(a)

• Let us determine whether the shaking of the separatory funnel causes a change in the partition coefficient Partition coefficient.
• The ratio of a substance concentration in one phase$\left({\mathrm{c}}_1\right)$ to the concentration in a second phase$\left({\mathrm{c}}_2\right)$ when the two given concentrations are considered to be at equilibrium : $K=\frac{c_1}{c_2}$
• The larger the partition coefficient is equal to the less solute (substance) remains in phase 1.
• Hence, we would say that partition coefficient does not get affected by shaking as it only tells us the difference between the solubility of a solute between two solvents.

(b)

• Here, let us explain the purpose of shaking the funnel
• when we do this process of extraction, we have two solvents and one of those solvents is more suitable for a solute
• This would require a physical movement of solute (shaking of the funnel) in order to partition the solute between two liquid phase
• Result:
• Shaking the separatory funnel does not change the partition coefficient and it just separates the solute between two liquid phases.
