Chromatography: How can we separate a mixture? Purpose The chromatography lab is to understand how molecules with similar molecular properties can be separated with paper chromatography. These differences will be interpreted to see the distinction of separate chemical substances. Pre Lab Questions 1. Explain capillary action as it pertains to water and paper. Capillary action makes water draw up the paper. As paper absorbs water mixes with the solutions in the paper. 2. What is the

experiments were performed to a cloth dye comparison. The absorbance of Disulfonic Acid in the experimental trial was 608nm with an absorbance of 1.037 with Beer’s law the epsilon value was determined to be 22416.67m-1c-1. The percent yield of the second indigo Carmine experiment was determined to be 7.55%‚ 8.06%‚ 6.91%‚ 5.10% and 4.72%. Introduction: This is a two week experiment involving transformation of matter where we will investigate the synthesis of the dye indigo‚ which will be made‚ isolated

and the characteristic of the flow. Other than that‚ the range for laminar and turbulent flow can be calculated and the theory that Reynolds number is dimensionless can be proven. The pump is opened to let the water flow. The dye injector valve is opened to let the dye flow into the glass tube which act as an indicator to the fluid behavior either it is laminar‚ transition or turbulent. The volume of water from outlet valve need to be collected for 10 second after the fluid motion is stabilized

Speech. How to dye your own hair. At our age‚ finding that one gray hair can be quite disturbing. If you dont have any yet‚ between the stress from school and work‚ and our entry into adult hood its bound to happen. Thankfully‚ there are cosmetic products that can help us cover our evidence of old age and keep us looking young and healthy. Studies show that about 75% of americans today have dyed their hair‚ and that is including men. Today I’m going to show you how to dye your own hair‚ what

hypochlorite necessary to make a diluted food dye change to colorless in less than three minutes helps calculate the absorbance which can then be analyzed to find the pseudo rate constant and eventually leading to the rate constant and the rate law. The results show that the m and n are both 1st order which makes the overall order of the blue dye 2nd order. Results: In this experiment‚ rate laws and graphs help calculate the oxidation of food dyes by sodium hypochlorite. During the experiment the

PAPER and COLUMN CHROMATOGRAPHY REPORT 1. 2. The unknown code is an amino acid‚ Glycine. To justify the reason is because the retention factor is the same exact number as the Glycine. The data of the unknown shows everything to be exact with the data of the Glycine 3. The mobile phase is the more polar during the capillary action of the experiment. As soon as the paper touches the mobile phase‚ the solvent rises to the amino acids. This is where you can find polarity of the amino acids.

Abstract This experiment was carried out to perform staining methods on microbes‚ explain the mechanisms of staining‚ namely‚ simple staining‚ and learn how to use the microscope. The experiment setting was kept as sterile as possible when conducting the experiment. The microbes under the microscope were drawn out and labelled. In conclusion‚ different staining techniques are used to determine the presence of certain exterior structures of the bacteria like the cell envelope or just to identify
