Concentration Formula:
From: | To: |
Definition: This calculator determines the equilibrium molar concentration of a solute in the first phase based on its concentration in the second phase and the distribution coefficient.
Purpose: It's essential for chemical engineering, pharmaceutical sciences, and environmental chemistry to understand solute partitioning between phases.
The calculator uses the formula:
Where:
Explanation: The concentration in the first phase is directly proportional to its concentration in the second phase, with the distribution coefficient as the proportionality constant.
Details: Accurate calculation helps in designing separation processes, drug formulation, and environmental remediation.
Tips: Enter the distribution coefficient and solute concentration in solvent2. Both values must be positive numbers.
Q1: What is the distribution coefficient?
A: It's the ratio of solute concentrations in two immiscible solvents at equilibrium.
Q2: What units should I use?
A: Concentrations should be in mol/m³. The distribution coefficient is dimensionless.
Q3: Does temperature affect the calculation?
A: Yes, the distribution coefficient is temperature-dependent. Use values measured at your working temperature.
Q4: Can I use this for gas-liquid systems?
A: Yes, if you have the appropriate distribution coefficient for your system.
Q5: What if my solute concentration is very low?
A: The formula works across concentration ranges as long as the distribution coefficient remains constant.
