Distribution Ratio Formula:
From: | To: |
Definition: This calculator determines the distribution ratio of a solute between two immiscible solvents (typically organic and aqueous phases).
Purpose: It helps chemists and chemical engineers understand how a compound partitions between different phases, which is crucial for extraction processes.
The calculator uses the formula:
Where:
Explanation: The ratio compares the solute concentration in the organic phase to its concentration in the aqueous phase at equilibrium.
Details: The distribution ratio is critical for designing extraction processes, predicting solute behavior, and optimizing separation efficiency in chemical and pharmaceutical industries.
Tips: Enter the solute concentration in both organic and aqueous phases. Both values must be > 0. The result is dimensionless.
Q1: What does a distribution ratio greater than 1 mean?
A: A ratio > 1 indicates the solute prefers the organic phase, while < 1 indicates preference for the aqueous phase.
Q2: How is this different from partition coefficient?
A: Partition coefficient refers to a single species, while distribution ratio considers all forms of the solute in each phase.
Q3: What factors affect the distribution ratio?
A: Temperature, pH, solvent composition, and solute chemical properties all influence the ratio.
Q4: What are typical units for concentration?
A: While mol/m³ is used here, other concentration units can be used as long as both phases use the same units.
Q5: How is this used in real applications?
A: It's crucial for liquid-liquid extraction processes in pharmaceuticals, metallurgy, and environmental remediation.
