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
At the first station I was at, we were looking for macroinvertebrates and crustaceans. When we found one of the insects we had to determine which group they belonged in. One way to determine if the water is polluted is to look at which group the critters are mostly from. My group and I tested this by taking turns going into the creek and finding a rock to bring out. When we brought the rock out of the water and back to our group we had to make sure to turn the rock over because the critters normally live on the bottoms of the rocks and most likely would fall off if you didn’t turn it over. After we all took turns a couple of times
Several species and organisms rely on water to survive. Some organisms use it as a source to drink and others uses water as their living environment. This experiment is to calculate many aspects of the water that surrounds Corpus Christi. Water is the key to life on Earth and thus why water is so important. According to the Lab Report water quality is the quality of water and if it is considered acceptable drinking water. Water quality consist of its chemical, physical and biological characteristics. These properties can be studied through pH testing, nitrogen testing, Phosphorous testing and many other useful ways. Water quality is important because it allows scientist to identify if the water is in a good condition to drink or sustain life overall and it dramatically effects how healthy it is. The objective of this lab was to experiment if the water quality around the Corpus Christi is a reliable source of water for organisms and to reach an understanding of the water quality of the water surrounding Corpus Christi.
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.
One sure way of knowing that the water we drink is clean is by using water dispensers. These dispensers provide clean and clear drinking water, hot or cold. We see a lot of these in offices and schools for people to enjoy. Using water purifiers

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.
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.
Five disinfection agents are available in drinking water treatment today (i) free chlorine, (ii) combined chlorine (chloramine), (iii) ozone, (iv) chlorine dioxide, and (v) UV light. The first four disinfectants are chemical oxidants whereas UV light involves the use of electromagnetic radiation. Of the five, by far the most commonly used disinfectants, in both plants and distribution systems, are chlorine and chloramines. Chlorine dioxide, ozone and UV are also used on a limited basis to meet disinfection goals. Chlorine or chloramines are the most common disinfectants used to achieve secondary disinfection.
Widely varied techniques are available to remove the fine solids, micro-organisms and some dissolved inorganic and organic materials. The choice of method will depend on the quality of the water being treated, the cost of the treatment process and the quality standards expected of the processed water.
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
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?
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
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.
I did some research and found out that there are several substances used to filter water (Gravel and Sand). I decided to make an experiment to find out which substance would best filter the
“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.
