Arthur Wen, a CHEM 18.1 student, was tasked to make a 250mL solution of NaCH3COO with pH = 9.022 for their laboratory class. However, he forgot to take note of the initial concentration needed and was too shy to ask Mr. Lee, his teacher. He knows that the conjugate acid of one of the salt's ions has a Ka = 1.8 x 10-5. 1. Compute for the initial concentration (M) of NaCH3COO: M 2. Compute the mass (g) of solid NaCH3COO to prepare the said solution:

You have a solution of the weak acid HA and add some of the salt NaA to it. What are the major species in the solution? What do you need to know to calculate the pH of the solution, and how would you use this information? How does the pH of the solution of just the HA compare with that of the final mixture? Explain.
