18.4.1 Sketch the general shapes of graphs of pH against volume for titrations IB Chemistry HL

Axis intercepts can be used to calculate pka or pkb. Equivalence (inflection) points are the steepest parts of the graph and occur when the chemical reaction is over. A buffered region occurs when a weak acid or base is present with its salt. At half-equivalence the pH = pka of the weak acid, or the pOH = pkb of the weak base. This stuff is tough, eh!
