The dissolution process is the process by which solute molecules disperse within a solvent to form a solution. Dissolution occurs when a solute disperses in a solvent and a solution forms when dissolution is complete.
Importance of Dissolution Profiles
Dissolution profiles help assure product performance despite production changes. Friability testing checks tablet durability during shipping.
Understanding the Dissolution Process
The dissolution process involves three steps: separation of the solute particles, separation of the solvent particles, and combining the separated solute and solvent particles to form a solution.
Factors Influencing Dissolution
Intermolecular interactions influencing dissolution depend on solvent-solute factors, not just solute polarity.
Examples of Dissolution
Salts dissolve as ions or ion groups based on concentration. Companies dissolve by ending corporate status after assets distribute.
Spontaneous Solution Formation
Spontaneous solution formation depends on whether dissolution absorbs or releases energy. Some compounds dissolve exothermically, others endothermically.
Example of a Dissolution Process
Dissolution is the process where solutes dissolve into solvents to form solutions. It happens when attraction between solvent and solute particles overcomes attraction between solute particles.
Weathering and Dissolution
Weathering breaks down or alters rocks to become sediment. Dissolution, the most observable chemical weathering, happens when minerals dissolve into a liquid.
Solvent and Solution Examples
Dissolving substances into solvents makes solutions. Common solvents are water and air. Examples are gases into gases, solids into liquids, liquids into solids, or gases. Specific combinations depend on the substances and their states of matter.
