you used a pencil to mark the chromatography paper since the carbon in the "lead" pencil does not dissolve in the solute. why does carbon not dissolve? what type of pen (ink) will also not produce a chromatogram when water is used as the solovent? explain using principles based of the polarity of particles

  • chem -

    Carbon doesn't dissolve in water because C is not polar. India ink is essentially C (I think lamp black) and will not dissolve in water.
