Solubility & Solution
- 1. Sojar college of Pharmacy, Khandvi S.Y.B.Pharm SEM:III Physical Pharmaceutics-I Solubility & Solution Presented by Mr. S.D. Modekar
- 2. Solubility & solutions Objectives After completion of this topic, the student should be able to: Understand the terms of solubility. Solubility of substances in solutions & various types of solutions.
- 3. Solubility solubility is the ability of one substance to fully dissolve in another substance under specified condition. Solute is the dissolved agent. (less part of the solution ) Solvent is the component in which the solute is dissolved (more part of the solution).
- 4. Solubility In a quantitative way: it is the concentration of solute in a saturated solution at a certain temperature. In a qualitative way: it is the spontaneous interaction of two or more substances (solute & solvent) to form a homogeneous molecular dispersion
- 5. Solution is a mixture of two or more components that form a homogenous mixture.
- 6. Saturated solution: A solution that contains the maximum amount of solute at a definite temperature Unsaturated solution: is one containing the dissolved solute in a concentration below that necessary for complete saturation at a definite temperature. Supersaturated solution: contains more of the dissolved solute than it would normally contain in a saturated state at a definite temperature
