WATER QUALITY 1 Water Quality and Contamination SCI207: Dependence of Man on the Environment Water Quality and Contamination Abstract In this experiment water quality and contamination of groundwater were investigated. First‚ I will observe the effects that many pollutants have on groundwater. I predict that in this experiment the oil and vinegar will create the largest quality of contamination to the water‚ while the laundry detergent will just create a bad smell to it. Considering

LAB Report #3 Introduction: In this lab we have focus on Isolation of bacteria from environment. Microorganisms are found throughout the environment: in the air and water; on the surface of any object such as clothes‚ walls‚ furniture; in soil and dust; and on and in our own bodies (skin and mucous membranes). In order to demonstrate the ubiquity and diversity of microbes in the environment‚ samples from immediate areas of the environment and/or from your body will be obtained and cultured

Solvent/Water Trap Diagram Rodney Atwaters Halle Bair May 28‚ 2013 Chemistry 36100 Introduction The purpose of this lab was to produce benzoic acid by mixing sodium benzoate with hydrochloric acid. The Hydrochloric acid used in the experiment was a stock solution made by mixing HCl Acid and deionized water. HCl acid‚ historically called‚ muriatic acid or spirits of salt‚ hydrochloric acid is produced from sulfuric acid and common salt‚ NaCl (Princeton.edu). Since the early 1900 ’s‚ sodium

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

Bio Lab Report Title: Gram-Negative and Gram-Positive contamination in yogurt. Introduction: There is bacteria that is beneficial and harmful in the human. Yogurt was choosed to be the best example that contains this bacteria. What happens to be the difference between these two types of bacteria‚ and how are they harmful? The bacteria is considered “Gram-Negative‚” and the substance is considered contaminated when there is more negative bacteria than positive bacteria. This will prove or disapprove

Lab Report 7: Analysis of Cereal Introduction: The objective of this lab was to consult for the FDA regarding a recently surfaced scandal involving false reporting of iron content in cereal as well as iron tablets. The makers of the cereal and the iron tablets‚ respectively‚ were allegedly reporting higher amounts of iron in their products than actually existed‚ as a way to save money but continue to provide products with “adequate” amounts of iron. The FDA needed consulting in order to analyze
