WebThe solubility of the former type is mainly limited by a strong crystal lattice, making it difficult for the compound to dissociate from the solid form. Such brick dusts are high melting point crystalline solids (T m > 200 °C) in which strong intermolecular bonds within the crystal lattice overcome the competing pull of solvation by water. WebThermodynamic (or equilibrium) solubility investigates the solubility of a compound as a saturated solution in equilibrium. Determining solubility in simulated gastric and intestinal fluids (SGF and SIF, respectively) can give an indication if solubility in the Gl tract is a limiting factor for oral absorption.² flirting with fido reviews
