3. (20 pts) The different behavior of phenol and benzoic acid with sodium hydroxide and sodiumbicarbonate can be used to separate them using an acid-base extraction.. Draw a flowchart for theseparation of benzoic acid and phenol using an acid-base extraction. Assume you havedichloromethane, aqueous sodium hydroxide, aqueous sodium bicarbonate, aqueous hydrochloricacid, and drying agent, and any necessary equipment available. Include enough detail so thatsomeone in your class could perform the extraction you designed.

Tyrosine came from the Greek word "tyros" which is the Greek word for cheese as it was discovered in cheese by Justus von Liebig, a German chemist in 1846. Tyrosine serves as the precursor for dopamine - the neurotransmitter which is considered as the "reward or pleasure molecule" in our brain. It is also involved in controlling the fine motor movement of our muscles such as those of our hands. Draw the titrimetric profile of tyrosine and calculate its isoelectric pH. Note: The aromatic hydroxyl group is titratable.
Titration of a polyprotic acid 4. L-ornithine is a metabolic intermediate in mammals. It is involved in the Urea Cycle, the process by which animals remove nitrogen wastes from the body. L-ornithine is also used as a nutritional supplement, with alleged benefits such as decreasing fatigue, enhancing wound healing and reducing anxiety. L-ornithine contains 3 ionizable groups, x, y & z, with the following pKa’s (pKax = 10.76; pKay = 8.69; pKaz = 1.71). The structure of L-ornithine in the fully protonated form is shown below. Let us analyze the acid-base behavior of L-ornithine. x +H3N L-ornithine NH3+ у OH Z
