My hypothesis was incorrect. I hypothesized that acetone would be the most effective in separating the pigments in the black marker. What I discovered is different solvents draw out different pigments in the black marker. Solvents are more effective in drawing out the pigments with similar properties. The ink in the marker was meant to dissolve in water (water-soluble). So, distilled water was, in fact, the most effective in drawing out the major pigments (purple and blue) from the black marker. White vinegar was effective in drawing out the major pigments but not as effective as the distilled water. Acetone, also known as dimethyl ketone, occurs naturally in the environment and dissolves in water yet it was the least effective in drawing out the major pigments (purple and blue) but was effective in drawing out the yellow pigment. Blue and purple are on the strip dipped in acetone but not nearly as much as yellow. The yellow pigment was drawn to the acetone because the properties in the yellow pigment were more similar to the properties in acetone. The yellow pigment was not attracted to the properties in distilled water or white vinegar. So, I learned that one solvent doesn’t necessarily bring out more or all of the pigments in a black marker as I thought. But, each solvent can bring out the different pigments that are most like the properties in the solvents.
