LC Chem 4.3 Acid-Base titrations
A solution of precisely known concentration
A substance which can be obtained in a stable, pure and soluble solid form so that it can be weighed out and dissolved in water to give a solution of accurately known concentration.
A laboratory procedure where a measured volume of one solution is added to a known volume of another solution until the reaction is complete.
The stage in the titration when the two solutions just react completely with each other
The stage in the titration when the equivalence point is shown by an indicator
