The Unknown

Introduction This accuracy lab of titration report experiment will discuss how to find the unknown substance molarity. By using some of the lab equipment to help guide and identify the molarity of the unknown substance. I believe that it will take around three hundred drops of sodium hydroxide (NaOH) for it to be able to reach to its endpoint of the unknown substance. My reason behind my hypothesis is… Methods In this lab experiment we use a buret to…

Unknown #11: Introduction: My patient’s name is Cara, she is currently a freshman living in a dormitory with three friends. Just two weeks in, she catches the flu. Her roommates made her soup for the next couple of days from their shared pantry of foods. Cara however progressively becomes worse and now exhibits severe symptoms of nausea and diarrhea. This study was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of…

Determining Percent Composition of Unknown Copper Ore Sample Iodine-thiosulfate Method: An Analytical Method The objective of this experiment is to eliminate all interfering species from a sample of unknown copper ore in order to later determine pure copper content. Copper ore can be found in a mineral that contains pure copper and other species that is mined and can later have copper extracted from them (Taher, 1999). To eliminate all interfering species, such as Iron, Arsenic, and…

wreath at the Tomb of the Unknown Soldier is a tradition that has performed by countless students over the past decade at Woolwich Central School. However, out of all of the applicants who have tried to or participated in this once in a lifetime opportunity, they may have missed the true meaning of it. Although I believe I have not, most kids try for the experience only, or to honor our school or family, but what this ritual is truly about is remembering and honoring the Unknown Soldiers.…

The unknown base concentration of a sodium hydroxide solution can be determined by titration potassium hydrogen phthalate (KHP) with an unknown concentration of sodium hydroxide NaOH. The average molarity of NaOH determine by the moles and volume of the KHP and NaOH. (Eq 1). KHC8H4O4(aq) + NaOH(aq) = H2O(l) + NaKC8H4O4(aq) (Eq 1) The unknown concentration of white vinegar can be determined by the white vinegar with the known concentration of…

morphological unknown lab we used 2-3 lab periods for. Before going into lab, I started to create my own dichotomous key for all the microbial species we’ve been working on, assuming we’d have a species we previously worked on. My dichotomous key went from from gram stain to respiratory use and to fermentation results. I quickly realized that I shouldn’t have been working on this as my first go to. I mentioned in a past reflection that I was unconfident in myself to identify my unknown for this…

Van Tran Microbiology Tuesday 5:00 May 5, 2015 Unknown Sample # 7 1. Introduction: Using biochemical tests are a good way to identify unknown bacteria from a sample. It is basically a similar to a trial and error method, but rather than using trial and error a person would be using positive and negative results. Using biochemical tests will help a person identify certain characteristics of the unknown bacteria through a series of chemical tests. Of course more than one biochemical tests…

General Unknowns Bacterium Vitality en Vida Bacteria play a vital role in our daily lives. It is therefore our right to know the importance of being able to distinguish certain strains of bacteria. With the right knowledge we would be able to come up with a cure for a disease. An identity gives way to knowledge, to better understanding and access to information on how an organism works and how we can prevent its worsening effects or isolate its benefits. Scientists have been trying to…

Thu Phan Khanh Nguyen Dr. Jennifer Bess MCB - 2000L - 87248 11 April 2024 Unknown Lab Report: Unknown #20 Unknown Number: #20 Bacteria identified as Enterococcus casseliflavus. Introduction: Many bacteria have existed for hundreds of millions of years that we have not yet discovered. Those bacteria can survive under the thawing layers of ice, so when it melts, they are awakened and become strongly active. These bacteria are consumed by plants and animals, whom we also consume as our daily…

The focus of this lab was to identify an unknown organism based on its characteristics and the results from each of the tests. There will be various of test to choose from in order to identify the unknown organism, which will eliminate numerous possibilities and narrow it down to one. All the fundamental skills that we have learned and practiced in the lab will be used to perform on our unknown such as aseptic technique, microscopic examination, the use of differential media, and determining if…
