Amino acids are an important group of compounds. At low pH, both the carboxylic acid group (CO2H) and the amine group (NHR) are protonated. However, as the pH of the solution increases (say, by adding base), the carboxylic acid proton is removed, usually at a pH between 2 and 3. In a middle range of pHs, therefore, the amine group is protonated, but the carboxylic acid group has lost the proton. (This is called a zwitterion.) At more basic pH values, the amine proton is dissociated. What is the pH of a 0.20 M solution of alanine hydrochloride, [NH3CHCH3CO2H]Cl?
Calculate the percentages of dissociated and undissociated forms present in the following solutions: (a) 0.0010 M glycolic acid (HOCH2CO2H; pKa = 3.83) at pH = 4.50 (b) 0.0020 M propanoic acid (pKa = 4.87) at pH = 5.30

A solution is made by dissolving 15.0 g sodium hydroxide in approximately 450 mL water. The solution becomes quite warm, but after it is allowed to return to room temperature, water is added to bring the volume to 500.0 mL of solution. (a) Calculate the pH and pOH in the final solution. (b) Why would we wait for it to return to room temperature? (c) If the mass of the water used to initially dissolve the sodium hydroxide were exactly 450 g and the temperature of the water increased by 8.865 C, how much heat was given off by the dissolution of 15.0 g of solute? Assume the specific heat of the solution is 4.184 J/g. K. What is the molar heat change for the dissolution of sodium hydroxide (known as the enthalpy of solution, Hsol)?
14. A so-called PBS buffer (phosphate buffered saline) is prepared by according to the given protocol: ● Prepare 800 mL of distilled water in a suitable container; ● Add 8 g of NaCl to the solution; Add 200 mg of KCl to the solution; Add 1.44 g of Na₂HPO4 to the solution; Add 245 mg of KH₂PO4 to the solution; Adjust solution to desired pH (typically pH ≈ 7.4); and Add distilled water until volume is 1 L. (a) Calculate the pH of the initial solution (before pH is adjusted). (b) How many moles of acid or base are required to adjust the pH to 7.4?
CHEMWORK Consider a buffered solution containing CH2NH3C1 and CH;NH,. Which of the following statements are true concerning this solution? (K, for CH,NH,* = 2.2 x 10-11). (Select all that apply.) If [CH;NH,] = [CH3NH;], then pH = 3.36 If [CH3NH2] > [CH;NH3], then pH is larger than the pK, value. O A solution consisting of 2.5 M CH3NH;Cl and 2.5 MCH3NH2 would have a higher capacity than one containing 0.5 M CH;NH,Cl and 0.5 MCH;NH,. D A solution consisting of 0.10 M CH;NH;Cl and 0.10 MCH;NH, would have a higher capacity than one containing 1.0 M CH;NH3C1 and 1.0 M CH;NH2. O If NaOH were added to the initial buffered solution, then the [CH;NH,] would increase. Submit Show Hints Submit Answer Try Another Version 9 item attempts remaining
