5.05 Ink Chromatography Basic Lab Components Background Information and Research: 1. Paper chromatography type of method that is used to separate mixtures of substances from a solution. 2. There are many uses for paper chromatography‚ especially concerning the fields of chemistry and biology. One use is to allow scientists to detect any sort of contaminants is rainwater. Another use is to identify clues at a crime scene such as blood‚ ink‚ or drugs. However‚ the more common use is to

The best dye to use is Manic Panic. Their website is manicpanic.com. They even have little bleaching kits‚ perfect for dip-dying your tips. I used to bleach and dye my hair a different color every month when I was in high school. (my hair is hot pink and black in my senior picture) I have tried almost every semi-permanent metallic dye and that’s definitely what you see pictured above. The colors look like After Midnight Blue (dark blue)‚ Bad Boy Blue (light blue)‚ Hot Hot Pink (dark pink)‚ and Cotton

Introduction Flash-Column Chromatography is another useful technique used to separate and purify complex mixtures of compounds. In this experiment‚ TLC is used to determine the best solvent system for the column. Due to Flash-Column Chromatography1 being an inexpensive technique‚ many scientist use this process for drug and natural product purification. Method By using the information from Experiment 6B‚ the TLC solvent system used was 30% EtOAc: 70% Hex. Experiment 7 was broken into two parts‚

Energy in food lab report Aim: How much energy there is in food. Hypothesis: If I work out how much the water temperature has risen by burning food underneath water‚ the mass of the water and the mass of food I can work out how much energy was in the food. Introduction: This experiment is about how much energy there is in food. There are a few different types of energy‚ the one we are looking at is chemical energy. Some other types of energy are: thermal energy which is heat‚ magnetic energy which

Ink Chromatography Lab Background Information Paper chromatography is an analytical method that is used for separating and identifying mixtures of substances into their smaller parts. Paper chromatography works because the ink used contains several dyes (pigments) that when place on porous paper are dissolved in a solvent by capillary action. When the pigments (solutes) are dissolved in the solvent (water & alcohol mixture) they move through the paper at different rates depending on their

separated by a procedure called chromatography. The procedure uses a special paper and solvent. The chlorophyll molecules adhere to the paper. The solvent molecules move up the paper by capillary action. Each chlorophyll molecule will travel up the paper at different rates. Hypothesis: If chlorophyll is removed from the plant‚ then the different pigments in the plant can be visible. Materials: -Spinach -Coin -Chromatography paper -Ruler

5.05 Mixtures and solutions Lab report Ink Chromatography Chromatography is also used to compare and describe chemical substances. The chromatographic sequence of sorbed substances is related to their atomic and molecular structures. A change in a chemical substance produced by a chemical or biological reaction often alters the solubility and migration rate. With this knowledge‚ alterations or changes can be detected in the substance. Chromatography serves mainly as a tool for the examination and
