You are studying a solution which contains 0.453 mol of CH 3 ? COOH in 430 mL of distilled water. You add 5.2mL of 2.9M HCl. You mix the solution and measure the pH. After which you add 4.2 mL of 1.8 MHCl. pK a ? =4.74 Please answer the following seven (7) questions. Choose the seven (7) most appropriate answers. Question A: After mmixin NaCH3COO and the 2.9MHCl, do you have a buffer? Question B: What is the E line moles for the H+ ? after neutralization has occurred? Question C: What is the species of the weak conjugate acid? Question D: What is the concentration of the weak conjugate acid that is included in the Henderson-Hasselbalch equation? Question E: What is the pH of the solution after the addition of 5.2 mL of 2.9M HCl ? Question F : What is the E line moles for the CH 3 ? COOH after the addition of 4.2 mL of 1.8 M HCl ? Question G: What is the pH of the solution after the addition of 4.2 mL of 1.8 M HCl ?
