A comparison of how each solution (salt water and alcohol) separated the pigments from each color of candy or ink type. Which solution worked better at separating each of the pigments (it may be different for different candy colors or inks), and why do you think that is?…
Chromatography is a term used to define a set of laboratory techniques for the separation of mixtures. Through Chromatography we analyzed complex mixtures. In our recent lab we analyzed complex mixtures. The purpose of this lab was to find whether the water soluble or acetone soluble liquid traveled farther. In our recent lab we measured the distance traveled by the different colored water and acetone soluble inks. W put three dots of water soluble ink on a piece of filter paper and four dots of acetone soluble ink at the other end. We then put the end of the filter paper in a small amount of distilled water in a beaker. The filter paper absorbed the water and the ink slowly spread to the top of the paper. We repeated these steps for both the water soluble and acetone soluble ink but when we did the acetone soluble ink, we placed the filter paper in an acetone-water mixture instead of just distilled water. We then recorded our results which showed that water soluble inks traveled farther than the acetone soluble inks. The results of our experiment showed how each different color of water soluble inks traveled farther than any of the acetone soluble inks.…
The resolution calculated was .778 (see calculations), which made it difficult to perceive where exactly one dye began and the other ended. Thus, when the dyes were emerging from the column, they mixed and formed a blend of the two colors to form a light purple color, which made it difficult to ascertain where the red ended and to discern where the blue section began. Thus, it was not a perfect separation as the dyes mixed when emerging.…

If I am to put a chromatography paper into a solvent, then it would separate the pigments depending on their Rf value. I think the pigments will separate in this order: Chlorophyll A, Chlorophyll B, Carotene, and Xanthophyll.…
Paper chromatography is an important separation technique that depends upon differences in how strongly the dyes are adsorbed onto the paper (stationary phase) and how soluble the dyes are in the developing solvent (mobile phase). In paper chromatography, a small amount of the mixture to be separated is placed close to the edge of a piece of paper. The edge of the paper is then immersed in a developing solution. As the developing solution ascends up the paper by capillary action, the. components of the sample are carried along at different rates. Each component of the mixture will move a definite distance on the paper in proportion to the distance that the solvent moves.…
performance. Results showed the tests printed in red ink produced significantly lower scores than the tests printed in green, blue, and black ink. This effect was especially pronounced between the green and red test results. This work suggests…
1mL of the concentrated solution was saved for TLC. The stopcock was opened and the eluent was continuously added to the top of the column until the pigment separated into three separately coloured layers. The eluent was collected at the bottom and reused to flush the column. When the first band arrived at the bottom of the column, a clean and labelled 20mL beaker collected the pigment. This was repeated for the two other layers. Once all layers were collected in 20mL beakers, they were placed on a hot plate on high for 2 minutes to concentrate.…
The mobile phase dissolved the components and carried the individual pigments though certain distances, that distance was different to each pigment and the mixture was separated into different coloured spots.…
The point of doing this project is to use paper chromatography to see which dyes are used in the coatings of your favorite colored candies. Chromatography is a technique for separating mixtures. Chromatography can be used to separate specific components from a complex mixture, based on molecular size or other chemical properties. It can also be used to identify chemicals, for example crime scene samples like blood, drugs, or explosive residue. Highly accurate chromatographic methods are used for process monitoring, for example to assure that a pharmaceutical manufacturing process is producing the desired drug compound in pure form.With colored mixtures in paper chromatography, you can see the components separate out on the paper. A mixture of various components enters a chromatography process, and the different components are flushed through the system at different rates.…

When the materials (coke,vinegar, calamnsi, milk, beer, ampalaya and distilled water) drops little amount of liquid to the blue litmus paper, it turns to color pink. Using also the same materials, drops a little amount of liquid to the pink litmus paper the color was remain the same.…
*ABSTRACT: There are many kinds of ink. In our experiment we will use Ti plant as the main component of our ink. Having two different set-ups will provide the chance to compare the colors and consistencies. Cornstarch is an efficient additive to have the right consistency of the product....Ink Made from Teabags…
