Consider the titration of 20 mL of .105M Butric Acid HBut, with .125M sodium Hydroxide?
calculate the pH before titration
calculate the volume of added base to reach the end point
calculate the pH halfway to the equivalence point
kb(But-)= 6.6x 10^-10 and ka(HBut)= 1.5x 10^-5
calculate the pH after adding 5ml of NaOH beyond equivalence point
