OBJECTIVE The main objective of this experiment is to carry out qualitative analysis to identify metal cations in unknown solution 1. INTRODUCTION An unknown material can be determined by using simple chemical tests and separations which is called as inorganic qualitative analysis. The separation of cations depends on the difference in their propensity to form precipitates. Separation scheme is used to classify cation into five groups on the basis of their physical and chemical behavior opposed

Phelps‚ Biology 205 MW 2:10pm. Unknown Organism Paper The unknown organism tested in the Mesa lab was collected from in between the toes of my puppy‚ Riley. The original culture grown consisted of dozens of visibly different organisms of varying colony colors and growth patterns. I chose to test a smaller‚ red colony for my experiments. Based on its gram reaction and oxygen requirements‚ the following tests were performed to reach my presumptive ID: Test Performed Result Gram Stain +

Good evening Dr. Behizadeh‚ I hope this email finds you well. I first would like to start out by saying that it was a privilege to be in your class last semester and I really learned a lot. I am writing you this email today because I have an escalating dilemma that I need some resources on. I recently received a job opportunity from a private school that I am currently working at‚ and things seemed to be going well. At the beginning of the school year I was receiving complaints about

As an eight-year-old pipsqueak who was regularly pitted against the twelve-year-old Goliaths of Albuquerque’s 12U tennis division‚ losing 0-6‚ 0-6 became a natural part of life‚ and I hated it. In fact‚ my tournament to-do list consisted of a dreadfully long car trip‚ suffering defeat upon defeat to another unnamed middle-school giant‚ and then drowning myself in a sea of tears while my dad lectured me about "unforced errors" on the trip home. As a result‚ I started to run away from tennis. I performed

I’m not as glamorous as I might seem. I’m just an ordinary student in 10th grade‚ who likes to learn things. Others may be more charismatic or handsome‚ but I have something that they do not. I posses an essential life skill; initiative. You (as the readers from the National Honors Society) may think that what I am saying is absurd‚ but I am here to prove my worth one paragraph at a time. I am a well educated individual who has repeatedly demonstrated initiative and high standards of reliability

Introduction: During this unknown lab report various test were performed to differentiate microbes from each other and to compare metabolic and biochemical process. The gram stain distinguishes between Gram positive and Gram negative bacteria based on the composition of the cell wall. The Gram stain procedure distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet. Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan

BSE-Biological Sciences III-3 Microbiology (Lecture) Microbiology Written Report REPORT NO. 1 Prokaryotes: Bacteria Most of us have been conditioned to think of bacteria as invisible‚ potentially harmful little creatures. Actually‚ relatively few species of bacteria cause disease in humans‚ animals‚ plants‚ or any other organisms. In fact‚ all organisms made up of eukaryotic cells probably evolved from bacteria-like organisms‚ which were some of the earliest forms of life. In this chapter

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 in his stool. The patient had no pain but mild discomfort during bowel movements. The doctor noted inflammation of the lining of the
