Helpppp
If the pH of an acid is plotted against the amount of base added during a titration, the shape of the
graph is caled a titration curve. All acids titration curves follow the same basic shape. At the
beginning, the solution has a low pH and climbs as the strong base is added. As the solution nears the
point where all of the H* are neutralized, the pH rises sharply and then levels out again as the solution
becomes more basic as more OH- ions are added.
The titration curve in Figure 1 shows a strong acid
being titrated by a strong base. There is the initial slow
rise in pH until the reaction nears the point where just
enough base is added to neutralize all the initial acid.
This point is the equivalence point.
