Specific Objective: Carry out test for reducing sugar‚ non reducing sugar‚ starch ‚ protein and lipid. BIOCHEMICAL TESTS Reducing and non-Reducing Sugars Sugars can be classified as either reducing or non-reducing based on their ability to reduce copper(II) ions to copper (I) ions during the Benedict’s Test. Reducing sugar have contain free aldehyde or ketone group and have the ability to reduce copper(II) ions to copper (I) ions during the Benedict’s Test. All monosaccharides are reducing

The psychometric assessment test I evaluated for this project is the Wonderlic Cognitive Ability Test. This test is a popular intelligence test used to assess the aptitude of prospective employees for learning and problem solving in a range of occupations. A man named Eldon F. Wonderlic originally created the test in 1936 and throughout the years alterations and new versions of the test have been created. The test is actually quite simple; the participant is required to answer 50 multiple-choice

Proteins Purpose: To test for the presence of starches and protein macromolecules‚ to introduce the concept of variations in chemical compounds. Hypothesis: If biuret is blue after a test for protein‚ then it is a negative result because biuret reagent is blue to begin with. If a solution is pinkish purple‚ or purple‚ then the test for protein is positive. The test solution for starches is yellowish brown. If any substance that is yellowish brown when mixed with iodine‚ then the test for starches is

The T-TEST 1.0 INTRODUCTION The t-test was developed by W. S. Gossett‚ a statistician employed at the Guinness brewery. However‚ because the brewery did not allow employees to publish their research‚ Gossett’s work on the t-test appears under the name "Student". The t-test is sometimes referred to as "Student’s t-test." Gossett was a chemist and was responsible for developing procedures for ensuring the similarity of batches of Guinness. The t-test was developed as a way of measuring how closely

cation and anion analysis is that in anion analysis‚ a series of separations of the ions from one another is usually not the most efficient way to determine their presence. Instead‚ only some separations will be made‚ and the initial test solution will be used to test many of the ions. Refer to the flow chart at the end of the experimental directions as you proceed. First you will prepare and analyze a “known” solution which contains all six of the anions. Then you will analyze an “unknown” solution
