Experiment 3 Liquid-Liquid Extraction Discussion The success of extracting each compound out of the solution can be seen in the IR graphs for each substance. For ethyl 4-aminobenzoate‚ the N-H‚ C=O and C-O are distinguishable in their proper wavenumber positions. The amino N-H stretch was found between 3224 cm-1 and 3423 cm-1. The C=O was found at 1681 cm-1 and the C-O was at 1280 cm-1. The IR for benzoic acid also displays its significant bonds‚ O-H and C=O. The O-H was between 2566 and

Part A: Diffusion on a liquid in a liquid. I did an experiment with three different glasses of tap water from the faucet. All three cups measured the same which happened to be 13 cm from the top of the cup to the bottom of the cup. I let the water settle‚ and sit for about an hour so the temperature was the same for all three cups. I then placed one drop of food coloring into the first glass and waited for the coloring to reach the bottom. I calculated 93 seconds. I then went to the second glass

Experiment 5 Analysis of Analgesic Tablet by High Performance Liquid Chromatography Abstract An unknown sample‚ 529‚ was tested using high performance liquid chromatography to detect the concentrations of acetaminophen‚ aspirin‚ and caffeine respectively. There was found to be 4.03±0.144mg/100mL of acetaminophen‚ 11.5±0.185mg/100mL of aspirin‚ and 4.89±0.185mg/100mL of caffeine. Based on accepted values‚ the maximum daily amounts of each compound are 4000mg of acetaminophen

Now it can act more like the skin of a balloon‚ stretching out nice and thin‚ trapping air inside of the bubble like a liquid balloon. What do you need to make a good bubble solution at home? The basic ingredients are water and detergent. In this experiment‚ you will add glycerin or corn syrup to see if they can help you make better bubbles. Which solution will make the

Materials: pipette‚ liquid soap‚ water‚ beakers‚ penny‚ graduated cylinder‚ paper towels. Procedure: 1. I received a beaker filled with tap water. 2. I took a pipette and filled it upwith water from the beaker. 3. I began to add drops of water to a penny‚ which was headsup

Calculating the Density of Liquids II. Purpose/Background: The purpose if this lab was to determine the density of water and an unknown liquid. Density is defined as the mass of a substance divided by its volume. It is an intrinsive property of matter and is used to specifically characterize substances. III. Procedure: 1.We massed an empty 10mL graduated cylinder to the nearest .01g. 2.Then‚ we filled the graduated cylinder with 4.0-5.0 mL of distilled water‚ 3.massed it to the nearest 0.1

Lab report: Viscosity of Liquids Introduction This experiment focuses on measurements of different trials of various concentrations. The collected data is used to compare and contrast to the ideal binary solutions and their components. The Ostwald viscometer is a useful laboratory equipment to measure the viscosities of many binary solutions. Background Molecules have the ability to slide around each other‚ result in a flow. Such a flow has a resistance called viscosity. Microscopically
