What is an aqueous solubility?
An aqueous solubility is an equilibrium partitioning of a compound between its pure phase and water.
What is solubility of pregabalin in organic solvents especially normal phase?
Pregabalin is generally soluble in organic solvents such as ethanol, methanol, and acetonitrile, but its solubility in non-polar organic solvents tends to be limited. In normal phase chromatography, where non-polar stationary phases are used, pregabalin may exhibit lower retention and solubility due to its polar nature. Its solubility characteristics make it more compatible with polar organic solvents rather than typical non-polar solvents used in normal phase conditions.
How does chromatography work to separate particles of ink?
Chromatography works to separate particles of ink by exploiting differences in solubility between the ink components and the mobile phase (solvent). As the mobile phase moves through the stationary phase (usually a paper or column), it carries the ink components at different rates based on their solubility. This differential movement results in separation of the ink particles into distinct bands or spots on the chromatography paper.
How does ice water affect solubility?
Ice water, being at a lower temperature, generally decreases the solubility of many solids in water due to reduced molecular motion, which hinders the dissolution process. For gases, however, colder temperatures can increase solubility as gas molecules are more readily trapped in the liquid phase. Overall, the effect of ice water on solubility can vary depending on the specific solute and its interactions with water.
What property does chromatography depend on?
Chromatography relies on the differences in the affinity of substances for a stationary phase and a mobile phase. Components of a mixture move at different rates through the stationary phase due to their varying interactions, such as adsorption or solubility. This differential migration allows for the separation and analysis of the individual components in the mixture.

What idea will the partition coefficient value give you about the solubility?
The partition coefficient value provides information on how a compound distributes between two immiscible phases, typically between a water phase and an organic phase. A higher partition coefficient value suggests higher solubility of the compound in the organic phase relative to the water phase, indicating greater hydrophobicity and potential difficulty in aqueous solubility. On the other hand, a lower partition coefficient value suggests higher solubility in the aqueous phase relative to the organic phase.
Is solubility a phase change of matter?
Solubility is not a phase change of matter. It refers to the ability of a substance (solute) to dissolve in a solvent to form a homogeneous mixture (solution) without changing its chemical composition. It is a physical property and does not involve a change in the phase of the substance.
What is complete solubility in relation to thermal equilibrium diagrams for alloys?
Field of one phase (compared to two phase field, etc)

What is liquid used in chromatography called?
The liquid used in chromatography is called the mobile phase. It is responsible for carrying the sample through the stationary phase, allowing for the separation of components based on different properties like solubility and polarity.

How would solubility of SO2 change as temperature increases?
As temperature increases, the solubility of SO2 in water decreases because gases are less soluble in hot water compared to cold water. This is due to the higher kinetic energy of gas molecules at higher temperatures, which makes it easier for them to escape the liquid phase.
How does the solubility of a gas change with increasing temperature?
solubility generally increases with a temperature increase
What separates substances based on their movement through a special paper?
Chromatography separates substances based on their differing abilities to dissolve in a mobile phase (usually a liquid or gas) and adhere to a stationary phase (such as special paper). As the mixture is carried along by the mobile phase, components with stronger affinity for the stationary phase will move slower, leading to separation based on their solubility and adsorption properties.
