Course Instructor: Cynthia Spencer Purpose
The purpose of this experiment was to construct a Beer’s Law Plot, determine the concentration of a sample using the Beer’s law plot, and to determine the concentration of Blue Dye #1 in a commercial product using visual Colorimetry. Procedure
This lab consisted of calculating %T of given data and constructing a Beer’s Law plow. Secondly, …show more content…
In other words, the M concentration must be between 2.85 x 10-4 M and 3.15 x 10-4 M. Does Batch 021015 meets the legal requirements?

Since, average concentration of M in the batch Q is 2.16 x 10^-4 M where as the requirement is between 2.85 x 10-4 M and 3.15 x 10-4 M. Therefore, the batch does not need legal requirement.

Exercise 2 The concentration of Blue Dye #1 found in the Gatorade Cool Blue was determined to be 1.8x10^-4.
Conclusions
This experiment was designed to explore the methodologies behind determining the concentration of compounds using both qualitative and quantitative data. The conclusions that can be drawn from Experiment 2 and 3 are that the company reported concentrations in sample Q021015 are not accurate and based upon the sampling data the %error of the samples are 38.89%, which do not meet legal requirements. Through visual colorimetry it was determined that the concentration of Blue Dye #1 is 1.8x10^-4 moles. This experiment was a success, due to the fact that all objectives were met and satisfactory understanding of the materials was

    Nahco3 Hydrochloric Acid

    From my results I can see that the accurate result was 0.98 and our estimated was 0.1M but I rounded up my answer to 1 decimal places to see so there was not that much of a difference. Overall my experiment went well because I have followed instruction and I archived my hypothesis because I calculate that the chemical will have more concentration because it is a hydrochloric acid which will react with a methyl orange indicator solution and cause colour change from yellow to pink in my experiment I could clearly see the change of the colour. Form my results table I can see that my results were close to 0.1M which means that I have used the accurate amount of standard solution in my experiment If I was to improve my experiment I could attempt to read the burette to the bottom or top of the meniscus by doing this it might give me accurate results for my experiment. Another way of improving my experiment could be that I use volumetric pipettes for measuring.…

    To complete this lab, I first mixed the solvent solution consisting of the proper ratio of water, salt, and isopropyl alcohol in a Pyrex measuring cup. I then prepared my chromatography papers for 2 trials by drawing, with a pencil, the appropriate lines and labels. Using a toothpick, I added the color to the paper, and then repeated until the color was strong. I repeated this step several more times for the M&Ms as the color solution was not as strong as the food dyes. After the dyes were dry, I rolled the paper and added it to the pie plate, which contained a small amount of the prepared solvent. I then waited for the solution to…

    Red 40 Lab

    Determining Red 40 Concentrations Using Absorption with Beer’s Law Introduction I like color and enjoyed learning about wavelengths and the spectrum of light, so I considered incorporating something related to that into my Internal Assessment. We also had just used concentrations in our Group 4 Project, so when I found an experiment that dealt with both of these I thought it was a great idea. This experiment is not completely original; the basic concept has been used multiple times. It uses Beer’s Law: · A is light absorbance · is “molar absorptivity with units of L mol-1 cm-1” · l is the length of the cuvette in centimeters · c is the concentration of the solution in mol L-1…

    The initial step to determine the concentration of the dyes previously found was to prepare a set of serial dilutions at 20%/40%/60%/80%/100% dye concentration. To prepare the 20% dilution 1mL of red 40/blue 1 was combined with 4mL of DI water. This method was used to produce the remaining dilutions with 2mL/3mL, 3mL/2mL, 4mL/1mL, and 5mL/0mL (mL dye / mL DI water). Each of the previous dilutions was tested in the spectrometer and data was recorded. Using the data obtained two Beer Law plots were plotted for both dyes and trendlines were added. The slope of the trendline was found and used to calculate the actual (mol/L) and percent concentrations…

    Spectrophotometry

    Spectrophotometry was used in the lab to determine whether non-magnetized zeolite, magnetized zeolite, or charcoal was the more effective sequestration agent for Procion Red Dye. A calibration curve was created with the known concentrations and the absorbances of the Procion Red Dye dilutions at λmax. The slope of the calibration curve was used to determine the concentration of the analytes. As a result, charcoal was shown to be the more effective sequestration agent.…

    In this exercise we will separate food dyes from a variety of sources. We will first gather data on known dyes where we know how many substances make up the dye. Then we will collect data on some samples where we do not know the make-up. We will compare our known dyes with our unknown samples and be able to make a determination of which dyes are in our unknown samples.…

    Pink Lemonade Experiment

    ust imagine drinking a nice cold Minute Maid Pink Lemonade on a hot day, or a cold Red Powerade after a long hard practice. The cold refreshing drink rushes through your body and quenches your thirst. However, do you know what you are actually drinking, and how much of that drink is contaminated with dye? In this experiment, with the use of a spectrophotometer, the amount of concentrated dye in three drinks will be tested. First, the dye itself will be examined to see what the optimal wavelength and absorbance will be when created in a serial solution. Red Dye 40 was the prime object that will be studied in this lab because it is one of the most common dyes in every day drinks. Before performing any experiment though, it is important to understand…

    Natural pH indicator

    Title of this experiment is the acid-base indicator from natural dyes. This experiment is to investigate the colour variation of solution extracted from pigment of vegetable and fruit skin according to pH value and to deduce the ability of the extraction to act as an indicator in titration. The problem statement of this experiment is how does the colour of solution extracted from pigment of vegetable and fruit varies according to pH value of universal indicator and can it be used as an indicator in a titration. Method that have been used is measuring the pH and juices extraction. Household and laboratory item such as soap, concentrated sulphuric acid are tested with universal indicator to estimate their pH. The juice is then sieved and is added to respective test tube to observe the colour change. The materials that have been used are red apple skin, red cabbage and tomato. As for tomato,there is not much changes as it is colourless from pH 1-7 and become yellow from pH 8-13. Red cabbage shows a variation of colour change. It changes from red in acidic to pink in neutral and greenish yellow in alkaline medium. Red apple skin changes from red in acidic medium to pink in neutral and yellow in alkaline medium. As a conclusion, the colour changes are almost the same as the pH chart inserted in result section.…
