Volumetric and potentiometric titration

Recommended Posts

what is the difference between volumetric tiration and potentiometric titration.

 

-Volumetric titrations are conducted with understanding of the stoichiometry of that particular reaction. Remember that:

 

[math] (moles)=(molarity)(volume)[/math]

 

So if a known volume of a titrant of known concentration is used to titrate a known volume of analyte of unknown concentration. The concentration of analyte can be determined. Endpoints of the titrations are often found with color changing indicators or UV/vis spectroscopy.

 

-Potentiometric titrations are similar, but the endpoint of the titration is found with potentiometry (measuring of potentials in a chemical redox reaction). This only applies to reactions where something is being oxidized and something is being reduced; meaning electrons are being transferred between distinct chemical species in that reaction.
