Introduction: Nails Galore asked us for help in creating a pigment that can be added to a clear lacquer, and it will eventually be used as nail polish. We were asked to make two different pigments. For our first pigment, we decided if we add nickel chloride and sodium hydroxide together, then it will produce sodium chloride and nickel hydroxide and will make blue. For our second pigment, we decided if we add cobalt (II) chloride and sodium phosphate together, then it will produce sodium chloride and cobalt phosphate and will make magenta. In multiple MSDS sheets, it provided the solubility and pigment of each chemical. Provided by the Sodium Phosphate MSDS sheet, sodium phosphate is easily soluble in water and the color appears to be colorless (Material Safety Data Sheet - ScienceLab.com). In …show more content…
If we add cobalt (II) chloride and sodium hydroxide, then it will produce sodium chloride and cobalt phosphate and create a purple color. The data we collected fully supports both hypotheses. When we mixed the reactants together, they both created the color they were expected to be and what we researched. However, the effectiveness of the nail polish wasn’t what we expected at first. First, the blue polish appeared to have little chunks of the dried precipitate on the nail. Once, it dissolved, then it was smooth for the most. When applied to the nail, it was a little rough, but once you added a second coat you could hardly tell. Second, the purple nail polish was smooth and had no chunks. But when it was applied to the nail, it seemed to be a very faint purple/magenta color. If you wanted the color to really show up, a couple coats of the polish would need to be applied. Although, it felt smooth and there was no chipping. Overall, we created two different precipitates in order for us to create two different colors of nail
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.
I am in love with the Himalayan salt bath soaps. I can 't wait to get home to try the products.” Katie W. Anytime I have had a misstep and ruined a color, they have fixed it. I get acrylic nails applied.
Double Replacement Lab Report Date Completed: October 8, 2015 Objective To analyze and determine if a chemical reaction occurred between two compounds using the concepts we learned in class. Also, if the chemical reaction occurred, to determine if it formed a precipitate or gas. Safety General Safety Precautions: Do not touch the chemicals Use of gloves and coats are recommended, use of goggles should be required Keep the work area clean Dispose of the chemicals properly, DO NOT dispose them in the sink Clean up your work station Wash your hand before and after the lab Make sure all chemicals are labeled correctly NEVER return chemicals to reagent bottles Use the wafting technique to smell the chemical Clean up spills immediately
Avocados that are bought at the store are not all authentic to California, because some are originally from South Central Mexico. Such as the advertisement of the avocado, the speaker of a story tries to convey a story of originality that would go undoubted by the reader. An autobiography also can convey a truth-like story, but there is still uncertainty to know if the events told are true, which would cause the story to be a farce. A story told in the first person point of view creates a relationship with the writer and reader, such as the choice to either spectate or have a role in the story. A narrative told with an autobiographical style can lead the audience to take the place of the narrator of the story.
After a while, a brownish color substance started to form on the three iron nails. We predicted that the brown substance on the nails is copper because the reaction of copper(II) chloride with iron is a single displacement reaction, so copper would be produced. 0.48 grams of iron was used in the reaction because 2.73 grams subtracted by 2.25 grams is 0.48 grams. The 0.48 grams of iron had to be used in the reaction with copper(II) chloride in order to produce copper, according to the reaction equation: CuCl2+FeFeCl2+Cu. 0.52 grams of copper was produced after pouring out the copper(II) chloride solution and the three iron

And women all over the world started to take notice. These nails can be glued to your nails and come in different shapes and colors. Some even put Rhinestones on them to make different designs. Some use glitter on them and some use different color tips and
These color changes indicate a chemical change, which show that a reaction had occurred. In the first step when o-vanillin and p-toludine, imine was formed. The color change from green to orange suggests that imine appears as orange colored. In the second step, the addition of sodium borohydride reduced the imine into another derivative, which was yellowish lime color. The solution turned clear when acids and anhydrides was added, which indicated the precipitate were dissolved.
Later on the color changed to green, which indicated the pH was 8.0. Then when we tested the pH with the pH strips they both showed the pH as being 5.0. After that, we added HCl or stomach acid and both drugs dissolved and were soluble. We tested the pH and it dropped to 1.0. They both turned a brownish-yellow when the iron nitrate was added and no other pain reliever or antacid looked like those two.
Abstract: The purpose of this experiment was to identify given Unknown White Compound by conducting various test and learning how to use lab techniques. Tests that are used during this experiment were a flame test, ion test, pH test, and conductivity test. The results drawn from these tests confirmed the identity of the Unknown White Compound to be sodium acetate (NaC2H3O2) because there were no presence of ions and sodium has a strong persistent orange color. The compound then will be synthesized with the compounds Na2CO3 and HC2H3O2 to find percent yield.
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.
“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.
A few of the polishes I used are: Talia is a teal crème from the Zoya 2015 Island Fun collection. Flying Dragon is from China Glazes neon 2008 collection called Ink. It 's not meant to be a matte, but the finish is rough similar to a matte polish. Flying Dragon is fuchsia with a hint of purple. Lightning, by Sally Hansen, is a bright sunny yellow cream.
Jaspreet Singh Professor Paratore Biology 1 November 1, 2014 Spectrophotometry Identifying Solutes and Determining Their Concentration Statement of the Exercise or of the Problem The purpose of the lab experiment was to attain the following objectives: • Learning to Operate the Spectrophotometer • Construct absorption spectra for cobalt chloride and chlorophyll. Hypothesis If greater and higher concentrations of cobalt chloride are added to each solution then greater amounts of light would be absorbed by each solution. Thus a liner relationship will result in which the absorbance of a substance would be proportional to its concentration, which will be depicted, in a linear graph.
After I explained everything to them Nick took me back to the computer where he was making the clear coat. At this point I was just watching what he was doing and trying to see how he was making the clear coat how he knew how much to make. I asked him how he went through this process and he explained to me that you enter in what you are making and it will tell you the identification number on the can then you look for the gallon of product that you need. Then you grab a small container that connects to the spray gun, and then set it on the scale and pour in the different combinations of paint materials. To make a clear coat you combine three different materials to make sure it stays on.
