What is the moving solvent called in chromatography?
The moving solvent in chromatography is referred to as the mobile phase. It carries the sample through the stationary phase, allowing for separation based on differences in affinity between the components of the sample.
What is volatile solvent?
A solid that can easily tranform into a gas.
How and why did Rf values differ for each solvent system?
The Rf value is calculated by dividing the distance a compound travels by the distance the solvent front travels. Different solvent systems have varying polarities which can affect the interaction between the compound and the stationary phase, resulting in different distances traveled by the compound. Therefore, the Rf values differ for each solvent system due to the varying affinities between the compound and the stationary phase in different solvent environments.
What purpose is the developing solvent used?
The developing solvent is used in chromatography to separate and visualize the components of a mixture. It carries the sample along the stationary phase, allowing different compounds to move at different rates based on their interactions with the solvent and 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.
What phase of matter can act as a solvent?
The liquid phase of matter can act as a solvent. In this phase, molecules have enough energy to move around and interact with other substances to dissolve them.

What is the solvent and solute of sugar water?
the solvent is the water; while the solute is the sugar
Mobile phase in relation to chromatography?
a moving or mobile phase is a mixture you want to separate , dissolved in a solvent.
What would happen if is not soluble in the solvent?
If a solute is not soluble in a particular solvent, it will not dissolve and will remain as a separate phase in the solvent. This can result in the formation of a suspension or precipitate, depending on the nature of the solute and solvent.
What forms when one substance is insoluble or does not dissolve in a solvent?
When a substance is insoluble or does not dissolve in a solvent, it forms a separate phase. This can be in the form of a solid settling at the bottom (sedimentation), particles suspended in the solvent (suspension), or a separate layer on top (immiscibility or phase separation).
What is volatile solvent?
A solid that can easily tranform into a gas.

What are mobile phase and stationary phase?
stationary phase is the solid called the filter paper and mobile phase is the liquid or organic solvent present in the developing tank or beaker by ayesha zulfiqar
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.
Is a water a universal solvent?
Water is a tremendously versatile solvent, and is often described as the closest thing that we have to a universal solvent. But no, it does not dissolve everything. The answer is NO, so therefore WATER IS NOT A UNIVERSAL SOLVENT ! And the most important characteristic of water as a solvent is that water has a polar molecule.
