. The treatment plant tests the water to make sure it is safe for the public to drink. The water is tested by going through a series of multiple test/treatment processes. You have to constantly check on things such as P.H, Chlorine and turbidity. This is very important to the community that we have clean water to drink every day.
Laboratory ABC uses both glass pipettes (1mL to 5mL) and disposable plastic pipette tips- yellow (20μL), blue (1000μL) and white (5mL). Glass pipettes and white pipette tips are currently washed and reused. Blue and yellow tips are discarded.
Many people often wonder if drinking faucet or even spring water is safe and sanitary for their bodies. Many people feel as if their drinking water becomes contaminated and polluted because the water comes from foreign places. It is imperative people study their drinking water to ensure we are putting fresh water into our bodies. If we put polluted and unsafe water into our bodies, we run the risk of illness and other things we try to avoid. Some topics that will be covered in this research paper will consist of polluted water, our digestive system, faucet water and spring water. These topics are important as background information because these are the main sources for water and ones digestive system can make the determination whether or not the water is polluted.
“Water is life's matter and matrix, mother, and medium. There is no life without water. (Szent-Gyorgyi)” This powerful phrase was coined by Albert Szent-Gyorgyi, a Nobel Prize winning biochemist. Even in the early 1900’s when Albert lived, people were talking about water pollution. Pollution is still even today, a hot topic of politics. According to Merriam-Webster Dictionary, pollution is “the action of polluting, especially by environmental contamination with man-made waste.” Pollutants can be more than synthetic waste. Pollutants can be natural such as soil, volcanic ash, and minerals. Whether the pollution is natural or accidental, humans should always carefully monitor pollution in our waterways. Pollution can affect the life from plants to wildlife, and even humans. Therefore, having regular water testing is important for maintaining and monitoring pollution, animal populations, and overall water quality.
Ground water is present below the surface in porous rocks and is susceptible to contamination by natural and especially human related activities. Large amounts of chemicals like soap and detergents, fertilizers and pesticides, pharmaceutical by-products are discharged in to fresh water aquifers every day. These contaminants leach in to the soil and dissolve in ground water. Different contaminants have different rates of solubility and degradation once they reach the underground water table either by simple flow or by the downward movement of rain water. The ground water may become contaminated with both organic and inorganic substances especially heavy metals like Cadmium, Chromium and Nickel, etc. (Christensen et al, 2001). Pharmaceutical wastes can cause cancer in human cells. (Krifa et al. 2013). Many pharmaceutically active chemicals reach
Now take another glass jar and place a coffee filter. On top of the filter place about one gram of sand. Pour the 250 mL of pond water over the sand.
Waste/Drinking water disinfection serves two main purposes. The primary purpose of disinfection is to kill or inactivate pathogens. The secondary purpose is to provide a disinfectant residual in the finished water and prevent microbial regrowth in water distribution system. Accordingly, in water treatment practice, the term disinfection is used to refer to two activities: (i) primary disinfection for inactivation; and (ii) secondary disinfection for residual maintaining.
We are all are aware that drinking adequate water and maintaining hydration is necessary to support a healthy body, but have you ever considered that this key element to survival may actually be hindering your ability to thrive? The next time you sit down to enjoy a glass of water, consider that there are hundreds of potentially harmful chemicals that may have found their way to your glass! Don’t put it down just yet, first we need to explore several of the chemicals commonly found in our drinking water, and comprehend how they affect our physiology. To do this, we will research how water sources become polluted, the ways in which it is treated, and any chemical regulations in place. Once these topics are understood, we will identify the most effective measures an individual may take to minimize their risk of chemical exposure from contaminated drinking water. The investigation of any possible alternatives or modifications that can be made to the existing system is also crucial, as it could lead to the overall improvement of our country 's drinking water.
This report shows in details different methods that may be conducted in order to test the quality of the water. First of all, the water quality is defined by its characteristics. They may be biological, chemical, and physical. The water quality standards differ due to several environmental impacts.
A few types of water contamination are extremely self-evident: everybody has seen TV news footage of oil spills recorded from helicopters flying overhead. Water contamination is normally more subtle and much harder to recognize than this. However, by what method would we be able to gauge water contamination when we can 't see it? How would we even know it 's there?
Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water), but water purification may also be designed for a variety of other purposes, including meeting the requirements of medical, pharmacological, chemical and industrial applications. In general the methods used include physical processes such as filtration,sedimentation, and distillation, biological processes such as slow sand filters or biologically active carbon, chemical processes such asflocculation and chlorination and the use of electromagnetic radiation such as ultraviolet
The lab report focuses on the experiments showing how contaminated water can be turned into uncontaminated water. The process was interesting to do, as well, watch happen with my own two eyes. The three experiments completed were: 1. Effects of Groundwater Contamination, 2. Water Treatment, and 3. Drinking Water Quality. During the experiment I used the tools provided in the Lab Kit, which included: Glass Beakers, gravel, sand, charcoal, cheesecloth, oil, and detergent, different brands of water, vinegar, alum, and bleach. All of which showed the contamination of the water once I started the
