Iodine titration can be iodemotric or iodimetric depending on using iodine directly or indirectly is an oxidising agent in the redox titration. a. Iodimetric titration in which a standard iodine solution is used as an oxidant and iodine is directly or indirectly titrated against a reducing agent. For example. 2CuSO_(4)+4KJtoCu_(2)I_(2)+2K_(2)SO_(4)+I_(2) b. Iodimetric procedures are used for the datermination of strength of reducing agent such as thiosulphates, sulphites, arsenties adn stanous chloride etc. by titrating them against standard solution of iodine in a burette. 2Na_(2)SO_(3)to2 NaI +Na_(2)S_(4)O_(6) Starch is used as indicator near the end point whilch form blue colour complex with I_(3)^(-) .

The heating process for the extraction of elements are quite old but highly acceptable method for the extraction of elements. Become in this process the elements produced is in the highly pure state. Mostly As, Sb,Ni, Zr,B etc are prepared by this principle 4 mumber of metal sulphides which may be reated first in air to partially convert them to the aride, and then further roasted in the absence of air, wing self reduction. The H_(2) (g) is not widely used as a reducing agent because
