This video explains Solubility of a substance is its maximum amount that can be dissolved in a given quantity of solvent. It depends on the nature of solute and solvent. It is also dependent on temperature and pressure. Solubility is defined as the number of grams of the solute that saturates 100 grams of solvent at a given temperature. It has no units. Common salt (or) cane sugar dissolves readily in water but not in benzene. Naphthalene (or) camphor dissolves readily in benzene, but not in water. In general a solute dissolves in a solvent if intermolecular interactions are similar in the two substances. Like dissolves like the principle of solubility. The solubility of a solid or liquid is markedly influenced by temperature. This influence can be explained based on the Chatelier's principle. In a nearly saturated solution, if dissolution process is exothermic (∆H (delta H) solution is negative), solubility decreases with increase in temperature. If the dissolution process is endothermic (∆H solution is positive), solubility increases with increase in temperature.
