Question

In iodometric and iodimetric titration? What is the reason for adding starch solution as indicator at the end of this titration

Answer 1

Answer:

In an iodometric titration, a starch solution is used as an indicator since it can absorb the I2 that is released. This absorption will cause the solution to change its colour from deep blue to light yellow when titrated with standardised thiosulfate solution. This indicates the end point of the titration.
