Mention the principle in iodometry. – InterviewSolution

1.	Mention the principle in iodometry.
Answer» Solution :Even mild oxidants can oxidise iodide to IODINE. The iodine LIBERATED is titrated using sodium thiosulphate in volumetry, using STARCH indicator. Starch - iodine is blue and at the END point blue colour disappears. `2Na_(2)S_(2)O_(3)+I_(2)rarr2NaI+Na_(2)S_(4)O_(6)`
