Solubility of Substance and Crystallization

Things to remember

• The solubility of a substance (solute) at a given temperature is defined as the amount of substance (solute) dissolved in 100 gm. of solvent to make a saturated solution at that temperature.
• A curve obtained by plotting the solubility of substances at different temperatures against these temperatures is known as solubility curve.
• Crystals are the granular substances having sharp edges and smooth surface.
• The process in which crystals are formed by cooling a hot saturated solution of solid materials is called crystallization.
• Those solid substances, which do not have any definite geometrical forms or shapes, are called amorphous solids.
• Those solid substances, which have definite geometrical forms or shapes, along with definite and rigid morphology, are called crystalline solids
