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 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.

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.
