2. Calculate the pH at the equivalence point when 75,0 mL of 0.250 M HCl is mixed with 0.350 M of CH3NH2. Kb = 4,4 x 10-4. Your answer must include a balanced equation for the new equilibrium established, completed ICE box, and assumption check 3. A buffer was prepared by mixing 1953 g NaF and 10.419 HF in a 10 L reaction vessel. Ka - 71 x 10-4 a Calculate the moles of NaF b Calculate the moles of HF c. Determine the pH of the butter. d. Determine the pH of the buffer after 0.0525 mol of NaOH has been added. (Your answer must include a completed ICE box)
