Paper chromatography can be used in separating amino acids and anions, RNA fingerprinting, and testing histamines and antibiotics. (Infromation received from sonic.org Purpose The purpose of this experiment was to separate the dyes that these markers are composed of and show how chromatography works. Materials * Four different markers (including one black permanent marker) * Rubbing alcohol or isopropyl alcohol * Coffee filters (2) * Tall glasses or plastic cups (2) * Pencil * Ruler * Tape * Table salt * Water * Measuring cups/spoons * Clean pitcher or 2-liter bottle Procedure 1. Your first task is to cut the coffee filter into a rectangle measuring three cm by nine cm. You will need 2 for this lab.
Temperature: Make sure the plants have the same temperature in its surroundings. Part 2 Purpose Getting rid of unwanted weeds in the yard. Research Whether or not home remedies or commercial herbicides are more effective and reliable. Reliable internet sources ending in .gov, .edu, .org, and or .fsu . and Weed control experts.
3. Measure 1/4 c sugar; add to milk/cream mixture in baggie. 4. Close the bag SECURELY, squeezing most of the air out before sealing. 5.
Then measure the distance of each pigment starting at the bottom of the pigment origin to the bottom of the separated pigment band. In Exercise 4B: Photosynthesis/ The Light Reaction, chloroplasts are extracted from spinach leaves and incubated with DPIP in the presence of light. The spectrophotometer should be warmed up and set the wavelength to 605 nm. An incubation area should be set up, that includes a light, water flask, and test tube rack. We were provided with two beakers, one containing a solution of boiled chloroplasts and
Materials: * Heavy duty zip-lock baggie * 1 strawberry (fresh or frozen and thawed) * Cheesecloth * Funnel * 100 ml beaker * Test Tube * Wooden coffee stirrer * DNA extraction buffer * Ice-cold 95% isopropyl alcohol Hypothesis: DNA can be extracted if you use certain buffers. Procedure: 1. Place one strawberry in a zip lock baggie and carefully press out all of the air and seal the bag.
Tap the magnet gently on the side of the beaker to dislodge the wood shavings. 15. Complete the Magnetic column in the data sheet. 16. Put a few iron filings back into the 100 mL beaker.
Ink Chromatography Background Information and Research Paper chromatography helps separate a solution with multiple components. Paper chromatography helps chemists and biologists identify organic and inorganic compounds. It is also used in DNA and RNA sequencing. Biologists sometimes use paper chromatography to separate plant pigments. Purpose The purpose of this experiment is to see the effect that paper chromatography has on ink.
Experiment & Observation I gathered together my items; distilled water, salt, ruler, scissors, stapler pencil, tape, 16 toothpicks, Kool-Aid drink mix strawberry and grape, set of McCormick food coloring red, yellow, green and blue, small bag of M&M candy, plastic beaker 50 mL, petri dish 60mm, well-plate 24, FDC blue dye #1 0.5 mL vial, FDC blue dye #2 0.5 mL vial FDC red dye #3 0.5 mL vial, FDC red dye #40 0.5 mL vial, FDC yellow dye #5 0.5 mL vial, FDC yellow dye #6 0.5 mL vial, unknown 0.5 mL vial, 3 filter paper chrom 14x7 cm. I first made a solvent using a 50 mL beaker with warm room temperature distilled water and a pinch of salt. I made sure the salt was completely dissolved and set the solvent aside. I took out two of the Chromatography filter paper sheets 14x7 and with a pencil very lightly drew a horizontal line 1 cm from the bottom of both sheet. Then horizontally on the line I just drew I marked off 9 spaces 1.5 cm apart.
