Design Lab
Does black ink from different permanent markers contain the same dye? Plan and design a lab showing answer.?
They are different.
You can show this with paper chromotography.
You can use several types of solvents
Use filter paper as the paper.cut in strips, water, alcohol
start with a small dot of ink on each piece, near the tip
put only the tip of the paper in the liquid
the dot will separate into colrs and they will travel up the strip.
You put it into lab form.
