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.
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.
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 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.
What is the interpretation of paper chromatography?
whate is interpretation in paper chromatography
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
A method of separating coloured mixtures?
Paper chromatography is a method.

Three methods of separating mixtures?
Filtration Paper Chromatography Distillation
A method of separating mixtures by using chromatographic paper and a solvent?
This method is called paper chromatography.
What is the name of the process of separating?
ir in the case of inks and its likes. Paper Chromatography.
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 paper chromotogrophy?
Paper chromatography is an analytical method technique for separating and identifying mixtures that are or can be colored, especially pigments. This can also be used in secondary or primary colours in ink experiments. This method has been largely replaced by thin layer chromatography, but is still a powerful teaching tool. Double-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 compounds having similar polarity, for example, amino acids. If a filter paper is used, it should be of a high quality paper. The mobile phase is developing solutions that can travel up to the stationary phase carrying the sample alongside with it.

Why does carotene travel farthest in chromatography of leaf pigments?
it has more affinity (attraction) to the solvent than to the paper
