Homework Answers
Liquid liquid extraction involves separating compound from the liquid using some immiscible liquid. The extraction of compound depends on the comparative solubility of compound in both the liquids.
Correct option is B

An experiment performed using solid to liquid extraction, liquid-liquid extraction, heating, and recrystallization to isolate caffeine, was not totally successful due to their being very little to no product of caffeine left when the time came to recrystallize the pure caffeine. During the experiment what could of caused there to be not enough caffeine to recrystallize it? ethyl acetate was used as the organic solvent hexane and acetone was used to recrystallize the crude caffeine, through mixture and boiling. Could...

Experiment 9 Acid-Base Extraction Liquid-liquid extraction utilizes the contrast solubilities of solutes in two immiscible solvents the separation of a mixture. An extracting solvent can be reactive that changes the character of solute. Consider a mixture of organic acid, organic base, and neutral substance, for example, benzoic acid, aniline, biphenyl, nd phenol. They sodium benzoate. Sodium hydroxide changes phenol to sodium phenoxide. Hydrochloric acid changes aniline to...

Acid/Base Extraction Liquid-liquid extraction is a technique that can be used to physically separate two substancesthat have varying solubility properties. Typically an aqueous solution can be extracted with anorganic solvent to isolate a compound or vice-versa. The specialized piece of glassware that isemployed for these types of separations is called a separatory funnel.In this experiment a mixture of benzoic acid and naphthalene will be purified using liquid-liquidextraction, more specifically an acid-base extraction. Since both compounds are soluble inethyl acetate (an...
