Science Fair Research Paper Chemical mixture separation of grape soda. -How can I separate color dyes in grape soda using space sand? By: Jiaqi Li Room: 8B/327 There are many different types of soda with different color. Is soda really made of natural color from fruit? Is that safe to drink? Will that kill you? So there is science behind this. The colors of the soda is made of pigments. The fruit color will make the color of the soda brighter. Column Chromatography is a new technical

Water Food Dye To being the experiment‚ you need at least 20 cups halfway filled with water and grouped in five groups of four. Place a drop of blue dye in the first cup of each group‚ red dye in the second cup in each group‚ and purple dye by mixing red and blue dye together in the third cup in each group. Leave the fourth cup of each group clear with just water. Label each cup of red dye blood type A‚ each cup of blue dye blood type B‚ each cup of purple dye blood type AB‚ and

In Chapter 3‚ Lipton explains his ideas the membrane‚ the “magical membrane” as he calls it‚ and how it controls the life of cells. He described membranes as being an intelligible life‚ comparing it to a sandwich made up of bread‚ a large hunk of butter‚ and both seedless and seeded olives‚ something you don’t find on the Subway menu. He shares about the proteins of the membranes‚ how they connect to the “mem-brain”‚ how the membranes react to their environment‚ and how people receiving diseases

electrophoresis results: a) Which solution sample contained a single dye: S1‚ S2‚ or S3? How do you know? S3 contained a single dye because it only had one band. b) The molecular weights for the dyes are 452.38 atomic units (au) for orange G‚ 669.98 au for bromophenol blue‚ and 538.62 au for xylene cyanole. How do these weights compare with your original conclusions about the weights of the dyes? Base on the order of movement of the dyes through the gel (yellow moved the farthest‚ then purple‚ then blue)

Literature According to Wikepedia Book‚ Ink is a liquid or paste that contains pigments or dyes and is used to color a surface to produce an image‚ text‚ or design. Ink is used for drawing or writing with a pen‚ brush‚ or quill. Thicker inks‚ in paste form‚ are used extensively in letterpress and lithographic printing. Ink can be a complex medium‚ composed of solvents‚ pigments‚ dyes‚ resins‚ lubricants‚ solubilizers‚ surfactants‚ particulate matter‚ fluorescers‚ and other materials. The

LABORATORY EXERCISE 8-A: Preparation of Bacterial Smear and Simple Staining I. INTRODUCTION Bacterial smears are prepared for the purpose of viewing microorganisms under the microscope. Visualization of microorganisms in the living state is very difficult‚ not just because they are minute‚ but because they are transparent and almost colorless when suspended in an aqueous medium. A bacterial smear is a dried preparation of bacterial cells on a glass slide. Smears may be made from a dry culture

affixed to the fiber‚ so that it may not be affected by washing and friction. Textile printing is a process through which a pattern‚ color‚ or combination thereof is applied to the surface of a textile. When a fabric is dyed‚ all the fibers absorb the dye and assume the designated color. With textile printing‚ however‚ only the surface fibers or specified area of the textile receives the color or pattern. As a result‚ the color is not applied uniformly but in selected regions. As a method of printing

lightstick. There need to be two chemicals that interact to release energy and also a fluorescent dye to accept this energy and convert it into light. Although there is more than one recipe for a lightstick‚ a common commercial lightstick uses a solution of hydrogen peroxide that is kept separate from a solution of a phenyl oxalate ester together with a fluorescent dye. The color of the fluorescent dye is what determines the resulting color of the lightstick when the chemical solutions are mixed. The
