Concentration Formula:
From: | To: |
Definition: This calculator determines the concentration of a solute in the aqueous phase based on its concentration in the organic phase and the distribution ratio between the two phases.
Purpose: It's essential in chemistry for understanding solute partitioning between immiscible solvents, particularly in extraction processes.
The calculator uses the formula:
Where:
Explanation: The concentration in the organic phase is divided by the distribution ratio to find the equilibrium concentration in the aqueous phase.
Details: Accurate calculation helps in designing extraction processes, predicting solute behavior, and optimizing separation techniques in chemical engineering and analytical chemistry.
Tips: Enter the solute concentration in the organic phase (in mol/m³) and the distribution ratio between the two phases. Both values must be > 0.
Q1: What is the distribution ratio?
A: The distribution ratio (D) is the ratio of the total concentration of a solute in the organic phase to its total concentration in the aqueous phase at equilibrium.
Q2: What units should I use for concentration?
A: The calculator uses mol/m³, but you can use any consistent units as long as both concentrations use the same units.
Q3: How does temperature affect the calculation?
A: Temperature can significantly affect the distribution ratio, so ensure your D value is appropriate for your working temperature.
Q4: Can this be used for any solute-solvent system?
A: This applies to systems where the solute partitions between two immiscible liquid phases following the distribution law.
Q5: What if my solute ionizes in the aqueous phase?
A: For ionizing solutes, you may need to consider the partition coefficient rather than simple distribution ratio.
