Titration Stoichiometry

titration

determine the unknown concentration of a solution

titrant

• solution in the burette

• concentration of this solution is almost always known

• volume referred to as the ‘titre’

Neutralization Reactions

• double replacement reaction

• strong acid reacts with a strong base

• produce water and an ionic compound

Strong Acid/Strong Base Titration Curves

graph that shows the relationship between pH changing against the volume of titrant added

Analyte

• solution reacting with titrant in Erlenmeyer flask

• almost always unknown

End Point

point when there is a sudden change in some observable property of the solution

Equivalence Point

• exact theoretical chemical amount of titrant added

• pH = 7

Indicators

• Substances that change colour in solution when the acidity changes

• end point

formula solution stoichiometry

(concentration/1) x (volume/1) x (mole ratio/mole ratio) x (1/volume)
