How does column chromatography separate a mixture of methylene blue and methyl orange?
Methylene blue and methyl orange will have different binding affinities with the column material, and thus one will pass through the column more slowly than the other. This will result in one of the compounds being eluted from he column before the other. The one with the weakest binding to the column will be eluted first.

How do you separate a compound from a mixture?
One common method to separate a compound from a mixture is through chromatography. This technique uses the different affinities of components in the mixture for a stationary phase to separate them. By passing the mixture through a column or paper containing the stationary phase, the compound can be isolated based on its unique properties. Additionally, techniques such as filtration, distillation, and extraction can also be employed depending on the nature of the compound and the mixture.
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
How is silica gel column chromatography used in the separation and purification of compounds?
Silica gel column chromatography is a technique used to separate and purify compounds based on their different affinities for the silica gel. The mixture of compounds is loaded onto a column filled with silica gel, and as the solvent flows through the column, the compounds move at different rates based on their interactions with the silica gel. This results in the compounds separating into distinct bands, allowing for their isolation and purification.
Why does fluorenone travel in methylene chloride?
Presumably you are talking about in a chromatography column with alumina in it. The fluorenone is polar and subsequently creates a bond with the polar alumina. However, as Chlorine is more electronegative then the oxygens on alumina, the fluorenone wants to hang out and be friends with the methylene chloride even more than alumina, so the fluorenone and the methylene chloride hold hands and take a romantic walk down the column into your solution.
What process that uses pressure to separate substances in a solution?
The process you are referring to is likely a type of chromatography, known as high pressure liquid chromatography (HPLC). In HPLC, a liquid mobile phase is passed through a column of stationary phase under high pressure, separating the components of a mixture based on their interaction with the stationary phase.
How can seprate p-nitro acetanilide mixture of para and ortho acetanilide?
The amide group on acetanilide is an ortho/para director, so a simple nitration should work: a mixture of sulfiric acid and nitric acid should be sufficient. Afterward, separation of the ortho and para compounds (by column chromatography, probably) would be necessary.
What are some ways chromatography can separate chemicals in a mixture?
Chromatography separates chemicals based on their affinity for a stationary phase and a mobile phase, allowing them to travel at different rates. Different types of chromatography like gas chromatography, liquid chromatography, and thin-layer chromatography utilize different mechanisms such as adsorption, partition, ion exchange, and size exclusion to separate the components in a mixture. By adjusting the conditions like solvent polarity, temperature, and column material, chromatography can effectively separate complex mixtures into individual components.
What is the name of the method used to separate dyes?
Chromatography is the method used to separate dyes by allowing the components to move at different rates through a medium, such as paper or a column, based on their affinity for the medium and solvent. This technique separates the different dyes based on their molecular interactions with the moving phase.
What is column efficiency?
Column efficiency refers to the ability of a column in chromatography to separate compounds effectively. A more efficient column will result in better separation of components in a mixture and sharper peaks in the chromatogram. Efficiency is influenced by factors such as column length, particle size, and packing material.
Which chromatography to separate non volatile compounds?
Column chromatography is commonly used to separate non-volatile compounds based on their interactions with the stationary phase within the column. The compounds are separated as they travel at different rates through the column due to varying affinities to the stationary phase.
How many different components are in column chromatography?
Column chromatography can separate a mixture into multiple components, typically ranging from two to several hundred, depending on the complexity of the mixture and the specific conditions used. The number of components that can be resolved is influenced by factors such as the nature of the stationary and mobile phases, the size of the column, and the characteristics of the compounds being separated. In practice, effective separation often requires optimization of these parameters to achieve the desired resolution.

How do you separate the enzymes in column chromatography?
In column chromatography, the enzymes are made to pass through the column without occurrence of bubbles. These enzymes are obtained at the end of the process by slowly advancing through every column.
What are the main applications of column chromatography?
Column chromatography is used in the lab and industry to isolate the compound that they want. Since some chemical reactions are not selective to the product you want, you have to get rid of the products you don't want. Sometimes column chromatography is the only way.
Why do the pigments separate during column chromatography?
Because the retention coefficients of different substances are also different.
How does a gas liquid chromatography work?
Gas liquid chromatography separates components of a mixture based on differences in their interaction with a stationary phase and a mobile gas phase. The sample is vaporized and carried through a column by an inert gas, where it interacts with the stationary phase. Components with stronger interactions take longer to travel through the column, causing them to separate and be detected at different times.
