Experimental process:1. Take a piece of chromatography paper (or filter paper/ paper towel). Draw a pencil line across itabout 1 cm from one end. Using colored markers (pentel pen), place small spots of color on thecenter of the line.2. Put water in the glass container to a depth of about 0.5 cm.3. Tape the chromatography paper in a pencil and hang it in the glass container so that it dips into thewater but with spots of color above the water level.Pencil-Paper clip-Strip of filterраper-Jar-Srip of filterраper-Spot of ink-Line drawnby pencil-WaterSpot of ink(a)(b)https://www.topperieaming.com/answer/how-will-you-separate-dyes-in-black-ink-using-chromatography-explain-t-with-the-help-of-a-diagram/spxgq715522. Allow the water to rise up the paper until it is almost to the top.3. Remove the paper, mark where the water reached (solvent front), and hang it up to dry.4. When dry, measure the distances moved by the spots and the solvent front. 1. Why should the line of the bottom of the paper be drawn on a pencil?2. What would happen if the level of the solvent came above the level of the spots at the start?

In order to execute paper chromatography, which of the following stages is required?I. Load the standard/s beside the sample spotsII. Allow the chromatogram to touch sides of beakerIII. Saturate the chamber with vapor of the mobile phaseIV. Place the spots at the same height as the solvent level
Task: You are a forensic analyst employed at the Baltimore County Forensic Lab. You plan to perform paper chromatography on the ink from the note and a sample from the marker. Permanent marker ink is non-polar. You need to select the best solvent to use as the mobile phase in order to compare the ink sample and determine if they may be a match. The solvents you have available to you are carbon tetrachloride and water.Which solvent would be best to analyze the ink samples using paper chromotography?Your explanation should include:• the name of the liquid solvent that should be used for the paper chromatography analysis• scientific reasoning for your choice of the liquid solvent that will be used• the Lewis structures for carbon tetrachloride, CCl4, and water, H2O• how the shape and symmetry of each molecule influences its polarity
