Answer:Step 1: Gather the Needed Materials (coffee Filter, Pencil, Beaker, Water Soluble Pen/marker, Water) Step 2: Cut a Strip of Filter Paper From the Coffee Filter and Using the Marker Draw a Thick Line Near the Bottom of the Filter Paper- About 1/4 Inch From the Bottom. Step 3: Allow the Water to Move Up the Paper for Approx. 5 Minutes and Then Remove the Strip From the Water Step 4: Students Should Identify the Individual Colors in the Chromatogram That Make Up the Markers Unique Mix of Ink. Step 5: Once Students Have Mastered the Technique Its Time to Put Their Skills to the Test in "The Case of the Celebrity Dog-napping" Step 7: Write the Ransom Note on a Piece of Filter Paper in One of the Suspect Inks.

Explanation: Chromatography is the physical separation of a mixture into its individual components. This lesson integrates mixtures, solutions & solubility into an activity where students will identify the solute & the solvent. Because chromatography can be used to separate the components of inks & dyes, students are able to identify the unique "recipe" that makes up the mixture of a specific brand of pen. After the students are taught the ink chromatography technique, the fun can continue with a mini forensic investigation, "The Case of the Celebrity Dog-napping".

The chromatography for the color in an ink has been the vertical adsorption paper chromatography.

Chromatography has been an analytical technique used for the determination of the constituents in the sample. The sample has been determined both qualitatively and quantitatively.

Chromatography experiment for Color of Ink

The chromatography has been used for the qualitative determination of the constituents of ink has been vertical paper chromatography.

The ink spot has been placed on to the stationary phase of the medium. The paper or stationary phase has been dipped slightly from the tips in the mobile phase.

The movement of the mobile phase with the ink has been results in the distribution of the ink colors. Thus, the determination has been performed.

Thus, the chromatography for the color in an ink has been the vertical adsorption paper chromatography.
