Paper Chromatography
What is the purpose of paper chromatography?
To separate mixtures.
What do I attach the top of my filter paper to?
The Splint
What does soluble mean?
Dissolvable
What is the mobile phase?
The solvent
Where do i fill the beaker using solvent (e.g, water) up to?
Slightly below the pencil line, and just touching the ink dot.
What is a mixture? (Is it chemically combined?)
A mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs between the components.
What is the stationary phase?
The filter paper
Ideally, how many centimetre (cm) should I draw my pencil line (bottom) on the filter paper?
Around 1cm
What happens as the filter paper is partially placed inside the beaker containing solvent (Water).
Water is dissolved, moving up the filter paper chromatogram.
Why do you draw the starting line in pencil?
You should always draw it in pencil because it is insoluble.
Ideally, how many centimetre (cm) should I draw my solvent front on the filter paper and would I use a pencil or a pen?
3cm and a pencil
What happens to the ink mixture as water passes up the filter paper?
The ink mixture will separate into individual soluble components.
