HYPOTHESIS: Once the dye hits the water, the dye molecules will move faster and uniformly dispersing in the hottest water first.

PURPOSE: The purpose of this experiment is to improve my ability to observe an experiment. In addition, it will help aid me in making proper observations while also drawing conclusions in Kinetic Molecular Theory.

RAW MATERIALS:
Clover Valley food color and egg dye blue food coloring contains FD&C Blue #1 https://pubchem.ncbi.nlm.nih.gov/compound/Acid_Blue_9#section=Top Chemical Name: BRILLIANT BLUE FCF Molecular Formula: C37H34N2Na2O9S3 Substance Registry: FDa UNII Chemical Names/Synonyms: 1. Acid blue 9, 2. blue 4, 3. blue no. 1, 4. brilliant blue, 5. brilliant blue A1 (3:1) salt, 6. brilliant blue diammonium salt, 7. brilliant blue dipotassium salt, 8. brilliant blue FCF, 9. brilliant blue FCF, diammonium salt, 10. brilliant blue potassium, sodium …show more content…

The dye molecule dispersed the way it did based on the temperature of water. Warmer water causes the molecules to disperse faster than colder water. In addition, the atoms vibrate and bounce faster the hotter the water is, all ending in a uniform solution.

Do you believe you would observe the same results if you changed the food coloring? Why or why not?

I believe the process would be the same in that hot water has a faster flow rate causing the substance to disperse faster. However, depending on how dense each substance is will determine how long it actually takes to disperse.

Do you believe you would see the same results if you used a different solvent life rubbing alcohol?
I believe the results will still be that of diffusion and dispersion, however, the time to completely diffuse will be different because each solvent has a different density. The heavier a solvent is, the longer diffusion takes.

Why must you wait for the water to be

Then the scientist will observe the different rates of reaction with temperature. The Boltzmann distribution of law, indicates that high temperature makes molecules gain high energy contents (pubs.acs.org/doi/abs/10.1021/ja). In order to measure the reaction rate, the scientists must use the same volume of water at three different starting temperatures: hot tap

That mixture was then filtered through a coffee filter. Nine test tubes were prepared in order to perform this dye coupled reaction. One contained 5.0ml of the potato and pH buffer mixture, 2.0 ml of hydrogen peroxide, and 1.0 of guaiacol to serve as a blank for the spectrophotometer. Four test tubes were filled with 2.0 ml of hydrogen peroxide and 1.0 ml of guaiacol, used for measurement by the spectrophotometer, each. The last four were filled with 4.0 ml of the potato and pH buffer mixture and 1.0 ml of peroxidase.

In the first part of the experiment, Part A, the standard solutions were prepared. As a whole, the experiment was conducted by four people, however, for Part A, the group was split in two to prepare the two different solutions. Calibrations curves were created for the standard solutions of both Red 40 and Blue 1. Each solution was treated with a serial 2-fold dilution to gain different concentrations of each solution.

Our hypothesis was partially correct, the property changing substances did have the weakest coherency with the lowest drop counts of 23(carbonated), and 14(soap), and pure water did have the strongest bond. What we also found was the the salt also dampened the liquid’s ability to hold onto a penny in large volumes, as all the different salts had a drop average of 24(28x2 & 16), five less than Tap water’s drop count (30). This led us to conclude that pure water has the strongest bond and that all foreign materials weaken the coherency of water. This evidence has led me to believe that similar substances are attracted and are more coherent towards themselves, in this case the water pieces get separated and generally less connected on a really small level due to the obstruction of foreign objects, this is why the different salts perform better than the huge air bubbles or the slippery properties of soap since the latter is more obstructive and the former dissolves with the water and blocks less. When studying a few other groups’ conclusions and data we did indeed find differences: some groups had differing data where a solution had better coherence than water itself which led to differing conclusions.

INTRODUCTION: In this experiment I was testing for antimicrobial sensitivity of Staphylococcus epidermidis by using the Kirby-Bauer Diffusion test. The three antibiotics utilized in this lab were: gentamicin, novobiocin, and penicillin. I determined the effectiveness of the antibiotic by observing and measuring the zone of inhibition for each antibiotic.

When we collected liquid from our distillation separation method, liquids #5 and #4 came out clear (without the food coloring). We believe solid #6 is what made our sludge purple. The density of food coloring is the same as water: 1 gram per square millimeter, our density was very close to this it was 0.51g/ cm3 and we could have made mistakes when reading the graduated cylinder.

Introduction The intent of this experiment is to understand how hot and cold water interact with each other by combining clear hot water and black ice cold water. I hope to learn more about how hot and cold water interact with each other. As of now, I know that cold water is denser than hot water. Knowing this I formed my hypothesis.

What is the effect of surface area to volume ratio on the rate of diffusion of the colour from the agar jelly cube? INTRODUCTION: Diffusion is the movement of spreading particles from high concentration to low concentration in an environment such as a cell. This major procedure is used in cells to source them with nutrients, water, oxygen, and to transport unwanted wastes such as carbon dioxide out of the cell or to different cellular organelles.

Use these results to determine the product concentration, using Beer-Lambert’s Law: A= ɛCl (where A is the absorbance, ɛ is the molar absorptivity, C is the product concentration and l is the length of solution that the light passes through). Calculate the product concentrations at every minute for 10 minutes for all 7 of the test tubes using Beer-Lambert’s Law. Plot a graph of product concentration vs. time and then use the gradients of the 7 test tubes to determine the velocities of the reaction. After calculating the velocities, plot a Michaelis-Menten graph of velocity vs. substrate concentration.

The first synthetic dye, Mauveine, was accidentally discovered by William Henry Perkin in 1856 while he was looking for a cure for malaria. Different dyes are made of different dye molecules. Dyes have colour because they absorb light in the visible spectrum (400–700 nm), have at least one chromophore, have a conjugated system (a structure with alternating double and single bonds), and exhibit resonance

In relation to a previous experiment in which the students determined the boiling points of two liquids, it was deduced that the boiling point of [propyl and methyl] alcohol was estimated to be around 80oC. According to numerous sources, ethanol boils (and consequently evaporates) at around 78.5oC[7] a much lower temperature compared to the alcoholic beverage’s other ingredients—water, for example, boils at precisely 100oC. It is immensely possible that because of this, ethanol is isolated from the beverage sooner than said beverage’s other components. Perhaps, if the students worked within
