6 Important Difference between Iodometry and Iodimetry with Table

April 2022 ยท 2 minute read

What is the difference between iodometry and iodimetry?

Iodometry and iodimetry tend to related to each other due to the presence of iodine. These terms are commonly used in titration by the use of iodine to test the concentration of an analyte under investigation.

The core difference between iodometry and iodimetry is iodometry is an indirect titration method while iodimetry is a direct titration method.

What Is Iodometry?

Iodometry is an indirect titration method where the iodine used was produced prior to redox titration is quantified through a separate titration.

The iodometric titration experiment help to determine the concentration of analyte that is used to produce iodine.

The experiment is quite popular in the situation where the amount of oxidizing agents in a water body needs to be quantified.

What Is Iodimetry?

Iodimetry is a direct titration method where the analyte under investigation is supposed to be a reducing agent. The titration with standard iodine solution can only happen with a good indicator.

The endpoint of the reaction can be obtained from information on the stoichiometry equations and other necessary relationships such as reducing agents and iodine solution which act as an oxidizing agent.

Core Difference between Iodimetry and Iodometry

  • Iodometry is a titration where the iodine produced in the previous redox reaction is titrated with a reducing agent whereas iodimetry is a titration where iodine solution is directly titrated with the reducing agent
  • Iodometry is an indirect method of analysis whereas iodimetry is a direct method of analysis
  • Iodometry entails two redox reaction whereas iodimetry entails a single redox reaction
  • Iodine in iodometry get oxidized first then reduced by the reducing agent whereas in iodimetry the iodine get reduced immediately
  • Iodometry is commonly seen in a lot of experiments while iodimetry is less commonly seen in experiments
  • Iodometry is used to quantify oxidizing agents while iodimetry is used to quantify reducing agents

    Summary

    The core difference between iodimetry and iodometry is that iodimetry involves direct titration while iodometry involves an indirect titration method.
