Question

Which yielded the better chromatogram-the ink from the pentel pen, the sign pen or the ballpen?

Answer 1

The ink from the sign pen.

Step-by-step explanation:

Hello,

At first, remember that chromatogram is defined as a visible record (such as a graph) showing the result of separating the components of a mixture by chromatography.

Now, in this case, one can obtain the best chromatogram by using sign pen since it is the most rapid when moving through the paper.

Best regards.

Answer 2

I think the correct answer from the choices above is the first option. I would say the ink from pentel pen would yield a better chromatogram. This is because it will have the least viscosity among the three choices. Hope this answers the question. Have a nice day.
