Distribution Coefficient Formula:
From: | To: |
Definition: The Distribution coefficient is the concentration of solute in two different phases (solid and liquid in this case).
Purpose: It helps in understanding how impurities distribute between solid and liquid phases during processes like doping or purification.
The calculator uses the formula:
Where:
Explanation: The ratio shows how the impurity partitions between the solid and liquid phases.
Details: Understanding the distribution coefficient is crucial for material science, purification processes, and semiconductor manufacturing.
Tips: Enter the impurity concentrations in both solid and liquid phases. Both values must be > 0.
Q1: What does a high distribution coefficient mean?
A: A high kd means the impurity prefers the solid phase over the liquid phase.
Q2: What's a typical range for distribution coefficients?
A: Values can range from near 0 (prefers liquid phase) to very high numbers (prefers solid phase).
Q3: How does temperature affect the distribution coefficient?
A: Temperature can significantly affect kd as solubility in different phases changes with temperature.
Q4: Can kd be greater than 1?
A: Yes, when the impurity concentration is higher in the solid than in the liquid.
Q5: How is this different from partition coefficient?
A: While similar, partition coefficient typically refers to distribution between two immiscible liquids.
