Water Filter Experiment

448 Words2 Pages

The last step for our experiment was creating a filter to clean our water. First cut the bottom off of a plastic bottle off and take the lid off. Next put the filter over the lid of the plastic bottle and place the bottle with the filter side in the 100 mL beaker. Once the bottle is in, pour an inch of charcoal, then another inch of sand. Lastly pour an inch of small rocks into the bottle as the top layer and pour in the contaminated water. The procedure for this experiment is to first get your contaminated water in a 100 mL beaker and check the pH with the pH probe (Instructions are in paragraph five).Once the pH is known pour the water in a cuvette and test the contaminated water with the colorimeter for clarity (instructions in paragraph six). After finding the clarity create the filter and pour all the contaminated water through the top so it falls through the filter and into the beaker below. After the water goes through the filter pour the water from the beaker below the filter into a cuvette and test the filtered water for the new clarity and write it down. Next pour the cuvette water back into the beaker and measure the pH with the probe and record the new numbers. …show more content…

The pH in the water is supposed to be at 7 but is at 8.33. That amount and is lowered due to the filter it goes through. The clarity of the water is another variable that is changed and lowered greatly from 71.1% to 44.1% because it went through the

An area was chosen along the stream where the water was moving quickly, and our teachers were careful not to stir up sediment. The bottle was then submerged in water with no way for air to get in, and once filled they used the lid to seal it. The temperature of the water was gained by placing a thermometer in the same area the sample was taken from and was left there for one minute while results were recorded. Water samples can also be used within the hour, or placed in the refrigerator until use. Testing in class was difficult, but with a few attempts we were able to conduct

One test conducted was the measure of nitrate in the water. If there is too much nitrate it grows algae which is then eaten by bacteria, and can cause Eutrophication. Another test was done to determine the amount of BOD, which shows how much dissolved oxygen is needed by Aerobic bacteria in order to break down material. Ph is responsible for how acidic or basic the water is. If a body of water has a high ph it can be unsuitable for aquatic life.

To do the temperature and dissolved oxygen tests, stick the probe in the water, and it will show numbers. One will be the dissolved oxygen in ppm (parts per million) and the other will be the temperature of the water. To do the pH test, stick the pH paper in the water and compare the color it turns to the scale. To test nitrates, put clear water in a container and dirty water in another, and put powder in them. Shake them and then compare the color they turn to the scale.

Our professor gave us the tools needed to carry out this experiment. They consisted of glass beakers, a spray bottle of distilled water, tissue paper, and most importantly the pH meter. The first step was to rinse off the beaker with the distilled water in order to purify it, then we wiped it dry. We put enough liquid of our first sample into the clean beaker, and put the probe of the PH meter, and waited till it stabilizes, then we recorded the PH into the table. Then, we cleaned the meter and beaker and

Before starting the heating process, measure the weight of the crucible with its cover first and then tare the balance, and after that adding about 1 gram of the sample to the crucible with its cover, and then weigh it. Moreover, it is possible liberating harmful gases during the process of heating; therefore, being careful is important. The heating process ends when this sample changes the color to brown because water of hydration is removed to the sample. Additionally, give time to the small cool down and measure its weight. Next, transfer the sample to a 50 mL beaker and mixes with distilled water, which gets by rinsing the crucible with its cover in 8mL, so the solution is generated.

The titrations were all a bit different and that was because they all contained different liquids. The first titration, acid into water, showed a noticeable drop in ph after approximately 5.5 mL of acid was added and was consisted in showing low numbers. This determined that the first hypothesis, stating that the pH would go up when acid was added into water, was false. Dissimilarly to the second titration, base into water, the pH showed a noticeable increase after around 10 mL of base was added and once again, remained consistently high in pH. The third titration, acid into liver homogenate, the pH decreased a bit at 8 mL of acid, but remained fairly consistent at 12 mL. The fourth titration, base into liver homogenate, opposite to the the previous graph, increased in pH slightly at 20 mL, but once again, stayed consistent from then on out.

Discussion: In this lab, we used two techniques to purify a liquid. The two techniques we used were, simple and fractional distillation. Simple distillation separates distillates from less volatile substances. At the start of the lab the apparatus is set up for simple distillation.

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.

There are many unknown ions found in almost every water on earth. Some water sources are more clean, like a freshly shocked pool. Some water sources are not so clean, like a dirty pond. Clean water is more important than dirty water, because if water is dirty there could be the chance of getting disease, or the chance of the animals that are eaten from the water source getting a disease. The sample that will be used for this experiment will be water from a fire pond.

Drinking tap water reduces potential health and environmental risks. To begin with, consuming the tap water rids of the accumulation of plastic bottles that can be harmful to the environment. In addition, the consumption of tap water can emanate from our basic foods to help prevent potential health risks. For example, tap water can be found in solid food, fruit, vegetables, soups, and caffeine products, As demonstrated, there’s various ways to consume tap water through drinking and eating to prevent potential health risks.
