|
concentration
|
A measure of how much solute is dissolved in a unit quantity of solution.
|
|
|
concordant titres
|
Titres that vary within narrowly specified limits.
|
|
|
conical flask
|
A flask with a broad base and narrow neck, used in titrations.

|
|
end point
|
The point during a titration when the indicator changes colour.

|
|
equivalence point
|
A point during a titration when the solutions have been mixed in the mole ratio shown by the reaction equation.

|
|
indicator
|
A substance that has different colours in acidic and basic solutions.
|
|

|
|
|
primary standard
|
A substance that is so pure that its amount (in mole) can be determined accurately from its mass.
|
|
|
standard solution
|
A solution of accurately known concentration.
|
|
|
titration
|
A process used to determine the concentration of a reagent in which one solution is added from a burette to a known volume or mass of another substance.
|
|
|
titre
|
The volume of liquid, measured by a burette, used in a titration.
