Cоnsider а buffer sоlutiоn thаt is 0.400M butаnoic acid (CH3CH2CH2COOH) and 0.500M sodium butanoate. Ka (butanoic acid) = 1.61 x10-5 Calculate the [H+], [OH-], pH, and pOH for this buffer. (12 pts) Calculate the pH of this buffer after adding 22.0 mL of 2.2M NaOH to 1.0 L of the solution (Hint: 1.0 L + 22 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.
