For the next three problems, consider 1.0 L of a solution whichis 0.6 M HC2H3O2 and 0.2 MNaC2H3O2 (Ka forHC2H3O2 = 1.8 x 10-5).Assume 2 significant figures in all of the given concentrations sothat you should calculate all of the following pH values to twodecimal places.
1. Calculate the pH of this solution.
2. Calculate the pH after 0.10 mol of HCl has been added to theoriginal solution. Assume no volume change on addition ofHCl.
3. Calculate the pH after 0.20 mol of NaOH has been added to theoriginal buffer solution. Assume no volume change on addition ofNaOH.
