Buffer region in titration curve
WebFor the titration of a strong acid with a strong base, the equivalence point occurs at a pH of 7.00 and the points on the titration curve can be calculated using solution stoichiometry. Figure 6. (a) The titration curve … WebFor the titration of a weak base with a strong acid, the pH curve is initially basic and has an acidic equivalence point (pH < 7). The section of curve between the initial point and the equivalence point is known as the buffer region. At the half-equivalence point, the concentrations of the buffer components are equal, resulting in pH = pK ...
