TITRATION GRAPHS;
Titration graphs contain curves which indicate the pH value of the analyst against the volume of
the titrant added as the titration continues.
1. From the provided question, we are supposed to use the analyte which is Hydrochloric
Acid (HCL) 0.1mol/dm3 against a titrant which is a weak base; NH3 0.0758mol/dm3
From the above curve we can see that, before any amount

ammonia is added, the pH is low as it contains H3O+ which is obtained from the
dissociation of the Hydrochloric acid.
HCL + H2 O H3O+ + CL-
Later on as the ammonia is added drop by drop from the burette, the ions of H3O+
are slowly taken away by the ammonia being added. Hence, this is the pH value
which is recorded just as the color change is observed, rather just before the
complete neutralization has taken place.
