    Skin Dye made the dye bath turn into a light yellow color; However‚ this color did not look like the color of the onion skin. The Carrot Tops Dye had not changed the color of the dyed bath but stayed clear throughout the experiment. On the other hand‚ in Picture 2‚ the Zinger tea and Chamomile tea had deeper color in their dyed baths: orange and dark red‚ respectively. None of the yarn samples were the same color as the dyed baths‚ except for the yarn sample that was dyed with the onion dye. As shown

    Gas chromatography (GC) is a chromatography technique where the separation of individual components (analytes) from a sample relies on their differing distribution between a mobile and stationary phase. The mobile phase carries the analytes through the stationary phase. In GC‚ it’s an inert gas (usually helium or nitrogen). The gas must be inert‚ so it won’t react with the sample to give a false reading. The stationary phase is a substance fixed in place to which the sample adsorbs because

    understand that because substances have different properties‚ such as mass‚ that can be separated by chromatography. In our experiment‚ we chose 4 different color source to separate in water. We made sure that all the sources were water soluble because only polar substances will dissolve in water. We chose a black wet-erase marker‚ a red marker‚ a green marker‚ and mixed food coloring to test. The chromatography paper was split into 4 sections‚ about 2 cm above the bottom edge and evenly spaced out. Each

    Data and Conclusions: The purpose of this experiment was to learn how to use distillation and gas chromatography to separate and identify different compounds from a given mixture. There are several kinds of distillation methods. However‚ the method that we used in this experiment was fractional distillation. This method is used when trying to separate two different volatile compounds whose boiling points differ by 40-50°C or more. If the boiling points are too close‚ this method

    their mouths and a happy‚ satisfied grin on their faces. The reason for conducting the research is to know how the colors of our favorite candy-coated sugary rewards came to be and that method of knowing is what we call “Candy Crhomatography”. Chromatography by definition according to Webster’s dictionary means “ a method for separating the constituents of a solution (gas or liquid) by exploiting the different bonding properties of different molecules”. In this case‚ the molecules being broken down

    Abstract Finding the melting point of an organic substance is a practical and efficient way for scientists to identify an unknown substance or determine a known substance’s level of purity. When organic substances are mixed together in varying degrees they take on a melting characteristic that is lower and broader than in its pure form. This property was manipulated in the lab to observe the various melting points of Naphthalene and Biphenyl when the percentage of composition was altered. A

    Candy chromatography My experiment is called candy chromatography. This project is mainly about the colors that are mixed with other colors to make candy markers Koolaid and much more. I think that only the color of the candy is going to show up on the coffee paper. I think that threw the entire experiment the color in the candy is going to show up the entire time. I think this is going to happen because most of the colors are solid colors. The material and equipment used was a sample of candy
