Is a paper chromatography IA too simple for HL Chemistry?

Recommended Posts

Hi there, 

I am thinking about doing my chemistry IA on paper chromatography of black and red henna dye. However, would this be too simple for Higher Level?

So you don't ever want to do a lab for IA just to illustrate a technique. Paper chromatography should be part of a large lab.

I asked my teacher and she mentioned that the practical component doesn’t have to be complex, it just has to be explored well. Thoughts??
