. Consider the titration of 15.0 mL of 0.150 M (C2H5)2NH(aq) (Kb= 6.9 x 10-4) with 0.125 M HCl(aq). Calculate the pHat each of the following points and identify which point of titration has been reached (i.e. indicate as buffer region, or half-equivalence point, or equivalence point, or past equivalence point). (a) After addition of 10.0 mL of 0.125 M HCl(aq). (b) After addition of 18.0 mL of 0.125 M HCl(aq). (c) After addition of 19.5 mL of 0.125 M HCl(aq).
