Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and

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

Analysis of Food Dyes in Beverages Samantha Sequito and Anna Steenland Lab Performed: December 3‚ 2013 Lab Due: December 13‚ 2013 Introduction: Different amounts of FD&C Blue I were diluted with water to make eight differently concentrated 10 mL solutions. Samples were placed in the spectrophotometer to determine the percent transmittance of FD&C Blue 1. All of the data was summarized in graphs to predict the concentration of FD&C Blue I in a sample of Gatorade.

The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4‚ 0.8‚ 1.2‚ 1.6‚ 2.0 mg/ml of bovine serum were used to

Chem 105 Guide to the Formal Laboratory Report The purpose of a formal report is to communicate effectively to another person the goal‚ procedure‚ data analysis method‚ and results of your laboratory work. The report is divided into several well-defined sections. Each section must be present in a complete report. To earn an outcome point for the laboratory report‚ a student must submit a formal lab report that earns a score of at least 90/100. Each error (factual‚ grammatical‚ typographical

Floyd Askew 3/19/13 CHEM 1211L Lab Report Introduction The purpose of this lab is to use volumetric analysis to determine the concentration of unknown substances. A sodium hydroxide solution is standardized to assist in finding the concentration of an acetic acid. An indicator must be used to pin point the equivalence point‚ the point in which 1 mole of a substance is equal to 1 mole of another. When that is found‚ we can determine the concentration.
