pH = 5.56 at 36.0 ml(equivalence point)
The purpose of a titration is to find the equivalence point (stoichiometric point) of a solution. At the equivalence point, the moles of the titrant and analyte are equal to one another. At the midpoint of the solution, the pKa value is equal to the pH value.
Coductometric titration: is based on the suddenly change of the conductivity at the equivalence point.Volumetric titration: the volume of a standardized titrant is measured at the eqivalence point.
The equivalence point, or stoichiometric point, of a chemical reaction is the point at which an added titrant is stoichiometrically equal to the number of moles of substance (known as analyte) present in the sample: the smallest amount of titrant that is sufficient to fully neutralize or react with the analyte.
The titrant is the solution involved or used in a titration to determine the concentration of an unknown solution.
Most solutions used in titrations are colorless, therefore you cannot really estimate the equivalence point (the volume of added titrant that causes a stoechiometric reaction). However, slight variations in other factors such as acidity (pH) can be detected by means of an indicator, which will change color accordingly. This will notify you when you have reached the equivalence point.
No. The equivalence point is reached when the moles of titrant equals the moles of analyte.
The chemical process for back titration is to titrate the analyte past the original end point/equivalence point, and then BACK titrate the excess titrant to equivalence.

Analyte: the substance to be analyzed by titration. Titrant: the substance (with a known concentration) added to the analyte solution to perform a titration.
when we do not know nothing about the other titrant.
If we plot the pM (M= concentration of metal ion in the analyte) against the volume of titrant the titration curve takes the sigmoidal shape, plateau in the first part, sharp rise around the equivalence point and then again flat.
direct titration involves the direct and stepwise addition of a standard titrant to the analyte whilst the back titration involves reacting a standard excess titrant wth an analyte solution of an unknown concentration, then reacting the excess (left over) titrant with an analyte of known concentration to determine the concentration of excess titrant.
during a titration when a titrant completely furnished the sample then this is the end point of titration.
