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

Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements (halogens) and their compounds. More specifically‚ the solubility properties of these halogens will be used to predict their reactions. The relative electronegativities of the halogens will be determined. Halides‚such as Cl-‚ Br-‚ and I- will be used to make these determinations. Because this lab is qualitative rather than quantitative‚ there are no calculation

2013 Pink and Bubbly Research: Phenolphthalein is an acid/base indicator which expresses the properties of an element. It is colorless when it is an acid and pink when it is a base. Ammonium is familiar base‚ used for cleaning oils and grease from any types of surfaces. Ammonium is a fairly strong base with a pH of 11 and will dissociate completely into an aqueous solution (water). Water is universal and has a neutral base with a pH of 7. A Danish chemist named Johannes Bronsted and an English

Lab Report: Toothpickase and Enzymes September 19‚ 2012 Olivia DePhillips Lab Partner: Joy Morgan Meyers Signature: Introduction Enzymes are biological molecules that catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process‚ called substrates‚ are converted into different molecules‚ called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Like all catalysts‚ enzymes work

sometimes contain iodate ions; therefore‚ this part was performed to detect any iodate ions. In the blank determination experiment‚ exactly 2.00 grams of KI was dissolved in 50 mL of distilled water and then acidify with 5 mL of 3M sulfuric acid. After the acid‚ 5 mL of starch was immediately added into the solution. The solution didn’t turn into a blue color‚ so a blank correction was not needed for the standardization and analyzes volumes. After determining that a black correction is not needed
