Can the elements that make up a compound be separated using techniques such as chromatography or evaporation?
No, chromatography separates compounds based on their different affinities to a stationary phase, while evaporation separates based on differences in volatility. Both techniques are used to separate mixtures of compounds, not individual elements within a compound. Elements within a compound are chemically bonded and cannot be separated using physical techniques like these.
Is chromatography physical change?
Chromatography is a physical change because even though you are separating colors the original atomic identity of the colored ink being separated is still retained showing that a chemical reaction has not taken place.
What type of chromatography would be used to separate two proteins?
Size exclusion chromatography would be ideal for separating two proteins based on their size. This technique separates proteins by allowing smaller proteins to enter the pores of the stationary phase while larger proteins elute first.
How does any particle separate?
Given the enormous number of different kinds of particles, and the various types of attachments that those particles can have to other particles, your question is very broad. But broadly speaking, particles separate because of some kind of force that is acting upon them.
Iupac definition of chromatography?
"Chromatography is a physical method of separation in which the components to be separated are distributed between two phases, one of which is stationary while the other moves in a definite direction."
What is the significance of tlc plate polarity in chromatography separation techniques?
The polarity of a TLC plate is important in chromatography because it affects how different compounds move and separate on the plate. Compounds with similar polarities will move together, while those with different polarities will separate. This helps in identifying and analyzing different compounds in a mixture.
Ways to separate mixture?
Some common methods to separate a mixture include filtration, distillation, chromatography, and evaporation. Filtration is used to separate solids from liquids, while distillation can separate liquids based on their boiling points. Chromatography is effective for separating different components in a mixture based on their interactions with a stationary phase, and evaporation can be used to separate a solvent from a solute.
How do you separate amino acids from fatty acids?
One common method to separate amino acids from fatty acids is through chromatography. Amino acids are more polar and can be separated based on their different affinities for the stationary phase, while fatty acids can be eluted separately due to their differing solubilities. Another method could involve precipitation using different solvents where amino acids and fatty acids can be separated based on their solubilities in the respective solvents.
How do you separate nucleotides from glucose?
A nucleotide components are a nitrogenous base, a five-carbon sugar and a phosphate while Glucose is a six-carbon sugar therefore a nucleotide is much larger than in size than a glucose molecule. The size difference could be used to separate the molecules. Or considering the differences of charge/ solubility of the nitrogeneous base as well as the phosphate groups to separate from glucose.

Differences between extraction and chromatography?
both the terms can be alternatively used but chromatography is seperation of mixture i.e. all the components in the mixture are seperated but in the extraction only the desired one is seperated
What is the significance of TLC polarity in determining the separation efficiency of compounds in chromatography?
The polarity of TLC (thin-layer chromatography) is important because it helps determine how well compounds will separate during the chromatography process. Compounds with similar polarities will move together, while compounds with different polarities will separate more efficiently. This is because the stationary phase in TLC interacts differently with compounds based on their polarity, allowing for better separation.
Why do some dyes separate into different colours while some do not?
Some dyes separate into different colors on a surface or in a liquid due to differences in their molecular structure that cause them to interact differently with light. This often happens in chromatography techniques where different dye molecules move at different rates. Dyes that do not separate typically have similar molecular structures that interact similarly with light, resulting in a single color.
What are the key differences between cation exchange chromatography and anion exchange chromatography?
Cation exchange chromatography separates molecules based on their positive charge, while anion exchange chromatography separates molecules based on their negative charge. The key difference lies in the type of charge that is used to separate the molecules.
