mix it with water to create a solution if the compound is soluble and then to test for the anion with the specific anion tests and lastly, use the ammonium test or the cation flame test. There are many tests for anions like the test for chloride, iodide, sulfate, nitrate, acetate and other anions. The cation tests are the test for ammonium and the flame test where a person burns the compound and the color of the flame determines what the cation is. Quantitative proof can be found by determining how
I: Purpose In this lab, our purpose was to observe the colors that were released by various metal ions. We wanted to be able to tell which element was which based off of the color of their flame. We also wanted to look at flame testing as a method of detection of metals. II: Procedure Acquire small samples of salts in marked test tubes. For each sample, add an amount of salt the fills the very tip of a scoopula. Pour roughly 15 mL of 6M HCI into a 50-mL beaker. Clean the wire loop by dipping
Lauren Calso September 29, 2014 BIOL 240 Lab Report Gram Stain Introduction Various methods are used to identify unknown bacteria. A popular method to determine unknown bacteria is called a Gram Stain. A stain is coloring a specimen with dye. A Danish physician named Hans Christian Gram developed the Gram stain method in 1844. He studied at the University of Copenhagen and became a professor of Medicine. When differentiating between two types of pneumonia, he found that most bacteria are either
Forensic scientists often spend long days in the crime lab testing samples they can also frequently encounter unpleasant working conditions and face misconceptions from both the public and law enforcement professionals regarding the nature of their work. Most forensic scientists work a traditional 40-hour week
person has died; it happens when their body has an amount of potassium still left in their muscles that caused them to twitch or move (page 61, paragraph 2). Later on, when Roach is telling how medical examiners use color codes when looking at many reports at one time, her book mentions extremities and a transection of the body (page 117, paragraph 1). In anatomy, when you are talking about extremities you are referring to arms and legs; in the book they use this to explain if a passenger has lost an
