Experiment On The Color Purple - 1762 Words

Section 1: Introduction and Guiding Question: In an experiment attempting to make 1-Liter (L) of Pirate-Purple (P-P) dye solution, an experimenter must first understand how the color purple was made. The color purple was created through a mixture of the two primary colors blue and red. During the pre-lab for the experiment, the experimenters were given two dyes: Blue 1 (B1) and Red 3 (R1). Using the stock dyes given, the experimenters were required to create serial dilutions of each dye. A solution was a â€Å"homogenous mixture of two or more substances,† which was necessary to know as the pre-lab of the experiment focuses on creating solutions of varying concentrations, understanding molarity, and how absorbance allows experimenters to†¦show more content†¦An analytical wavelength was the wavelength at which a color of the visible light spectrum will experience the strongest absorption, and the less diluted solutions with higher concentrations will absorb more of th e transmitted light. Once the B1 and R3 dyes have their absorbencies calculated, the experiments can then attempt to answer the guiding question, â€Å"how could you make 1-L of Pirate-Purple dye solution?† The guiding question was related to the background information because the background information was necessary to use absorbency and molarity to understand how to make 1-L of Pirate-Purple dye solution. Absorbency can be used to find molarity by using an equation for the slope of a graph made during the pre-lab which describes the relationship between concentration and absorbency, the equation was ( y=m(x)+b). In the equation, (y=absorbance), (x=moles), (m=slope), and (b=concentration). By rearranging the equation into: (x=((y-b))/m), which allows the experimenters to calculate moles from absorbency. Using the newly made equation, experimenters can use the given molar mass of B1 dye: 792.84 g/mol and the given molar mass of R3 dye: 879.83 g/mol to calculate the ratio of B1 and R3 dyes to create the three given P-P dye solutions given. The goal of the experiment was to determine the absorbency of B1 and R3 dye in each sample given P-P dyes and then by using dimensional analysis to convert absorbency into moles then into molarShow MoreRelatedThe Effects Of Color On Carbonic Acid Levels1466 Words   |  6 PagesThe effects of color on carbonic acid levels Mustafa Abdalla Alberto Moreno, D’Mario Robinson, Alexis Downey, Mong Trinh Doan Biology 1441, Section 055; Prof. Corey Roelke; October 14th, 2014. Abstract: Different colors of light affect the development of plants in different ways. The rate of photosynthesis of each plant will differ depending on the color of the light that is emitted on it. Once the carbon dioxide is produced it will react with the water in the aquatic system, thus producing carbonicRead MoreExperiment : Stroop s Stroop Effect1026 Words   |  5 Pages IB Psychology SL Internal Assessment May 2017 Word Count: Stroop Effect Abstract The aim of this experiment was to replicate the experiment Stroop (1935). This study was the basis of the Stroop effect, which says that common tasks such as identifying a color can be interfered by automated processes, such as reading.

Melting the crystals can determine the purity of the product that was made. When performing the experiment, salicylic acid will be in a flask and in a water bath. It is important that it sits in the water bath for at least eight minutes but no more than ten minutes. If it is in the water bath for more than ten minutes, the salicylic acid could decompose. The purpose of this experiment was to determine the presence of salicylic acid and starch in acetylsalicylic acid.

The Iodine test is used to detect the presence of carbohydrates. This test is used to distinguish starch (polysaccharide) from carbohydrates. Reaction between starch and Iodine produce a dark grey, black color and it means that the test is positive. A yellow color means that test is negative. But other polysaccharides may give other colors including blue or red.

Mendel did experiments on two different colored pea plants. In the first test, he mixed a purple flowered pea plant, and a white flowered pea plant. He let these plants fertilize and have off spring. These two plants were known as the Parent generation (P Generation). The offspring they produced were known as the F1 Generation. The P Generation created an F1 Generation that was all purple pea plants. Mendel then bred a new generation of pea plantsRead MoreArt And Its Effect On Society996 Words   |  4 Pagesdifferent colors in the world. There are light colors and dark colors and colors in-between.

According to Campbell, et al, in Biology: Concepts and Connections, red cabbage contains a water-soluble pigment called anthocyanin that changes color when it is mixed with an acid or a base. The pigment turns red in acidic environments with a pH less than 7 and the
