What is function of butanol in paper chromatography?
Butanol is used as a solvent in paper chromatography because it can dissolve a wide range of compounds. It helps to carry the sample and allow it to migrate up the paper. Butanol also helps in separating the components of the sample by interacting differently with different compounds.
What would happen if the Spot of origin is lowered into the solvent in chromatography?
If the original spots were below the level of developing solvent then the components of the spotted sample would dissolve into the solvent and no spots would be seen upon analysis because all of the sample is dissolved in the developing solvent. hope this helps. good luck in o. chem!
How does concentration effect retention in paper chromatography?
In paper chromatography, increasing the concentration of the solvent can improve retention of the analytes by slowing down their movement along the paper. Higher solvent concentrations allow for more interactions between the analyte and the stationary phase (paper), leading to better separation and retention of the components in the sample. However, excessively high solvent concentrations may cause the analytes to move too slowly or not at all, impacting the overall efficiency of the chromatographic separation.
What is the purpose of double spotting the chromatography paper?
Double-spotting chromatography paper helps ensure that the substance being analyzed is evenly distributed across the paper to enhance separation and analysis. It can also be used as a reference spot to track the movement of the solvent front during the chromatography process.
What is the significance of Rf value in chromatography?
The Rf value, or retention factor, in chromatography is a measure of how far a compound travels in relation to the solvent front in a chromatogram. It helps in identifying and characterizing compounds based on their movement and separation in the chromatographic system. Comparing Rf values can aid in qualitative analysis, determination of purity, and identification of unknown components within a sample.

What are the advantages of using TLC solvent systems in chromatography techniques?
Using TLC solvent systems in chromatography techniques offers several advantages. These include the ability to separate and identify different compounds in a mixture, the flexibility to use a variety of solvent systems for different types of compounds, and the quick and cost-effective nature of the technique. Additionally, TLC solvent systems allow for easy visualization of separated compounds, making it a popular choice in analytical chemistry.

Why is it important that the level of the elution solvent not drop below the top of the absorbent?
If the level of the elution solvent drops below the top of the absorbent, it can cause the sample to dry out prematurely, leading to incomplete elution and loss of analyte. This can result in inaccurate or inconsistent results in chromatography. Maintaining the solvent level above the absorbent ensures proper elution and retention of the analyte through the stationary phase.
How do you change the percentage of solution?
You can eitheradd more solvent,allow some solvent to evaporate,add more solute,allow the solute to precipitate and remove some.
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 will chromatography do to the pigments in the plant extract?
Chromatography will separate the pigments in the plant extract based on their different affinities for the stationary and mobile phases. This separation will allow for the identification and quantification of individual pigments within the extract.
Is it true that adaptations allow an animal to migrate to a different biome to survive?
Yes.
