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

The reason for three tests for each acid is to get the most accurate amount of base‚ to neutralise the acid. 1.2 Aim To determine the concentration of acetic acid in some commercial

Tim Readmond AP Biology Lab Report I. Title a. Modeling Diffusion and Osmosis II. Introduction a. If one places a 1.0 M solution of glucose inside a bag and then places that bag into a beaker containing a 1.0 M solution of sucrose‚ the percent of mass lost in the bag is 10.5%. The solution in the bag is hypertonic while the solution in the beaker is hypertonic‚ which is why water moves from the bag to the beaker and the bag loses mass. b. The purpose of this experiment is to see whether

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

1 Measuring and calculating equilibrium constants Clearly‚ if the concentrations or pressures of all the components of a reaction are known‚ then the value of K can be found by simple substitution. Observing individual concentrations or partial pressures directly may be not always be practical‚ however. If one of the components is colored‚ the extent to which it absorbs light of an appropriate wavelength may serve as an index of its concentration. Pressure measurements are ordinarily able to measure

to analyze the solution of Ba(OH)2 of an unknown concentration. In order to obtain the quantitative analysis‚ the exact amount of a particular compound or element present in sample‚ two procedures were performed. The first procedure was by conductimetric titration and by gravimetric determination. The conductivity was analyzed during the reaction between the sulfuric acid (H2SO4) and barium hydroxide (Ba(OH)2). Through the conductivity‚ the equivalence point can be determined; from there‚ the concentration
