How permanent is a permanent marker? People are always getting dirty by accident or on purpose. Permanent Marker stains are difficult to remove if you don’t know which solvents to use. Many people use different household items to remove the stains. My hypothesis was if I were to dab the area where the permanent marker is with rubbing alcohol, then the rubbing alcohol will remove the ink better than the other solvents. This experiment was supposed to prove if vinegar, rubbing alcohol, nail polish
compound that is used often is Acetone, it can be used many different ways for a variety of different things. While, it is an important chemical that can be helpful, it can also be dangerous. Acetone (propanone) can also be identified a couple different ways including, C3H6O or CH3-CO-CH3 or CH3COCH3. A balanced equation of acetone combustion and is common in everyday life is
Nail polish remover: with or without acetone? As a chemist I work almost daily in the laboratory with acetone, but in everyday life, many are unsure whether the acetone is harmful in the nail varnish remover. That is why today I want to explain exactly what a nail polish remover actually consists and what it has with the acetone on itself. What ingredients do I find in nail polish remover? Ethyl acetate (ethyl acetate): as a good solvent, is an important component of nail polish remover and helps
Fingernail polish remover has been around for quite sometime now, some may even say a hundred years (S). It “may lose potency”, but it may never go a bad (Dodd). Remover was invented by Michelle Menard and has continued to be a constant use in everyday lives (S). There are all different kinds of ingredients in fingernail polish remover depending on the brand, but the main ingredient for most fingernail polish removers is either the combination of ethyl acetate and isopropyl alcohol or ethyl acetate
algae was Coleus sp. A different procedure was conducted for extracting pigments from the different colors of algae. The red algae were grinded using both water and 90% acetone in order to get all the pigments out. The green algae was crushed in 90% acetone only, and the brown algae was placed in DMSO and then in 90% acetone. We used the same technique for Coleus sp. was as we did for the red algae. A spectrophotometric analysis was taken of each of the seven total samples. Polysiphonia
Grease spot test is one of the tests for lipid identification. The working principle is that most lipid or grease are non-volatile due to their high boiling point. In room temperature, the water spot will disappear because water can absorb enough heat from the surrounding air and evaporated. But, the lipid spot can never absorb enough heat to evaporate and hence the lipid will stuck inside the paper sheet. Thus, lipid diffracts the light ray so that light can pass from one side of the paper to another

Cut up a handful of leaves (reasonably small handful) with the scissors and place in the mortar. 2. Add half a spatula (no more) of sand into the mortar with the leaves, and then add 5ml acetone with the pipette into the mortar as well. 3. Carefully grind the leaves, acetone and sand together in
TLC analysis by leaving the insoluble properties behind. Each step serves a purpose in doing so, for example, the spinach is blended into a puree in order facilitate the centrifuge process. 75/25 hexane/acetone solution is used in the blending process because hexane alone is not enough and acetone alone is miscible in water. Anhydrous sodium sulfate is used to dry the organic solution after it has been through the centrifuge tube and separated into a test tube. The purpose of the alumina column is
understand the relationship between eluting power and polarity. Eluting power is defined as the ability of the mobile phase to move a substance from stationary phase. The polarity of the solvent used in the lab can be described as Methanol> acetonitrile>acetone>ethyl acetate> hexane in decreasing order. Since Methanol and acetonitrile are more polar, they will easily separate methylene blue and methyl orange wh while other solvents will take longer time to separate. In the case of hexane, on the dyes did
the reddish pigment. This experiment aimed to answer the question, “How do cell membranes work?” The hypothesis we aim to test is: Cell membranes work as a fluid mosaic bilayer of phospholipids with many embedded proteins. We predicted that the 50% Acetone will break down the most betacyanin. Our hypothesis was proven wrong by our data collected. We could test our predictions by doing the experiment multiple times and compare the
In this study, a three step purification of alkaline phosphatase from non-pasteurized milk was reported. It included cream extraction, n-butanol treatment and acetone precipitation. Different parameters like buffer concentration, temperature, pH, substrate concentration, acetone and n-butanol treatment were optimized to maximize the enzyme activity. The enzyme was fruitfully purified upto homogeneity from the milk, with percentage recovery and fold purification of 56.17 and 17.67 respectively. The

This edge was made to ensure that there was a controlled flow of acetone up the chromatography paper.
product specifications (i.e., purity of the products) in columns were considered. The mole fraction of the acetone product in the distillate of the column C1 and the mole fraction of the produced chloroform as the distillate of the column C2 should be equal or greater than the desired product purity of 99.5mol%. Objective function For the combined optimization of the design and operation of the acetone/chloroform/DMSO extractive distillation process, the objective was the minimization of the total annual
Feet are a very important component of the human body because of the virtual function they play of ensuring mobility. Care and protection is important in ensuring healthy feet. Consider the following points in giving care to your feet. Wear appropriate shoes. Wearing the wrong type of shoes can cause deformities such as bunions, ingrown toe nails, cross over toes, hammer toes, corns and cracked heels. Avoid these by; Not wearing high heeled shoes for a long period of time as this leads to back
pigmentation during photosynthesis was performed to separate plant pigments with paper chromatography. The paper chromatography two phases are: stationary phase and the mobile phase. The paper serves as the absorbent for the stationary phase and acetone is used for the mobile phase to help pull the pigments up the page. Once the analysis of spinach pigmentation during photosynthesis was finished, the percent absorption was measured at different nanometers to see compare the difference in absorption
evaporate causing less accurate results. In addition, all the members of lab were told to expect that the first boiling point would be 81°C but the boiling point of one of the substances, acetone, was actually 56.5°C. Thus, the solution was boiled for too long and the B and C samples did not have the correct ratio of acetone to toluene. In addition, not everyone was able to get through the GC portion of the experiment due to complications in the extraction and recrystallization experiment. Thus, lab members
The two compounds that showed benzoic acid as soluble was acetone and ethanol and benzoic acid did not appear to be soluble in hexanes or water. Acetone dissolved the benzoic acid at both room temperature and increased temperature, while benzoic acid in ethanol was only slightly soluble at room temperature and completely soluble at increased temperature. Acetone is a ketone, which is a carbon chain with an oxygen attached to it [1]. Ethanol is an alcohol; it
The purpose of this experiment is to isolate myristic acid from the triglyceride, trimyristin, by using basic hydrolysis followed by acidification. First, tert-butyl methyl ether is utilized to extract the trimyristin and recrystallize from acetone to yield pure trimyristin. Sodium hydroxide, water, and ethanol are utilized to convert trimyristin to glycerol and sodium myristate. Finally, hydrogen chloride and water are applied to convert sodium myristate to myristic acid via hydrolysis. This experiment
Activation of Zero-Valent Magnesium using Acetic Acid for the Degradation of Triacetone Triperoxide in Ethanol Abstract Triacetone triperoxide (TATP), a cyclic peroxide, is an explosive frequently used by terrorists and amateur chemists due to the ease of synthesis and the availability of reagents. A degradation method for degrading TATP in ethanol (EtOH) was proposed using an activated, zero-valent magnesium (ZVMg) system. Different acids were tested to determine their effectiveness in
The objective of this experiment was to investigate the relationship of dispersion forces and hydrogen bonding forces in intermolecular attractions through the evaporation of different substances. Using temperature probes, the endothermic process of evaporation is measured by inserting the probes into the substance and then taking them out to allow the substance to evaporate, the change in temperature of the substances showed if a lot or not a lot of evaporation occurred and over how long the evaporation
