10.54 grams of zwitterionic form of Cysteine (MW=121.16g/mol) was dissolved in 500mL of water. A 25.0mL volume of this solution was then titrated with 0.500MNaOH. Answer the following questions. (Cysteine: pKa1=1.7,pKaR=8.3,pKa2=10.8 )...Always show your reasoning and calculations (a) How many equivalence points should we expect to be observed during the above titration? Explain in 1-2 sentences. (b) What are the expected main species present at the equivalence points mentioned in part (a) Draw the structures (ChemDraw) and explain. (c) What is the expected starting pH of the solution containing the zwitterion of cysteine? (d) At what volumes of NaOH (during the titration) should we expect to observe the equivalence points? Explain and show any related calculations. (e) At what volumes of NaOH (during the titration) should we expect to observe the pH that is equal to the pKa values? Explain and show any related calculations. (f) Sketch a titration curve for the titration described in your responses above up to the pH of 12
