Potentiometric Titration of Sodium Carbonate Otieno O. Victor University of Detroit Mercy Quantitative Analysis Lab CHM 3880 Fall 2011 Partner: Edwin Gay Abstract The PH at each point during the titration of sodium carbonate unknown sample was determined. An Unknown sample of Na2CO3 was titrated with a standard HCL solution. In addition to titration‚ the pH at each point of titration was measured using PH meter. The % of the unknown Na2CO3 was 25.83% Introduction1 The purpose of this experiment

Laboratory Report The Plasma Membrane I. Introduction The Plasma membrane is the edge of life‚ the boundary that separates the cell from its surroundings. It controls the traffic of materials in and out of the cell. (Reece‚ 2011). It is incredibly thin that is very vital in maintaining the integrity of the cell. Not only does the plasma membrane bind the other organelles‚ it also forms a dynamic structure which gives them their remarkable activity and selectivity. (Hickman‚ 2008). Diffusion

Although many people go through extreme hardship during war‚ they can find things to love that gives them the endurance to pull through. The novel Salt to the Sea by Ruta Sepetys‚ details the story of a group of refugees that are desperately trying to escape the encroaching Russian army who are brutally pillaging‚ raping‚ and massacring everything in their path‚ by getting to the ship the Wilhelm Gustloff. The Wilhelm Gustloff is attacked by a Russian submarine and sinks and only four out of the

time it takes (if at all) for the iodine to remain its orange-yellow color.2 Hypothesis Enzymes must be kept at certain conditions to function at its optimum level. Indeed‚ factors that may cause the enzyme to denature are: pH‚ temperature‚ and salt concentrations. When an enzyme is denatured‚ it can no longer bind to the active site‚ and therefore cannot carry out its functions. Therefore‚ adding pH buffer to amylase will affect the enzyme’s function upon its addition to starch‚ which can be

Lab Report Janice Chisholm SCI207: Dependence of Man on the Environment Instructor: Lee Ott April 28‚ 2013 1. What patterns do you observe on the information table 4? While observing the information in table 4‚ it appears that the number of fish changes from time to time and the oxygen increases and / or decreases when this occurs. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water?

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

INTRODUCTION There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease to knowing the correct microorganism in order to make antibiotics. This study was done by applying the following methods; OF Glucose‚ Indole Production‚ and Malonate Utilization test for the identification of an unknown bacterium. The methods will assist in determining the unknown bacterium found in a 55 year old male that was passing blood and mucous
