The purpose of this lab is to determine which color travels further up on the strip of paper due to the reaction of the different solvents (1% salt solution and alcohol).…
In order to experiment with distinct components of a mixture, they must be first separated so they can be observed individually. This is accomplished in this lab by the technique called thin layer chromatography (TLC). TLC involves a stationary phase, which the TLC plates as well as a mobile phase, which could be one of two solvents used: ethanol-acetone for TLC. Dyes in a sample separate consequently because of their unique polarities. As a result, nonpolar substances travel further than polar substances in this process. The separation of a mixture into its components by TLC transpires because the distinctive components of a mixture interact to different extents with the stationary and mobile phases.…

(As The Editors Of Encyclopædia Britannica say “Paper chromatography, technique for separating dissolved chemical substances by taking advantage of their different rates of migration across sheets of paper. The method consists of applying the test solution or sample as a spot near one corner of a sheet of filter paper. The paper is initially impregnated with some suitable solvent to create a stationary liquid phase. An edge of the paper close to the spot is then immersed in another solvent in which the components of the mixture are soluble in varying degrees. The solvent penetrates the paper by capillary action and, in passing over the sample spot, carries along with it the various components of the sample.”) they explain what and how paper chromatography is used for. They all have to do with colors. Having to do with finding the real dyes in colors. (As Science Buddies explain “What color is black ink? Sometimes things are not just what we think they are. Often things can be broken down into component parts. One way to find out it to use a common chemistry technique called chromatography.”) This quote explains that there can be many object in just one object, just like paper chromatography. The paper chromatography experiment it tested to see what kind of dyes are just in one…

The group will conduct the study because the group noticed that teabag extract is dark in colour and it can be use to make ink, and also the group noticed that teabags are made from natural resources. Some kinds of teas are made out of a plant known as Camellis Sinensis. This plant is native to mainland China, but it is today cultivated across the world specially in tropical regions. Due to the chlorophylls and other pigments in the leaves, the extract commonly appears with a brown colour.…

*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…
Banana is a tropical plant classified as annual and it produces very abundantly. It is cultivated throughout the country especially in the provinces. “The king of the fruits”, mango fruit is one of the most popular, nutritionally rich fruit with unique flavor, fragrance, taste, and health promoting qualities making it a common ingredient in new functional foods often called “super fruits”. Banana is one of the delicious tropical seasonal fruit and believed to be originated in the sub-Himalayan plains of Indian subcontinent. Botanically, this exotic fruit belongs to the family of Anacardiaceous, a family that also includes numerous species of tropical fruiting trees. The focus of the researcher is not the fruit but the Banana sap produces stain on the clothes and such stain is difficult to remove. This observation gave the researcher the idea of using the mango sap as substrate for pen’s ink with the thinking that the banana sap could stabilize ink. The purpose of this study is to utilize the banana sap as an alternative ingredient which very abundant source of quality ink. In addition, it maximizes the use of banana which grows abundantly in any rural areas and that it minimize the problem on waste disposal. The researcher also considers the challenge of doing this project being the first to do this study. The excitement as to the output will work or not is another point of consideration.…

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 components of inks serve many purposes; the ink’s carrier, colorants, and other additives affect the flow and thickness of the ink and its appearance when dry.…
