Water Analysis Lab Report: Mccomas
Water Analysis Lab Report
Purpose:
In this lab we will be testing a number of water samples. These water samples come from various water sources. Each of these water samples will undergo four different tests. The four tests include a pH test, a conductivity test, a total and phenolphthalein and alkalinity test, and a total hardness test. This lab requires comprehension of lab material and techniques learned in prior labs (Kippenhan, 2012).
Procedure:
Each member of the four person group was responsible for collecting a 500 mL sample of water. For this lab, each water sample was taken from a site on the University of Toledo campus. Cody’s sample was taken from a sink in McComas …show more content…
Addison’s sample, which was collected from a water fountain in the student union, had a pH of 5.667, had a TDS conductivity value of 172.5 mg/L or ppm, had a phenolphthalein alkalinity of 4.0 ppm, had a total alkalinity of 15.0 ppm, and had a total hardness value of 63.1 ppm.
Rachel’s sample, which was collected from a water fountain in BO, had a pH of 7.788, had a TDS conductivity value of 151.5 mg/L or ppm, had a phenolphthalein alkalinity of 10.0 ppm, had a total alkalinity of 14.0 ppm, and had a total hardness value of 34.0 ppm.
During this lab we realize a lot of questionable thing about the water we drink every day. Sometimes when we think something will be the same it usually never is, such as the two drinking fountains having different results than expected. Also we realized that the difference between drinking fountain water and sink water are quite similar except for not having the same pH. The tests we preformed are very important in trying to figure out a safe way for water to be
