Heavens no. Every substance has its own unique solubility constant.

What is the solubility of 2-mercaptobenzimidazole?
It depends on the solvent you intend to use. In water its solubility is negligible. In Acetone, Ethyl Acetate ist high, in alcohol it is soluble as well though not to the same extent.
What happens to the solubility of solids such as KNO3 when temperature of the water rises?
KNO3 and NaClO3 have the same solubility at approximately 95 Celsius. NaClO3 can be more soluble than KNO3 at different temperatures, but it is not seen that KNO3 is more soluble than NaClO3.
What is the saturation temperature of vapour or the boiling temperature of a liquid?
Different liquids have different boiling temperatures, even the same liquid will have different boiling temperatures at varying pressures.
Would you expect RF number of a pigment to change if we altered the composition of the solvent why or why not?
No, the solubility of the pigment molecule in its organic solvent is a factor involved in the separation of pigments. More soluble molecules move faster and generally travel further. Chlorophyll B is a great example since its only soluble in fat solutions.
What is the effect of temperature and stirring on solubility of sugar?
These effects are the same when dissolving anything into anything. Stirring, or motion, is the key. Stirring plays a role because it is motion in the solvent at the macro level. The temperature of the solvent (water) plays a role because the higher the temperature the more motion in the volume at the molecular level.
What are the properties of an ideal recrystallization solvent?
1) It will have a boiling point that is lower than the melting point of the solid being recrystallized; 2) The compound will be soluble in the boiling solvent but have poor solubility in the same solvent after cooling; 3) Small amounts of impurities present in the crude solid will be soluble in the chosen solvent at any temperature
What is the difference between saturation and solubility?
Saturation and solubility is the same. They both meant to point out the maximum of solute dissolved through out the solvent.
How is solubility related to temperature?
This relationship is most often observed when dealing with liquid solutions. The solubility of solids and liquids in a liquid solvent tends to improve as the solvent's temperature increases, while the solubility of gases in the same type of solvent generally decreases as its temperature rises.

Is solubilty the same as a chemical Change?
Solubility is forming of chemical bonds between solute molecules and solvent molecules, hence a chemical reaction.
What do the Rf values indicate about the relative solubility of the pigment in the the solvent?
The Rf values do not indicate the solubility of a substance. The Rf value or retardation factor is the ratio of the distance traveled by the center of a pot to the distance traveled by the solvent front in chromatography.
Would you expect the Rf value of a pigment to be the same if a different solvent were used Explain?
The Rf value would not be the same for every solvent as there are factors that allow each solvent to be unique. The attractive force, particle size and solubility of each solvent will create different results each time.
Is solubility a physical or chemical propety?
Solubility is a physical property because it is related to a physical, not a chemical, change. When something dissolves, it does not change chemically. It is still the same compound/molecule, etc. when it was not dissolved in the solvent.

KNO3 and NaClO3 have the same solubility at approximately 95 Celsius. NaClO3 can be more soluble than KNO3 at different temperatures, but it is not seen that KNO3 is more soluble than NaClO3.
What is the saturation temperature of vapour or the boiling temperature of a liquid?
Different liquids have different boiling temperatures, even the same liquid will have different boiling temperatures at varying pressures.
What affects the solubility of a substance in water?
temperature, pressure, presence of other chemical species (for the same solute and the same solvent)
