How Chromatography can be used for non colored solution?
Many organic compounds are aromatic and thus absorb ultraviolet light. Simply shine UV over your TLC plate and observe the spots. If the compound isn't UV absorbing but has a double bond, a solution of KMnO4 can be used to visibly stain the compound on the TLC plate.
What is the root meaning of chromatography?
Chromatography comes from the Greek chrom- meaning "colored" and graph- meaning "writing" so it literally means "colored writing".
What is role of ninhydrin in thin layer chromatography?
Ninhydrin is used as a visualization reagent in thin layer chromatography to detect amino acids and other compounds that contain primary amines. When sprayed onto the developed TLC plate and heated, ninhydrin reacts with primary amines to form colored products, allowing for visualization and identification of the separated compounds.
How does coloured rings form when chromatography is made?
Colored rings form during chromatography due to the separation of different components in a mixture based on their affinity for the stationary and mobile phases. As the components move through the chromatography medium at different rates, they separate into distinct bands or rings, each representing a different compound in the mixture. The coloration may result from the absorption of specific wavelengths of light by the separated compounds.
What is the general purpose of candy chromatography?
The general purpose of candy chromatography is to separate and analyze the different components present in a mixture of colored dyes used in candies. By using a chromatography technique, it is possible to identify and quantify the substances that contribute to the color of the candies.

How do you separate the coloured dyes in an ink?
Colored dyes in an ink can be separated using techniques such as chromatography, where the dyes are dissolved and then separated based on their different affinities for the mobile and stationary phases. Another method is distillation, which involves heating the ink to separate the dyes based on their boiling points.

What is the purpose of using ninhydrin as a TLC stain in chromatography experiments?
Ninhydrin is used as a TLC stain in chromatography experiments to detect and visualize amino acids and other compounds that contain primary amines. It reacts with these compounds to form a colored product, making it easier to identify and analyze them on the chromatogram.

Why do you need a locating agent in an experiment to separate amino acids by chromatography?
A locating agent is essential in chromatography for separating amino acids because it helps visualize the separated compounds after the chromatography process. Since amino acids are often colorless and difficult to detect, a locating agent can react with them to produce colored spots, making it easier to identify and measure their positions on the chromatogram. This visualization is crucial for analyzing the results and determining the presence and quantity of specific amino acids.
Why it is necessary to spray a chromatogram with a locating agent?
Spraying a chromatogram with a locating agent helps visualize the separated compounds on the chromatogram. It aids in locating and identifying the compounds of interest present in the sample by producing color changes or fluorescence, making it easier to analyze and interpret the results of the separation.
Which method of separation is commonly used for separating mixtures of colored substances?
Chromatography
Why you will spray ninhydrin for analysis in chromatography?
Since amino acids are colourless compounds, ninhydrin is used for detecting them. To identify this, after development, the TLC plate is sprayed with ninhydrin reagent and dried in an oven, at 105°C for about 5 minutes. Ninhydrin reacts with α- amino acids that results in purple coloured spots [(due to the formation of the complex - Rheuman's purple).
