Consider the chemical structure of glutamic acid. Which of the following structures would predominate at pH 12 if you titrated 100ml of 0.10M glutamic acid with 1.0M NaOH?

What is the pH at the equivalence point for the titration between sodium hydroxide and acetic acid?

If you added 4.5ml of 1.0M HCl to 100ml of 0.10M glycine, pH 12.0, what would be the expected (calculated) pH?Note: Assume that at a pH of 12.0, there are 9.96mmol of the base form (NH2) of glycine in solution. The pKa of basic amine functional group (NH2) in glycine = 9.6 and the pKa of the acidic carboxyl group in glycine (COOH) = 2.3.Selected Answer: [None Given]Answers: A. 10.1B. 2.7C. 9.7D. 4.6E. 9.9

A solution of weak acid HA was titrated with base NaOH. The equivalent point was reached when 40 ml. of 0.1 M NaOH has been added. Now 20 ml. of 0.1 M HCl were added to titrated solution, the pH was found to be 5.0. The value of pKa of HA is :

Which of the following solutions has the same pH value as 100 mL of 0.05 M sulphuric aciddiluted to 1L at the same temperature?(A) 10-2 M sodium hydroxide solution (B) 10-2 M calcium hydroxide solution(C) 0.06 M hydrochloric acid solution (D) 0.01 M nitric acid solution
