The Chemistry Of Natural Waters Lab Report
Olivia Lapchak Chemistry 113-004 23 February 2023 The Chemistry of Natural Waters Introduction When considering the amount of bottled water that is consumed every day, very little is contemplated when choosing what brand to buy. The contents in each of the water brands is vital information one should know before purchasing because it informs the consumer about many measurements including Calcium and Magnesium concentration, total dissolved solids, total hardness, and the water source for each brand. Each of these factors play a role in deciding whether a brand is healthy for the body, or not quite ideal. Knowing what each of these measurements suggests and how they work together is the first step to understanding water content and how greatly …show more content…
It will ultimately measure the absorption of calcium and magnesium for the sample. Next is the usage of the conductivity meter; after filling a well with the sample, place the probe into the well. This will read a total dissolved solid value for the …show more content…
Each sample had quite a different value for hardness, causing a high standard deviation and more spread-out results. Because of this, the other factors were relied on heavily to distinguish between the different waters because of the lack of similarity. Although B1 and C1 can be definitively identified, A1 could also be predicted using the components within the
Salt Creek And Barker Lake Lab Report
566 Words | 3 PagesThese water samples were all taken from the shores of Barker Lake, meaning that they should be similar and they were. Our class data did not seem to be very precise. This is shown in the data in sites 1 and 2 when one group had 9 ppm and another group had 20 ppm. These samples both came from Salt Creek and should have been similar but were not. Another example of class data being inconsistent or imprecise was on site 4 when one group’s results showed 3 ppm and another group’s showing 6.
Unknown Compound
1270 Words | 6 PagesGoals The primary goal of this experiment was to identify an unknown compound by running various tests to determine the qualitative solubility, conductivity, and pH value of the compound. Tests were also performed for the presence of specific cations and anions in the compound. The second goal was to discover the reactivity of the unknown compound by reacting it with different types of substances. The third goal of this project was to calculate the quantitative solubility of the unknown compound in water.
What Is The Chemistry Of Natural Waters Lab Report
528 Words | 3 PagesThe procedure for this experiment is found in Stephen Thompson’s PSU Chemtrek on p. 10-15 through 10-22 under the “Chemistry of Natural Waters” lab. For the testing, four tap water samples were obtained from Virginia and State College, Pennsylvania—McDonald’s, the Atherton Hotel, and McKee Hall. Each member of the group proceeded through the testing methods in order to determine the hardness for a particular water sample. In accordance with the procedure, the AA technique was used first. Because the water sample from McKee Hall had no suspended particles, no filtration was required prior to testing; however, the sample was diluted with a 1:1 ratio.
Susquehanna River Lab
627 Words | 3 PagesTo 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.

Annie Leonard's The Story Of Bottled Water
154 Words | 1 PagesWould you rather drink water package in a bottle or water that can be found in a drinking fountain? One of the problems with water is that people try to choose which one they would think is the most safe, but sometimes people have the wrong perspective on which water is more healthier. On one side of water, bottled water, it is used commonly throughout the world, being the second most popular commercial beverage in the United States. On the other hand, tap water is found locally in drinking fountains, but is the least favored among the people of the world. Annie Leonard’s position on bottled water through her videos and her script, “The Story of Bottled Water,” clearly demonstrate how tap water is a more viable source than bottled water.
The Color Of Water Analysis

The Chemistry Of Natural Waters Lab Report
2992 Words | 12 PagesAccording to the experimental results, the unknown water sample D4 had a calcium concentration of 34.9 ppm, a magnesium concentration of 40.3 ppm, a total hardness value from AA of 236, an average total dissolved solids value of 225, and an average hardness from EDTA value of 489 (see table 3). While the other two samples had low hardness values, this one has a large value, meaning it came from a European-sourced company. This hardness is very high compared to the water quality report values for any of the European values, however the experimental range is 283-695 when including standard deviation. The high standard deviation comes from the fact that a single-well EDTA titration was necessary to determine the hardness, and a single-well is less accurate than a serial because you cannot see each step next to one another, so it might be harder to notice when the endpoint is reached. According to their water quality reports, Evian has a hardness of 310 ppm⁹, and Perrier has a hardness of 390 ppm¹⁰.
The Color Of Water Analysis
144 Words | 1 PagesThe Color of Water explores life in two very different perspectives, each with their own purpose and meaning of living. However, despite their vast differences, they are harmonious in a sense that these two distinct characters, James McBride and Rachel Shilsky, seeks for an identity that would ultimately satisfy their means for individuality and the awareness of their connection to the universe. For instance, James questions his true relation towards his so-called mother, as race sets them apart, and Rachel, though she omits to reveal her mysterious past, has found her value in society by her strong-will and sheer acceptance - embracing a culture that could cause personal harm to her life, yet unfazed at that. Having learned about the conflicts
Water Hydration Lab Report
603 Words | 3 PagesIntroduction: In this lab, of water in a hydrate, or a substance whose crystalline structure is bound to water molecules by weak bonds, is determined by heating up a small sample of it. By heating, the water of hydration, or bound water, is removed, leaving only what is called an anhydrous compound. Based on the percent water in the hydrate, it can be classified as one of three types: BaCl2O ⋅ 2H20, with a percent water of about 14.57%, CuSO4

Chemical Weathering Lab Report
524 Words | 3 PagesIt was suspected that the more acidic the solution, the more chemical weathering would occur. Because the 50% vinegar had a pH of 2, it was the most acidic and the distilled water had a pH level of 6, making it the least acidic of the four solutions. The 10% vinegar had a pH level of 4 and the soda water had a pH level of 5.
In Red And Brown Water Analysis
672 Words | 3 PagesWhile watching the play In Red and Brown Water I felt like I had traveled to another world in Lil Elegbas dream. The dream I witnessed is about Oya passing on to afterlife. Oya is floating in the water, which is filled with blood from her ear. At this point in the play we do not know that the blood is originating from her ear that was sliced off to give to Shango. The dream scene was way more vivid in person then when I read it.
Grey Water Shampoo-Chemical Characteristics
829 Words | 4 Pages3.1. PHYSIO-CHEMICAL CHARACTERISTICS The characteristics vary from the source as well i.e. kitchen wastewater is considered to contain higher amount of organics and physical pollutants as compared to that of laundry or bathroom wastewater (Eriksson et al., 2002). Surendran and A. D. Wheatly (1998) have found that the characteristics of grey water were found to be similar to that of domestic sewage except in terms of the ammonia and bacterial content The physical characteristics of waste water considered are the temperature, colour, turbidity and total suspended solids. The temperature of grey water is slightly high (usually lies between 18-38 degree Celsius) due to use of warm water for bathing (Eriksson et al., 2002). Turbidity of grey water may vary from 5.6 NTU -33.6 NTU for low strength and can be about 67.4 NTU for high strength waste water.
