Solubility
Solubility of a solid in a liquid
Solubility
Solubility is a physical property of a solution. It can be defined as the measure of maximum amount of solute that can be dissolved in a quantified amount of solvent.
10g of glucose powder soluble in 90 g of water
This property of solution depends upon the factors like:
o The nature of solute and solvent and the interaction between them: The stronger the attractions between solute and solvent molecules, the greater will be the solubility.
o Molecular size of solute: Larger molecules are more difficult to dissolve in solvents whereas the smaller molecules dissolve easily and are more soluble in solvents. o
Polarity: Polar solvents( having bonds with different electro negativities) like Water, ethanol, formaldehyde dissolve polar solutes whereas nonpolar solvents( having bonds with similar electro negativities) like pyridine, toluene, and hexane dissolve nonpolar solutes.
o Temperature: Rise in temperature increases the solubility. o Pressure: Rise in pressure increases the solubility.

Solution of sugar or salt dissolved is a common example of solubility of a solid in liquid. But it is not necessary that all solids will dissolve in liquid.
