Definition: This calculator determines the ratio of partial pressures of two immiscible liquids based on their molar quantities in a mixture.
Purpose: It helps chemists and chemical engineers understand the vapor pressure relationship between two immiscible liquids in a system.
The calculator uses the formula:
Where:
Explanation: For immiscible liquids, the ratio of their partial pressures equals the ratio of their moles present in the mixture.
Details: Understanding this ratio is crucial for distillation processes, vapor-liquid equilibrium calculations, and designing separation systems.
Tips: Enter the number of moles for both liquids. Both values must be greater than 0. The result shows their pressure ratio.
Q1: What are immiscible liquids?
A: Liquids that don't mix to form a homogeneous solution (e.g., oil and water).
Q2: Why does this ratio matter?
A: It determines the composition of the vapor phase above the liquid mixture.
Q3: Does temperature affect this ratio?
A: Temperature affects individual vapor pressures but not their ratio for immiscible liquids.
Q4: Can this be used for miscible liquids?
A: No, miscible liquids follow Raoult's law and require different calculations.
Q5: What's the practical application?
A: Used in steam distillation and designing separation processes for immiscible liquid mixtures.
