Aim: Standardization of Sodium Thiosulphate using Iodometric Titration

Standardization of sodium thiosulphate solution

Method: Standardization of Sodium Thiosulphate using Iodometric Titration

Iodometric titration.

Objectives: Standardization of Sodium Thiosulphate using Iodometric Titration

  • <p>Standardization of a prepared solution of sodium thiosulphate.

  • Understanding the difference between iodometry and iodimetry.

  • Understanding the concept of iodometry.

  • Understanding the concept of redox reactions.</p>

Theory| Iodometric Titration Experiment using Sodium Thiosulphate

Iodometric titration: The titration in which the sample has oxidizing properties. Upon adding potassium iodide, free iodine is liberated equivalent to the sample. The liberated iodine can be easily determined against a standard reducing agent.
 
Iodimetric titration: The titration in which the sample has reducing properties and thus can be determined directly against Iodine.

Principle: Standardization of Sodium Thiosulphate Solution

Sodium thiosulphate is a reducing agent which can be standardized against iodine (oxidizing agent ) by iodometric titration.
