A buffer solution is formed by adding 0.150 moles of solid strontium acetate, Sr(C₂H₃O₂)₂, to 500.0 ml of 0.400 M acetic acid, HC₂H₃O₂ solution. You may assume that the change in volume is negligible upon addition of the solid. Calculate the pH of the buffer solution. Calculate the pH of the buffer solution after the addition of 7.50 ml of 2.00 M NaOH. Acetic Acid: pKa = 4.75 Ka=1.76E-5 M.w.=60.05 g/mol
