D_____ J_____ CARBOHYDRATES LAB May 22‚ 2013 Pre-lab Questions 1. The water in test tube No. 1 is a negative control. No reaction is expected to occur because water is not a carbohydrate. Reaction by a negative control is evidence of contamination. 2. The color changes expected for positive test results are Benedict’s test: orange to brick red Tollen’s test: metallic silver Starch iodine test: blue-black 3. Identify each of the samples in Part 1 as monosaccharide

Epoxidation Reactions Lab Report 2 Abstract An oxygen atom is transferred from a peroxy acid to the carbon=carbon double bond thus forming an epoxide. Scheme 1. Oxone Epoxidation. Scheme 2. mCPBA Epoxidation. The percent yield for the Oxone epoxidation reaction was 65% yield and the mCPBA epoxidation reaction was 70% yield. Oxone is the greener alternative because using mCPBA is twice as expensive as Oxone and leaves behind the epoxide plus m-chlorobenzoic acid while Oxone creates non-toxic

Majed Al Dhwaihi Chem 151 Lab Prelab Assignment for week 3 Chemical Separation Procedure: Separating the sample: First place a small amount of the spinach provided in the mortar‚ just enough to cover its bottom; combined with the sand provided to break down the call walls. A 1:1 mixture of hexane and acetone was determined to best solvent for this extraction. Knowing this add one mL of the pure hexane and one mL of the pure acetone to the mortar. Grind the contents until the cell walls

AP Chemistry Chapter 17 Additional Aspects of Aqueous Equilibria Chapter 17. Additional Aspects of Equilibrium Common Student Misconceptions • • • • • Students often believe that the pH at the equivalence point for any titration is 7.00. In terms of problem-solving skills‚ this is probably the most difficult chapter for most students. Students tend to find buffers particularly difficult to understand. Students often forget to consider volume changes that occur when two solutions

Lab 19A Answers: 1) If we increase the molarity of NaOH from 0.1M to 0.2M‚ it will actually take less number of drops in order to change the color of the solution. This is because the more concentrated a substance is‚ less of the substance is needed to cause an equilibrium shift. 2) When you add 6.0M NaOH into the iron (III) thiocyanate ion equilibrium system‚ the concentration of Fe3+ ion decreases. This causes the equilibrium system to shift to the left (reactant) side. This is why the solution

Lab 1 Diffusion‚ Osmosis‚ and Water Potential of Glucose Problem: What effects will glucose have on diffusion‚ osmosis‚ and water potential? Background: All living things have certain requirements they must satisfy in order to remain alive. These include exchanging gases (usually CO2 and O2)‚ taking in water‚ minerals‚ and food‚ and eliminating wastes. These tasks ultimately occur at the cellular level‚ and require that molecules move through the membrane that surrounds the cell. There
