A weak acid titration with a strong base is somewhat different from the titration strong acid by strong base. In the titration of 25 ml of 0.1 mol / L NH3 by 0.1 HCl
mol / L, calculate:
a) the pH before the titration starts
b) the pH at the midpoint of the titration
c) pH without equivalence point
Given away.
Ka: NH4+ = 5.6 x 10^-10
