Why is it important to keep the spots applied to TLC slides for chromatography as small as possible?
Keeping the spots small helps to prevent overlapping and spreading, which can affect the accuracy of the chromatography results. Small spots also minimize the potential for contamination and ensure a more controlled separation process. Additionally, small spots help in reducing the time required for the analysis.
How does ninhydrin solution help in the visualisation of developed spots?
Ninhydrin solution reacts with amino acids in the developed spots, producing a purple color. This color change makes the spots more visible and helps in their visualization on chromatography materials.
What are some possible alternatives for paper chromatography?
Some possible alternatives for paper chromatography include thin-layer chromatography (TLC), gas chromatography, high-performance liquid chromatography (HPLC), and capillary electrophoresis. These techniques offer different separation mechanisms and have varying applications depending on the analyte and desired outcome.
Paper chromatography Why must the spot be concentrated?
Keeping a small spot on TLC will allow for greater resolution between the spots allowing for more accurate Rf calculations and solvent separation/preparation if used to isolate a compound in a mixture.
What are the different types of chromatography?
The main types of chromatography include gas chromatography (GC), liquid chromatography (LC), thin-layer chromatography (TLC), and high-performance liquid chromatography (HPLC). Each type of chromatography separates compounds based on their differing affinities for a mobile phase and a stationary phase.
Why must the level ofthe solvent not reach the pencil line where the spots are?
If the solvent level reaches the pencil line where the spots are, it can dissolve the compounds in the mixture, causing them to spread out and overlap. This can lead to inaccurate results and difficulties in analyzing the separated components on the chromatogram. It's important to maintain the separation of the compounds on the chromatography plate for clear identification.

What would be the result if the spots were made to large in a thin layer chromatography experiment?
it would be difficult to read as they would merge

Why do some region overlap?
they dont
What are some synonyms of the term 'overlap'?
Some synonyms of the term overlap are extend along and fold over. The word overlap is defined as to lie over something else or the winged or extended part of an object.

What are 3 types of chromatography?
1. thin -layer chromatography 2. gas chromatography 3. liquid chromatography
Why should the amino acids spots not be submerged within the solvent?
I assume you are talking about thin-layer chromatography. If the spots are submerged in the solvent, they will dissolve into it and become so diluted that they will most likely be undetectable. Plus, they will elute as a band, not as a spot. Your solvent will also be contaminated.
What is The appearance of chromatograms in paper chromatography?
Chromatograms in paper chromatography appear as a series of colored spots on the paper strip or plate. The spots are formed by the separation of components in the sample, with each spot representing a different compound. The distance traveled by each spot can be used to identify and quantify the components in the sample.
