For this lab, zeolite and magnetized zeolite were synthesized and compared with charcoal to find out with would be the most effective in the sequestering of Procion Red dye. Finding the concentration and absorbance of each zeolite, magnetized zeolite, and charcoal, along with a calibration curve, the best adsorbent is determined. Charcoal was the overall best sequestration of the Procion Red dye, since the adsorbent was highest compared to the others. Introduction Pollution has increased in the environment over the years, so the purpose of this experiment is to find the best adsorbent of chemicals to reduce the pollution.
Step 2: Mix both test tubes , shake gently and time the reaction. Step 3: The same step as procedure 1, and step 3 which is to record the observed color step 4: use the palette/color chart to help you identify the observations you make. Safety precautions: Pull your hair back Safety eye goggles Closed toe

While performing the slime lab, we were trying to find the effect of borax on glue and water. We mixed glue and water together and added small amounts of borax water to it. We wanted to find the difference in stretchiness with different amounts of borax. After adding the borax, we measured how far the slime could stretch. We hypothesized that the slime would stretch farther when more borax was added.
Second, 10.00 ml of the blue dye was poured into the 100.0 ml beaker and stirred for 2 – 3 seconds. The time taken by the solution to turn to colorless was measured with the aid of a stopwatch. The aim of this exercise was to determine the mixture that turned colorless in 15 minutes time. The data was recorded as shown in Table 2. Absorbance versus Time Measurements:
After analysis, we have determined Red No.3 dye is the most polar of the three dyes. This is due to the fact that this dye consistently had the lowest Rfvalues. Conversely, the most nonpolar of the solutes was Green No.3 as it had the greatest Rfvalues. This conclusion coincides with the theory that the most polar solute will have the lowest Rf values due to its attraction between the polar cellulose fibers. Further, the Green No.3 dye is the most nonpolar due to its high Rfvalues which were the result of its lack of attraction to the polar cellulose fibers.
Purpose The purpose of this project is to test common sports drinks for their electrolyte content and compare the results to the electrolyte content in common fruit juices. Hypothesis If fruit juices were to be compared to sports drinks for electrolyte content, then orange juice would contain the most electrolytes. Materials orange juice sports drink (Gatorade, PowerAde, Generic sports drink)
Through observation, it was noticed that certain panfish, living in murky water, were darker in color than other fish living in clear, light colored water. To test this observation, goldfish were placed in two containers, one containing blue food coloring and one without color. The fish were given five days in five drops of food coloring and five more days in ten drops of food coloring. At each increment, a photograph was taken of every individual fish and the orange pigmentation below the dorsal fin was compared to an interactive online color spectrum chart; the closest shade of orange was documented by wavelength. The fish in the food coloring expressed a slightly higher wavelength than those in the control water.
Morgan Spurlock did this experiment because two overweight girls were sewing the Mcdonald 's fast food restaurant for making them obese. The girls lost the case because they couldn’t prove that Mcdonald’s food made them obese. Morgan did this experiment to prove if Mcdonald’s food did have an effect on your health after eating only Mcdonald 's. During the experiment Morgan had to follow rules and guidelines. Rule #1 is that when only when asked Morgan must eat Super Sized Meals.
Hypothesis For this lab, we expect the polar pigments will have the largest Rf value whereas the non-polar pigments will
“In 1775, more than a million pounds of indigo was exported from South Carolina to England” (Indigo’s Political, Economic, Cultural History 1). This massive amount of dye being traded was due to many factors that made it nearly the perfect trade commodity. The process of indigo dye being made by slaves in South Carolina in the 1700s is shown very well in the book Someone Knows My Name by Lawrence Hill. The production of this indigo dye has an extensive history of being extremely arduous to produce naturally, but results in a compact substance that will last a long period of time and be very valuable.
The ammonia: 1-butanol (1:1) solvent was the appropriate solvent to use for the column chromatography of food dye because it exhibited the properties of a good solvent system. A total 8 colored eluents were collected. The eluents had colors of pink, dark red, dark blue, dark green, light green, yellow, orange and light yellow respectively and
2-Dark Reaction Three ecological varients that have different carbon dioxide incorporation mechanism have evolved during evolution that are C3, C4 and CAM plants. There is no net carbon dioxide assimilation until carbon dioxide during respiration is fully compensated by photosynthetic carbon dioxide fixation. The supply of carbon dioxide to the chloroplast occurs through diffusion process. C3 Plants:
Many people ask "is dyeing your hair bad?" Hair dye is bad because it causes hair damage, it could turn out to be the wrong color, dye fades over time, and it costs a lot. Dyeing your hair can cause damage and damage from bleach includes dry, brittle, inelastic hair, and hair that is more prone to breakage and split endsIt can be permanently damaged so if someone wants to dye their hair they have to have strong hair. To get certain colors you might have to bleach and tone it if you have dark hair and bleaching hair is the main cause of hair damage bleach kills your hair.
A reddish purple shade is the desired colour outcome of this study which contains anthocynanins (ACNs) which are water-soluble plants pigments responsible for the blue, purple, and red colour of many plant tissues (Beecher et. al.,
