Identification of Unknown Carbohydrates using various biochemical tests Date of experiment: 11/10/2012 Name of Student: Vicki Marshall Introduction A series of biochemical tests was carried out to identify unknown carbohydrates. There were six carbohydrates that needed to be identified; they have been randomly labelled A-F. The carbohydrates are glucose‚ fructose‚ maltose‚ lactose‚ sucrose and starch. There was six tests that were carried out to help identify them‚ these were: Iodine Test

Experiment 5- Standardization of NaOH and determination of Molarity of an unknown Acid Objectives 1. Preparation and standardization of a 0.1M NaOH solution 2. To learn the technique of titration 3. Determination of the concentration of an unknown diprotic acid. Introduction Titration can be traced to the origins of volumetric analysis‚ which began in the late eighteenth century. Study of analytical chemistry began in France and the first burette was made by Francois Antoine Henri

Conclusion: (Identity‚ % error‚ other evidence‚ how to improve) The identity of Unknown A is the compound cobalt(II) chloride hexahydrate (CoCl₂•6H₂O).This is justified by the similarities in color of red-purple crystal like grains‚ which is significant in identifying the product out of the eight suggested identities. Only two had similar characteristics which were CoCl₂•6H₂O and CoSO₄•6H₂O. Before unknown A was heated‚ there was a notable common physical property of the substance being red crystal

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 +

Titration Competition” – Lab #8 1. Since all solutions and aqueous solutions have their own pH‚ it is important for all glassware to be clean and dry before performing a titration. Even a slight trace of a different solution could alter the pH and give an inaccurate titration reading. If the glassware is not completely dry after rinsing‚ the small traces of water could make the solution more dilute than it should be thus changing its concentration. 2. Air bubbles in the burette tip is a possible

explore the properties of an unknown compound. An unknown was given and a cation flame test and anion test was performed to determine the identity of the compound. Once the identity was determined‚ the properties were explored. Experimental To determine the cation of the compound‚ a cation flame test was performed. A bunsen burner was lit until a medium blue flame was burning. The given unknown was scooped onto a nichrome wire loop. The wire was held in the flame to determine the cation. To compare the

Experiment H: Identification of an Unknown Organic Compound The objective of this lab was straightforward. We were given an unknown compound and we were to perform an IR spectroscopy and as well as NMR spectroscopy. With the IR spectroscopy‚ I was able to name the functional groups I have on my compound and further confirmed my assumptions by looking at the NMR spectroscopy after. The unknown number I was given was number 203. The molecular weight of the compound was 121. From the molecular weight
