A weak base, ammonia, is to be titrated with hydrochloric acid. A volume of 30.0 mL of the 0.75 M NH3 (weak base) whose Kb = 5.25 x10^-6 is titrated with 0.96 M HCl (strong monoprotic acid). Assuming that the stoichiometry for this neutralization titration is 1:1 , calculate the ff: (A) initial pH of the original solution. (B) the pH of the resulting solution halfway through its equivalence point. (C) pH of the resulting solution when the volume of the added strong acid titrant neutralizes 80% of the analyte.
