Consider a buffer solution that is 0.550M propionic acid(CH3CH2COOH ) and 0.400M sodium propanoate. Ka (propionic acid) = 1.34 x10-5 Calculate the , , pH, and pOH for this buffer.(12 pts) Calculate the pH of this buffer after adding 28 mL of 2.0M NaOH to 1.0 L of the solution (Hint: 1.0 L + 28 mL = 1.0 L according to the rules of addition for s.f.).(2 pts) To receive full credit, show all work in handwriting or use the software showing calculations and units properly and clearly.
