What is the pH of 250.0mL solution that is 0.0955 M HCH3CO2(Ka=1.8x10-5) and 0.125 M NaCH3CO2?
a. Now, 20.0 mL of 0.455 M HCl (aq) is added to the originalbuffer.
i. Write the neutralization reaction (use the actual species inthe reaction).
ii. Find the moles of all species. iii. Build a stoichiometrytable with the reaction and the data (or anything that shows whathappens in the reaction).
iv. What is the pH of the solution? Was your predictioncorrect?
v. Do you still have a buffer? Why?
