WebWhat is Iodometric titration. Iodometric titration, also known as Iodometry, is a type of indirect titration. The analyte solution is an oxidizing agent in Iodometric titrations. It is reacted with an excess amount of potassium iodide (KI). The oxidizing agent oxidizes iodide (I–) ions into iodine (I2). Web25% are added. For alkaline samples, more H 2 SO 4 may be needed. After dissolving the sample, 1-1.5 g of KI are added. The solution turns reddish-brown. Then it is titrated with Sodium thiosulfate 0.1 mol/L to an Equivalence point (EQ). The amount of sample should be adjusted so that the consumption at EQ is about 20 – 90% of the burette volume.
