What is iodometric titration?
In this titration iodine is liberated ....Added:... from (excess of) iodide by an oxidant. The Iodine is then titrated with thio (di-sodium thio-sulfate) and starch as indicator added just before the expected equivalence point.
Why starch is added in iodometric titration?
The color formed by reaction between starch and iodine is much more intense than the color of iodine itself, so that the end point can be determined more sensitively with than without starch.
Is the indicator generally added to the titrant or the analyte in a titration?
Analyte is the indicator that is generally added in titration.
Why starch is used as indicator in iodometric titration?
Starch is not used in order to do this. This is because starch is able to form a complex along with the iodine and this is the indicator.
What is a back titration?
A back titration is a form of titraiton in which an excess of standard reagent is added and then the reverse of the titration is carried out.

What is Over titration?
Over titration occurs when an excess of one solution, known as a titrant, is added to another solution. Titration is done to know the amount of solution to be added to reach neutralization.
Why you use starch as indicator in iodometric titration?
Because starch forms a dark blue colored soluble product with free iodine, so that the appearance of color in the solution from this reaction effectively shows when all the substances in the solution that react more strongly with iodine than does starch have been consumed and the titration is finished.
What is the usage of KCNS in a iodometric titration?
Some of the metal ion that is estimated (especially Cu2+) may get trapped within starch indicator. When KCNS is added, copper thiocyanate or Cu(CNS)2 complex is formed which then reacts with the KI added, giving correct results.
Why is nitrobenzene added to titration mixture?
to standardise the solution
