Clues

  • Adding an electrolyte to an aqueous solution of a non-electrolyte, decreasing the solubility of the non-electrolyte (7, 3)
  • An ion that is already contained within a solution and increasing its concentration leads to a decrease in solubility (6, 3)
  • The conditions where absorption is faster than dissolution, and C (conc of bulk solution) doesn't exceed 10% of Cs (conc of solution at solid/solvent boundary) (4, 10)
  • The general name of a water-miscible solvent that is added to alter the polarity of another solvent to ultimately increase its solubility (2, 8)
  • The mixing of two crystalline solids together which results in a mixture that has a lower melting point than either of the components individually (9)
  • The process of the removal of a solute molecule from a solid, the creation of a cavity in a solvent, and the insertion of the solute molecule in the cavity (11)
  • The solvates recrystallise into a new form when the solvent is removed (11, 8)
  • What is the interaction of a poorly soluble drug with a soluble material to form a soluble macromolecular complex called? (must also be reversible) (12)
  • What is the name of hollow cylindrical molecules in a cyclic arrangement where part or all of the drug molecule is inserted into the hollow central cavity of the molecule? (13)
  • What is the solubility of a drug when completely unionised (S0)? (9, 10)
