Calculate the pH at the following points in a titration of 40 mL … WebA conjugate acid-base pair is a pair of substances that differ by one H+ ion. For example, HCl and Cl− are a conjugate pair where HCl is the acid and Cl− is the base. Similarly, NH3 and NH4+ are a conjugate pair where NH4+ is the acid and NH3 is the base. Note that the acid in each pair has more H atoms and the higher charge.

http://www.shodor.org/unchem/basic/ab/ WebA strong base ($\ce{KOH}$) reacts with a weak acid ($\ce{HF}$) at stoichiometric ratio: $$\ce{KOH + HF -> H2O + F- + K+}$$ The major species is fluoride, a weak base with pKb = 14 - pKa, where pKa is that of hydrofluoric acid. The potassium ion is a spectator. To find the pH, use your favorite strategy for a pure weak base. The result is pH = 8.14.
