A) Calculate the pH of a buffer that is 0.225MHC2H3O2 and 0.162MKC2H3O. The Ka forHC2H3O2 is 1.8x10-5
B) A 1.00L buffer solution is 0.250M in HF and0.250M in NaF. Calculate the pH of the solution after the additionof 0.100 moles of solid NaOh. Assume no volume chane uon theaddition of base. Ka for HF= 3.5x10-4
C) A 100.0ml sample of 0.20M HF istitrated with 0.10M KOH. Determine the pH of the solution after theaddition of 100.0mL of KOH. The Ka of HF is 3.5x10-4
