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 analysis of Cu from brass solution is considered as an iodometric titration?
Because the iodine is liberated, hence it is called as iodometric titration.
What is hypo solution used in chemistry for iodometric titration?
hypo solution used in iodometric titration is sodiumthiosulphate. Its N\10 normality of Na2S2O3.
Why add excess KI in iodometric titration?
excess KI
Is iodometric titration and redox titration is same?
No, they are not the same, but 1 is part of 2.Iodometric titration is just one of the (larger) group (or class) of oxidimetric titrations, which in turn is part of the much (larger) group (or class) of volumetric analysis method.

What is meant by drift in a KF titration?
drift means gram eqv. of water removed by K.F. in Iodometric titration
What is iodometry and iodimetry titration?
Iodometric titration is synonymous with redox titration method. Iodine is a universal laboratory reagent because it reacts directly with an array of organic and inorganic substances. Since iodometric titration is a form of redox or oxidation-reduction reaction, it can accurately measure the amount of oxidizing or reducing agents in a chemical reaction. Also, it can be reversed to either direction in an iodine/iodide reaction.
What is idometry?
Iodometry, also known as iodometric titration, is a method of volumetric chemical analysis, a redox titration where the appearance or disappearance of elementary iodine indicates the end point.
Why thiosulphate titration is called as redox titration?
A thiosulfate titration is mostly carried out to determine the amount of iodine present in the solution. In these reactions, thiosulfate ion acts as the reducing agent. This types titrations are often called as 'iodometric titrations'.
What is the function of starch solution in the redox titration?
It is used as indicator for the endpoint of a Iodometric (redox) titration: it gives a bluish grey to black color with very minute excess of Iodine-iodide ions (I3-)
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 the function of NH4CNS in estimation of the amount of copper present in a supplied solution by iodometric method?
The end-point of the titration is more sharper if NH4CNS exist in the solution;
