What is used as the stationary phase in paper chromatography?
The stationary phase in paper chromatography is the paper itself.
What is the role of the stationary phase in paper chromatography?
The stationary phase in paper chromatography acts as a medium for separating different components of a mixture based on their affinity for the stationary phase. It helps to slow down the movement of the components as they travel through the paper, allowing for the separation based on their different interactions with the stationary phase.
What role does the stationary phase play in paper chromatography and how does it affect the separation of compounds"?
The stationary phase in paper chromatography acts as a medium for separating compounds based on their different affinities for the stationary phase and the mobile phase. It affects the separation of compounds by slowing down the movement of different compounds at different rates, allowing them to separate based on their interactions with the stationary phase.
What are the key differences between paper chromatography and thin layer chromatography?
Paper chromatography and thin layer chromatography are both techniques used to separate and analyze mixtures of substances. The key differences between them lie in the materials used and the method of separation. In paper chromatography, a strip of paper is used as the stationary phase, while in thin layer chromatography, a thin layer of silica gel or other material is used. Additionally, in paper chromatography, the solvent moves up the paper through capillary action, while in thin layer chromatography, the solvent is applied directly to the stationary phase. Overall, thin layer chromatography is faster and more efficient than paper chromatography, but both techniques have their own advantages and applications in analytical chemistry.
What are the differences between reverse phase and normal phase chromatography?
Reverse phase chromatography and normal phase chromatography are two types of chromatographic techniques that differ in the polarity of the stationary phase and mobile phase. In reverse phase chromatography, the stationary phase is nonpolar and the mobile phase is polar, while in normal phase chromatography, the stationary phase is polar and the mobile phase is nonpolar. This polarity difference affects how compounds interact with the stationary phase, leading to differences in separation and elution times.

The stationary phase in paper chromatography is the paper itself.
What is mobile and stationary phase in Chromatography?
In chromatography, the mobile phase is the solvent that carries the sample through the stationary phase. The stationary phase is the material that interacts with the components of the sample, causing separation based on differences in their affinity for the stationary phase.

What is the difference between the stationary phase and the mobile phase in chromatography?
stationary phase stays at the bottom of the paper chromatography while mobile phase is moving on the stationary phase and move on stationary phase till it gets its right place on the top of the paper or somwhere else.
How many phases are usually involved in the a paper chromatography?
There are typically two phases involved in paper chromatography: the stationary phase (the paper) and the mobile phase (the solvent). The stationary phase is where the separation of components occurs, while the mobile phase moves the sample through the paper to facilitate this separation.
What are the two techniques used in paper chromatography to identify caffeine in tea?
The two techniques used in paper chromatography to identify caffeine in tea are stationary phase and mobile phase. In stationary phase, a sheet of filter paper is used to hold the sample, while in mobile phase, a solvent is used to carry the sample along the paper. These techniques separate the components of the sample based on their affinity for the stationary and mobile phases.
What is absorbent in chromatography?
An absorbent in chromatography refers to the material used to support or hold the stationary phase in the chromatography. It serves to facilitate the separation of components in the sample as they flow through the stationary phase. Common absorbents include silica gel, alumina, and cellulose.

Reverse phase chromatography and normal phase chromatography are two types of chromatographic techniques that differ in the polarity of the stationary phase and mobile phase. In reverse phase chromatography, the stationary phase is nonpolar and the mobile phase is polar, while in normal phase chromatography, the stationary phase is polar and the mobile phase is nonpolar. This difference in polarity affects the retention and separation of compounds in the sample being analyzed.
What are the key differences between normal phase chromatography and reverse phase chromatography?
Normal phase chromatography and reverse phase chromatography are two types of chromatographic techniques that differ in the polarity of the stationary and mobile phases. In normal phase chromatography, the stationary phase is polar and the mobile phase is nonpolar, while in reverse phase chromatography, the stationary phase is nonpolar and the mobile phase is polar.
