Marker is NOT a homegeneous mixture. It is heteregeneous. The ink can be separated by chromatography.
ethanol, colorant
its a substace because it not pure... how do i know.. well i just do Some are pure substances : chalk, charcoal, graphite and pure lead are examples. Some are solutions, some are suspensions, many are a mixture.
If you get permanent marker or ink on a hard surface and you need to get it off, spray the ink with hairspray, let the hairspray set for thirty seconds and then wipe it off. Most of the ink will come off with it, and you can clean the rest off with soap and water. Or using nail polish remover. Just dab the remover all over the ink, then blot off the ink and remover with a rag - don't rub, you'll end up smearing the marker and making a bigger mess. If the smell bothers you, spray the couch with Febreeze.
Markers contain ink in the inside. Like pens they contain ink.
no you cant because the marker ink will wear off onto the surface of a desk or so on.

yes, yes you can !
The ink of a marker used to be made of toluene and xylene. These substances were found to be quite harmful so now the ink is usually made out of alcohols such as 1-propanol, 1-butanol, diacetone alcohol and cresois.
What ?
The evidence that exists that marker ink is a mixture is that the ink can be separated into black and other color pigments. This can be done on filter paper by dotting the marker just above the edge and adding ethyl alcohol, which drags the pigments separately across the paper.
