Acid-Base Titrations

Acid-Base Titrations. Section 17.3. Introduction. Definition: In an acid-base titration , a solution containing a known concentration of a base is slowly added to an acid. An indicator is used to signal the equivalence point of the titration.

Polyprotic Acids

Polyprotic Acids. Interesting Features of a plots. First, notice that the pH where two species concentrations are the same is around the pKa for that equilibrium. In fact, for polyprotic acids with pKa 's that differ by over 3 to 4 units, the pH is equal to the pKa.

Auto-ionization of water and pH

Auto-ionization of water and pH. Monday, April 16. Weak Acids. Most acids are weak and only partially ionize. HA (aq) + H 2 O (l) ? H 3 O + (aq) + A - (aq) or simply our equations: HA (aq) ? H + (aq) + A - (aq) You can eliminate the H 2 O cuz of the (aq) behind HA, and
