Paper Chromatography Flashcards
what’s separated in paper chromatography
mixtures of soluble substances
what does it mean when a component travels the furthest
it means that the component is highly soluble in the solvent
they are also minimally attracted to the chromatography paper
what type of phase is a solvent
its a mobile phase
what type of phase is the chromatography paper
Stationary phase
what does chromatography produce
Chromatography produces chromatograms
whats the equation for Rf value
Rf = Distance travelled by substance / distanced travelled by solvent
what are the 3 things that describe a reference substance
1) Used in chromatography
2) Can provide indication of substance present
3) Pure sample
What can we say if the Rf values of a reference and a spot match in all solvents?
its very likely that the mixture contains the reference compound
whats the apparatus required for paper chromatography
1) Chromatography paper
2) Beaker
3) Solvent
