We used dichloromethane to perform a liquid-liquid extraction to pull Eugenol out of our water distillate. Briefly describe how a liquid-liquid extraction works.

Expert Solution

Liquid–liquid extraction is also known as solvent extraction, which is a technique to separate compounds based on their relative solubilities in two different immiscible liquids. Commonly water and an organic solvent (ethylacetate, CHCl3, CH2CL2, diethylether and so on).

In this process a substance is extracted from one liquid into another liquid phase. Liquid–liquid extraction is a basic technique in chemical laboratories, where it is performed using a apparatus known as separatory funnels to counter current distribution equipment. This process is employed in laboratory after the reaction is over and is known as workup.

Liquid-liquid extraction depends on the distribution coefficient or distribution ratio. Distribution ratio is often quoted as a measure of how well-extracted a species is. The distribution ratio (K_D) is equal to the concentration of a solute in the extracting solvent (organic phase) divided by its concentration in the (solvent containing the compound) aqueous phase.

In lab we did a liquid-liquid extraction using a separatory funnel - but i don't really understand what was happening ( i just followed directions given) - now my lab report asks me to describe 1. the concept of liquid liquid extraction and how it works 2. Describe how adjusting the pH of the aqueous phase as a means of altering solublity properties of compounds is used in extractions?? can anyone help me understand these two questions above.

1. Why organic solvent is often used in liquid-liquid extraction? 2. Name the adverse effects which occur when a trayed absorption tower operates at too high and too low vapor flow rate? 3. Component separation involving two or more phases (regardless of technique) occurs because systems want to achieve equlibrium and as a result, mass transfer occurs. In a scenario where this mass transfer is particularly slow, would it be more accurate to model a system based on phase equlibrium...

When liquid water is poured onto a flat plate of glass, it spreads out, while liquid mercury forms spherical beads under similar circumstances. Explain the difference in behavior of the two liquids by filling in the blanks in the following statements: The attractions between the water molecules and the glass are _____ than the attractions among the water molecules themselves, so the water spreads out. The attractions among the mercury atoms are _______ than the attractions between the mercury atoms...

To determine the molar mass of a volatile liquid, we used the Dumas method with a test tube, tin foil cover, and hot water bath to convert the liquid to a gas and then measure its pressure, temperature, amount, and volume. a) Why must you leave the test tube in the hot water for several minutes before taking a reading and removing it? What is happening during this time? b) How was the experiment designed to ensure the pressure of...
