Lab‚ Week ASEPTIC TECHNIQUE AND BACTERIAL ANATOMY AND MORPHOLOGY Introduction Part I: Aseptic Technique The purpose of this experiment is to become familiar with the specific microbiological technique known as the aseptic technique‚ which is used to avoid contaminating cultures. In this case a pure culture of an unknown organism was introduced to a sterile medium of Phenol Red Glucose Broth Durham. The culture was obtained from a 52-year old male truck driver who is complaining

Determining the Properties of Different Acids and Bases Yamin Liu November 16th‚ 2017 Chemistry 1021 Section: 427 Benton Smith Discussion of Results The goals of this experiment were to find the identities of four unknown compounds and to first determine the pH. We then were required to run a series of anion and cation tests to determine the composition of the unknown solutions. To get more knowledge about these solutions we ran a series of dilutions to see if

test-tube and the temperature of the water was measured. The test-tube was placed on a stand and the first food sample was lit on with a glowing stick that had been lit by a match. The food sample was kept under the test-tube until the flame burned out. Once the flame burned out‚ the temperature of the water was taken and written down. This procedure was repeated three time with all three Brazil nuts individually. Cheerios (Sample B): 3 Cheerios were taken and each weighed individually. Their weights

observe chemical reactions to determine the presence of specific anions and cations. Compare your observations with the reactions of the known solutions and the unknown solution to determine the ions present in the unknown solution. You will use a flame test for the cations‚ Na+‚ K+‚ and Ca+2 Perform qualitative tests for Ca+2‚ NH4+‚ Fe+3. Qualitative tests will be used to identify anions‚ Cl-‚ SO42-‚ PO43-‚ and CO32-. Expected results of the qualitative test and the reactions are included in your

Introduction: To do the lab exercises for this lesson‚ you need to know a little bit about light. White light consists of all the colors of the rainbow mixed together. Diffraction refers to various phenomena which occur when a wave encounters an obstacle. In classical physics‚ the diffraction phenomenon is described as the apparent bending of waves around small obstacles and the spreading out of waves past small openings. Isaac Newton thought that light must be a particle because particles of light
