What is the purpose of double spotting the chromatography paper?
The chromatography paper is spotted twice so as to increase the amount of sample used for the separation on the paper. This is to allow distinct banding of the sample into its constituents.
What factors affect separation of pigments?
...are: -the attraction to the paper -the solubility of the pigments -the size of the particles posted by Huguito Doutre
How is chromatography used to study plant pigment?
chromatography is basically a technique used for the separation of different components.... plant pigment consist of different components..... the sample is taken nd spotted over a chromatography paper..... nd den it is kept in suitable solvent to get separated...... different components travel different distance on chromatogram.... dis is how v cn use chromatography to study plant pigments...
What is paper chromatographic separation in chemistry?
Paper chromatography is an analytical chemistry technique for separating and identifying mixtures that are or can be colored, especially pigments. This can also be used in secondary or primary colors in ink experiments. This method has been largely replaced by thin layer chromatography, however it is still a powerful teaching tool. Two-way paper chromatography, also called two-dimensional chromatography, involves using two solvents and rotating the paper 90° in between. This is useful for separating complex mixtures of similar compounds, for example, amino acids.
Which gives better results ascending or descending paper chromatography?
Paper chromatography is an analytical method of separating mixtures into their constituents. In the ascending technique, the separation of the mixture is against gravity.
What procedure did you to separate plant pigments?
Paper chromatography can be used to separate pigments in plants. The pigments are separated into chlorophylls (greenish colors) and carotenoids (yellowish colors).

What is the purpose of the solvent in chromatography?
The basic purpose of the solvent is to move the pigments up the chromatography paper through capillary action so that the pigments can be separated. The basic importance of chromatography is to separate different solvents by their molar mass. In doing so, one can separate the different pigments within a solution and measure how much of each pigment is present.
Why does carotene travel farthest in chromatography of leaf pigments?
it has more affinity (attraction) to the solvent than to the paper
Uses for paper chromatography?
They are used in many scientific studies to identify unknown organic and inorganic compounds. They are also used in crime scene investigation, DNA and RNA sequencing, among others. Essentially, any solution can be separated through some form of chromatography.
What procedure did you use to separate plant pigments?
Place leaf in beaker and heat with Bunsen burner until water has discolored and boiled, then place leaf in test tube filled methylated spirits and place in same beaker as before with the burner turned OFF. Methylated spirits boils at around 80 degrees Celsius so when placed in heated water it will boil. This process will separate the chlorophyll (pigment) in the leaf.
What disadvantages are there in needing a reference set of chemicals?
because the chromatography paper is only short length
How do you separate ink in colour?
you put ink on the bottom of the chromatography paper and dip one end of of it into water and leave it to stoke up the paper, separating the ink pigments
