Different dyes in ink travel through the chromatography filter paper at different speeds.

. Black is an exciting color. Cut it in such a way that the grain of the filter paper runs parallel to the 10 cm dimension of the strip. Capillary action makes the marker dye move up the paper towel.

Bend the top of the paper towel over the rim of the glass and secure it with a rubber band. Theres a force between the water molecules and the molecules in the paper towel. Use a pencil and make a mark on the paper strip beside the ink dot.

Middle School Science. Of a grain of rice about 15 cm up from the pointed end of the paper. Assign a number to each pen.

Place your paper on top of an empty plastic cup. Lab Ch 3 Chromatography of Markers MMs Part 1. 3 Black Ink Pens Markers 6.

Draw a large dot of color black works best about an inch from the bottom of the strip of paper. Place the bottom of the paper below the dot into the water. Distilled water rubbing alcohol 3.

Cut the coffee filter into long strips about 3 4 cm wide and 10 cm long. Must be polar Ex. Choose two marker colors and draw a simple design.

Chromatography paper in the dots will be above the liquid level. How about the ink in black markers. Read PDF Paper Chromatography Experiment Paper Chromatography Experiment.

Using a sharp pencil NOT PEN poke a small hole in the center of the filter paper. Cut strips of paper towel approximately 120 cm by 30 cm then cut the bottom of each strip on an angle so that the bottom is a point. On a coffee filter or paper towel draw a circle with the black marker of your choice.

Half fill the cup with water. Tape the paper towel strip from the end opposite to the pen line onto the middle of the straw so the strip will hang when the straw is placed crosswise onto the cup. The water moves upward through the paper towel lifting the washable dye molecules with it.

Marker inks are made from many different colored dyes. Use a magic marker to draw a line across the bottom of the strip above the point. If you ever got a paper with ink wet you would have seen the ink move across the page in streaks.

Using the pipette drop water by droplets onto your paper in the center of the circle you drew with black marker. Cut the paper towel. Put a piece of paper or paper towel under the filter before coloring.

Draw a line across 6 paper towel strips or coffee filter strips about 1 inch from the bottom. When the end of the paper towel strip is submerged in water the water soaks up through the paper towel. Chromatography Paper White Paper Towels can be used as a substitute 2.

What appears to be happening. With paper chromatography you can separate the color of a marker into its individual color molecules. This is called chromatography - separating the parts of a mixture so that you can see them one.

Using the same set up repeat the experiment with different types of black ink pen markerPaper Chromatography Chromatography is an analytical tool for distinguishing different biomolecule based on their chemical properties. Choose one primary color red yellow blue and one secondary color purple green orange. Some pigments dissolve in water easier and are pulled with the water farther up the paper.

Pigments Using 1 marker per 12 coffee filter color a bold line 12in from the bottom filter edge. Fill the bottom of a bowl or glass with a little water. In this family science activity families can experiment with a home version of paper chromatography using ordinary coffee filters water and water-soluble markers.

Heres the really cool science behind chromatographyWhen the paper towel is dipped in water some of the water sticks to the paper towel and gets it wet. 12 When the isopropyl alcohol is about 1cm from the top of the paper remove the paper and lay it flat on a. Assign the marker a letter or code so you remember which marker is which.

The water also sticks to itself. When the water passes through the black ink it takes the pigment colors with it. Then cut paper towels or coffee filters into long strips.

Hang the strip with the tip just in the water. This is most obvious with dark colors such as black and purple Each dye is made up of different chemicals some heavier and some lighter that travel at different speeds as the water moves them up the paper. Paper Chromatography of Gel Ink Pens.

What you do. 2 cm by 15 cm. With a black water soluble marker place a small but concentrated spot of ink from marker about 1cm from the center hole onto the filter paper.

The most soluble colours dissolve and travel further and faster than less soluble dyes which stick to the paper more. Place your drawing on a tray or towel. Chromatography is a way of separating out a mixture of chemicals.

Do the same for all the pens and be sure to label the strips. Then take out the chromatography paper. Take your colored filter and place the bottom edge inside.

Slowly add drops of water until the water starts to bleed through the black circle. Cut a coffee filter or paper towel into sections. Fold each strip along the 10 cm dimension so as to.

Obtain a small piece of tape and gently curl the paper into a cylinder with the spots on the outside. Then draw a squiggly line across a strip of paper towel with one of your black pens about an inch up from the bottom. When the filter paper containing the ink spots is placed in the solvent in this case water the dyes travel through the paper.

11 Add the chromatography paper to the 100ml beaker and watch the movement of the solvent. First cut a paper towel into strips about one inch wide. Once the water starts moving the paper will stick to the side.

Do this for both markers. Lower the pointed end of the paper into the solvent BUT make sure the color dot stays above the solvent level. Procedures for Markers 1.

One of the oldest and most reliable forms of chromatograpy is paper. Obtain a piece of filter paper. Make sure the markers are washable.

Go back over each ink spot a second time to ensure there is enough ink in the spot.
