 The partition coefficient (logP) is a measure of the equilibrium distribution of a solute between two immiscible liquids, usually water and 1-octanol.

 

When phenol is behaving as the solute with water and 1-octanaol as the solvents its log P value is 30.2. What does this value say about the relative solubility of a phenol molecule in each solvent liquids? Explain your answer with reference to theory covered in the course regarding miscibility and intermolecular forces. [4 marks]

 Note: in the formula above the equilibrium concentration of a solute S in solvent x is denoted as [S]x ( e.g. [S]aq denotes what concentration of a solute is dissolved in the water layer)
