Permanent Marker

In the Dyes and Crimes laboratory experiment, the phosphorescence, fluorescence, and chemiluminescence properties i.e. traits of several chemicals were examined using (UV) Ultraviolet lamp. Observations on color, intensity, duration of glow, etc. were analyzed to determine the traits of the several chemicals. Correspondingly, the author of the unsigned note was determined through ink extraction, (TLC) Thin Layer Chromatography, (UV-Vis) Ultraviolet-visible spectroscopy along with the Rf values for of each individual sample of ink compared to the unknown: the ink of the author on the unsigned note. Phosphorescence substances

Some substances that can be used to remove lipstick is make up remover, baby oil and cleansing cream.

Purpose: The purpose of this lab is to identify the dyes present in the different mixtures. Introduction: This lab uses chromatography to determine the dyes present. It is also used to identify the different intermolecular forces each solution and dye has.

Is a marker’s ink a mixture or pure substance? If a teacher signs their name, then you can use chromatography to determine if the signature has been altered. A marker’s ink is a mixture. In this lab, we started by gathering our equipment and materials.

Once the application of the spinach extract was finished, acetone, the solvent, was poured into the beaker. Then the cylinder was placed into the beaker to absorb the solvent with a jar top placed on top of it to hold it in place. The chromatography cylinder stayed in the beaker until the pigments in the spinach extract had been separated into different colors and was about 4-5 cm from the top of the paper. After this, the chromatography cylinder was removed to dry for the different pigments could be observed.<p>

Ink can be defined as a pigmented substance which can be used to create markings on a surface; however, over the course of history ink has been composed of different materials. The earliest form of ink known to historians, Indian Ink, was created around 2500 BC by the Chinese. This ink was a mixture of soot from pine smoke, lamp oil from animal skins, and musk. Scholars and scribes used this it to record information such as farm accounts, religious texts, and possessions and the people who owned them. Further down the timeline, Europeans created Iron Gall Ink from crushed gall nuts, iron or copper salt, and comarabic (which held the mixture together). Because of its durable nature, people such as Bach, Leonardo Da Vinci, and Van Gogh used it

The next step was to place the strip of chromatography paper on a paper towel. Then dip a capillary tube into the plant pigment extract (spinach pigment extract) provided by the teacher. The tube will fill on its own. We applied the extract to the pencil line on the paper, blew the strip dry, and repeated it three to four times until the line on the paper is a dark

Alcohol. You may see a lot of types of this in varying percentages. Whatever kind you would like to choose, it always does the same superb job in removing what you wanted to come off so badly. It could serve as a solution you could use in solving the dilemma you have in making the label come off from the thing it sticks on.

The core of a pencil, confusingly named the “lead”, is formed from a naturally occurring element known as graphite, discovered in the Lake District of England in the early 1500s. Graphite is not the first example of an element hewn from the ground and used as a mark making tool - this process dates back to the very first examples of human art seen in prehistoric cave paintings which were created using both charcoal and chalk in the era between 40,000 and 10,000 BC. These substances were ground and mixed into a paste with either saliva or animal fats and smeared onto the porous cave walls. So important were these prehistoric paints that the painters travelled far and wide to obtain the pigments.

Often, people must choose between living in extreme, and focusing on a balanced life. Such is the case in the Greek tragedy Antigone, where a father has told his boys to live in moderation when he gives up his throne. While exploring the tragedy Antigone, Sophocles develops the theme of living in moderation by creating conflicts such as Polyneices and Eteocles battling for their lives, Ismene struggling with her fears and Creon struggling with his pride. At first, two brothers Eteocles and Polyneices combat against each other over the throne of Thebes. When the father of Etecoles and Polyneices, Oedipus died, he gave the throne to Etecoles who was ordered to share the throne with his brother, Polyneices.

Aim The aim of this experiment was to separate the mixture of the indicator dyes correctly using thin layer chromatography and to gain a basic understanding as to why the dyes separate out the way they do. Abstract This report was based on separating a mixture of indicators; Phenol red, Cresol red and Bromophenol blue using thin layer chromatography using propanol and ammonia as solvents.

You must, however, use acetone-based remover. Women who have acrylic tips put on their nails use a gentler, non-acetone formula on their nails to avoid damaging them. This type of remover doesn't work on dry erase marker. Check the bottle and verify that the nail polish you're using contains acetone. If it does, you're in business.

Age-graded are those things that influences within our lives that are correlated with chronological age. For example in the case study it states that lots of Kane’s mates have parents that buy them booze as they would be unable to buy it as they are too young. History-graded are influences within our life that correlate with historical time and are generally experienced by the majority of a culture For example in the case study - Kane sat his learner licence when he was 16 years old, which is the age that all young people are able to sit their learner licence in New Zealand. Non-normative are experiences that we generally do have, but if we do it will have a profound impact on us. In the case study Kane attended two of his friend’s funerals,
