Dissolution of solid in liquid
Dissolution is the process of a solid substance dissolving in a liquid to form a solution. In the pharmaceutical industry, dissolution plays a crucial role in drug delivery. It determines the rate at which a drug is released from a dosage form and becomes available for absorption by the body. Therefore, understanding the dissolution of solids in liquids is essential for developing effective drug products. Dissolution Process The dissolution process involves the breaking down of the solid substance into smaller particles that are then dispersed throughout the liquid solvent. The solute particles are surrounded by solvent molecules, and the intermolecular forces between the solute and solvent molecules overcome the intermolecular forces holding the solute particles together, allowing them to dissolve. The process of dissolution can be broken down into several steps: Wetting: The first step is wetting, where the solid surface comes into contact with the solvent. The solvent molecule...
