Cоnsider а buffer sоlutiоn thаt is 0.500M formic аcid(HCOOH) and 0.400M sodium formiate. Ka (formic acid) = 1.67 x10-4(10 pts) Calculate the [H+], [OH-], pH, and pOH for this buffer. (12 pts) Calculate the pH of this buffer after adding 27.0 mL of 2.2M NaOH to 1.0 L of the solution (Hint: 1.0 L + 27 mL = 1.0 L according to the rules of addition for s.f.).(2pts) To receive full credit, show all work in handwriting or use the software showing calculations and units properly and clearly.
