Acid: species that donates a proton in aqueous solution.
Accurate titration: carefully performed titration that is carried out after the rough titration is performed.
Alkali: species that accepts a proton in aqueous solution
Concordant titre: the volume of two or more titres that are similar in quantity (less than a 0.10 mL difference between each other).
Dilution: the process of reducing the concentration of a solute in solution, usually by mixing it with more solvent.
End-point: a physical change in the solution as determined by the indicator.
Indicator: a dye or mixture of dye that marks the end-point of the titration.
Titration: a technique to measure the concentration of acid or alkali in a sample, by comparing it to the concentration of alkali or acid in a standard solution
Titre: the total volume of solution added to reach the end-point of the titration.
Rough titration: it is used along with the first titration to get an approximation volume that is needed to reach the end-point.
Standard solution: a solution in which the concentration of solute in mol dm-3 is known accurately.
