Question

solvent extraction is governed by which law
​

Answer 1

Answer:

Abstract

AbstractTHE thermodynamic law for the partition of a solute between two immiscible or partially miscible solvents is: a = K a′ where a and a′ are the activities in the two phases, and K is a constant.

Answer 2

Answer:

• As the organic extraction solvent, low polarity organic solvents such hexanes, toluene, dichloromethane, and diethyl ether are typically employed.
• Because these two immiscible (or barely soluble) solvents differ in their solubility or distribution coefficient, a molecule is extracted from one solvent into another during this procedure.
• Solvent extractions are based on the "Rule of Nerst's disintegration." The Nernst's distribution law, often known as the distribution law, provides a generalization that controls how a solute is distributed across two immiscible solvents.
• The thermodynamic equation a = K a′, where a and a′ are the activity in the two phases and K is a constant, describes how a solute is partitioned between two immiscible or partially miscible solvents.
