Titration Key Terms

Aliquot

Portion of a sample solution used for analysis during titration.

Concordant titres

End point

Point at which a colour change occurs during titration

Equivalence point

Point at which the reaction has occurred as per the stoichiometric ratio of the balanced equation.

Indicator

A substance that changes the colour to indicate a pH range

Meniscus

Curves upper surface of liquid.
