Scope of thermometric titration

Thermometric titration is a very versatile determination method and an ideal complement to potentiometric titration. In principle it is suitable for any reaction that produces a sufficiently large temperature change in the sample solution. It is particularly suitable for applications

• for which no suitable potentiometric sensor is available,
• for which no suitable reference electrode is available,
• in which the sample affects the indicator electrode or destroys it,
• for which no solvent is available that is suitable for potentiometry.

Typical applications of thermometric titration

Examples

• Determining the free fatty acid (FFA) content in olive oil (pdf, Metrohm Information 2/2006)
• Determining the phosphate content in acidic etching baths (pdf, Metrohm Information 2/2006)
• Determining the phosphate content in liquid fertilizers (pdf, Metrohm Information 2/2006)
• Determining the sulfate and total acid content of a nitrating
  solution (pdf, Metrohm Information 2/2006)
