Distribution law
Template:Short description Lua error in package.lua at line 80: module 'Module:Hatnote list' not found. Template:Refimprove Distribution law or the Nernst's distribution law[1][2]Template:Better source gives a generalisation[<span title="Script error: No such module "decodeEncode".">clarification needed] which governs the distribution of a solute between two immiscible solvents. This law was first given by Nernst who studied the distribution of several solutes between different appropriate pairs of solvents.
C1/C2 = Kd
Where Kd is called the distribution coefficient or the partition coefficient. Concentration of X in solvent A/concentration of X in solvent B=Kď If C1 denotes the concentration of solute X in solvent A & C2 denotes the concentration of solute X in solvent B; Nernst's distribution law can be expressed as C1/C2 = Kd. This law is only valid if the solute is in the same molecular form in both the solvents. Sometimes the solute dissociates or associates in the solvent. In such cases the law is modified as, D(Distribution factor)=concentration of solute in all forms in solvent 1/concentration of solute in all forms in solvent 2.
