The document discusses various types of acid-base titrations, including the neutralization curves that represent the pH changes during a titration with different acid-base combinations. It highlights the significance of the neutralization curve in determining the visibility of the endpoint and selecting appropriate indicators. Additionally, it emphasizes that the choice of indicator must align with the pH of the equivalence point in the titration.

Neutralization curve
A neutralization curve is a plot of the pH of a solution as a
function of the volume of a titrant added during an acid-base
titration. The shape of the curve depends on the strength of the
acid and base involved, as well as the concentration and volume
of the solutions being titrated.
The curve is useful in:
1- Determining whether a sharp end point can be observed or not, this is
indicated by characteristic inflection of the curve.
2- To choose the suitable indicator.
The suitable indicator is that having transition interval(its range)
at pH of equivalence point.
