Sometimes emulsion is formed during extraction which prevents the two layers from separating. List two things that may cause emulsion formation.
Homework Answers
Emulsion is a mixture containing two or more liquids that completely immiscible to each other but due to some external factors, one liquid is dispersed into another.
Examples include oil and water.
Emulsions are formed when two or more liquids are agitated. This results in breaking down of particles and promoting dispersion.
Emulsion can also be formed using emulsifiers.these are the substance which helps in breaking down the particles promoting dispersion of one immiscible phase to another.

Acid/Base Extraction
ACID/BASE EXTRACTION Provide a flow chart detailing the acid/base extraction/separation of the compounds shown below. Your answer must employ the following reagents: methylene chloride, hydrochloric acid (1M & 6M), sodium hydroxide (1M & 6M), 10% sodium bicarbonate (aq). Clearly indicate the product(s) and layers formed following each step of your separation scheme. HINT: phenol is soluble in sodium hydroxide solution but insoluble in neutral water or sodium bicarbonate solution. Benzoic acid is soluble in both sodium hydroxide and...

Sometimes, objects that are very close to each other cannot be "resolved" - i.e. distinguished as different sources of light. In the assigned reading for this lecture, an equation ("Rayleigh's Criterion") was found that allows us to calculate when two objects may be resolved. Which of the following options describe correct physical properties or specific assumptions that were used to find this equation? (Choose all correct options. Unlimited, unpenalized attempts are allowed.) Light from the sources passes through some circular...

What are some current things in your life that may cause you stress (both good and bad)? List two activities or habits that you currently engage in when you are stressed. What are two additional stress management techniques that you would be interested in participating in within the next six months to reduce your stress? Describe three reasons why stress management is important for your overall health and wellness.

Molecule G is a four carbon molecule which is formed from the Molecule F a tricarboxylic acid after it has gone through oxidative decarboxylations to yield G during citric acid cycle. Molecule F is formed from Molecule E which in turn is formed from Molecules C and D condensation. Molecule C is formed from the oxidative decarboxylation of Molecule A and Molecule D is formed from the oxidation of Molecule X. 1. Molecule X is: A. Alpha-ketoglutarate B. Oxaloacetate C....

sometimes during the initial recovery from a heart attack, the patient enters the so-called oliguric phase of acute renal failure when little urine is produced. A few days later, the patient may leave the oliguric phase and enter a briefer diuretic phase in which a large volume of dilute urine is produced. This is typically a sign of a recovering kidney, although kidney function is not yet normal. What kidney function has recovered at this time, and what function is...
