The experiments conducted for this lab report focused on water contamination and filtration. Experiment 1 was effects of groundwater contamination. Oil, vinegar, and laundry detergent were added to clean water with no means of filtration. The clean water was found to be contaminated. A filtration system consisting of cheesecloth and 60 ml of soil was created and the contaminated samples were filtered through it. The soil and cheese cloth did not affectively filter the contaminants. Experiment 2 focused on
The basis of this experiment was to test how different contaminates effect ground water when absorbed. The results were surprising as that I felt any additives would immediately change the entire break up and color of the water. What was most surprising to me was that filtering vinegar through ground water it came out relatively clean. I also believed that when filtered all of the water would have large traces of dirt, but that was not the case with the vinegar. This means that there are still viable ways to filter and purify water.
I was fascinated by this experiment that we recently did on water contamination, tap water versus expensive bottled water. Our water is tap well water. While exploring the topic futher, our research area took place on our kitchen counter where we observed how the test chemicals reacted with the tap water versus the bottled waters. We needed to follow the directions thoroughly, so we got accurate results. We started with test strips of ammonia: all three glasses of water contained: 0 mg/L of ammonia, 0 mg/L of chloride. The 4 in 1 showed: Tap water; 0 mg/L, total alkalinity; 10.0 of total chlorine, 120 mg/L of total hardness. The Dasani revealed 40 mg/L of total alkalinity, 0 mg/L of total chlorine, 0 mg/L of total hardness. The Fiji
Water contamination using the filtration process was observed on a smaller scale using liquid laundry detergent, vegetable oil, and vinegar. These products were tested and observed for differences in color, smell, and consistency. Three different kinds of water products from; tap water, Dasani water, to Fiji bottled water were tested and observed using chemical test strips. This was to understand that bottled water did not have a difference from regular tap water. When contaminates are introduced to the elements and effect the water supply they can have an adverse effect on the human health system. The water that we drink and use in our day-to-day lives is vital and understanding how to keep it clean is the responsibility of all.
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
In this lab students tested the given contaminated (hard water) for the ions present in the water prior to the distillation, and then after the distillate (pure water) was collected, the same procedures were followed to prove the absence of the hard water contaminates. SPAN Chemistry is so called because this dual-credit class spans the gap between high school and the extremely rigorous college chemistry expectations.
Once the water is extracted from the source, it goes through a sedimentation process in order to allow the matter in the water such as silt, sand, clay, and other solutes to settle to the bottom. The water moves slowly allowing the particles to settle to the bottom where a hopper with large scrapers is waiting to gather the particles to keep them out of the moving water which then moves through the filters (“How is water treated?”). The sedimentation part of purification is important because it improves the quality of the work of the filters allowing more particles to be taken from the water. The water filters through sand and gravel therefore causing the leftover particles to get caught in the sand. The water then continues through the sand and into a basin catching the new clean water. Chemicals are added during these processes as well to make sure all harmful bacteria is out of the water. Other nutrients can be added to the water to make it more beneficial to the human body (“How is water treated?”). This method of water purification can be expensive because of all the equipment needed and pipes needed to get the water from the source to the purification
Laundry detergent hypothesis = the water will change in consistency and would probably have suds/bubbles, smell and color (if detergent is colored) would also be altered.
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
Higher amounts of alkalinity help to stabilize the pH (Waterfilters.net 2017). Only one of our samples had any carbonate alkalinity, and that was Sample 4 with 10 ppm. The other three samples had no carbonate. Sample 1 had the highest amount of bicarbonate with 62.2 ppm. Sample 2 had 23.6 ppm and Sample 3 had 38.0 ppm of bicarbonate. Sample 4 had the lowest amount of bicarbonate with 30.0 ppm. None of the samples had any hydroxide alkalinity. The sample with the highest total alkalinity was Sample 1 and Sample 2 had the lowest total
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.
In conclusion, the water is not that polluted, according to the test results. Mostly all of the results were excellent, but only 2 of the results were fair, which is in between poor and excellent. Therefore, the water is not
To calculate the expected number of pipette tips needed per month take the number of pipette tip per sample to multiply it with the average sample analysed per month, 5 x 100 = 500.
