How does temperature affect potentiometry
Webperformed at the same temperature as the sample titration, since the temperature influences titrant density. Titrants expand in volume at higher temperatures, and thus their titer factor decreases accordingly. Standardization procedures for the various titrants are described in the Volumetric Solution section of the USP - NF (3). Specificity WebPotentiometric titration belongs to chemical methods of analysis in which the endpoint of the titration is monitored with an indicator electrode that records the change of the …
