Titration curve: a graph of volume of base vs. pH, when an acid is titrated with the base.
We can also obtain titration curves for volume of ACID added to base, but we will omit those this term.
Three types of titrations
Equivalence Point: the point at which the moles of acid = the moles of base.
The pH is initially very low (only strong acid present).
Any titration curve can be considered to have four parts.
Initial pH: before base is added.
Acid range: the moles of acid > moles of base. The pH depends on the molarity of the EXCESS moles of acid.
Equivalence point: for strong acid- strong base, the pH=7
Base range: beyond equivalence point.
Indicators are weak acids.
