Reaction between thiosulfate and iodine

WebA redox reaction occurs between iodine and thiosulfate ions: 2S2O32– (aq) + I2 (aq) → 2I–(aq) + S4O62– (aq) The light brown/yellow colour of the iodine turns paler as it is … Websimultaneously forming iodine, and if the iodine is subsequently titrated with thiosulfate, the technique is iodometry. Iodometry is an example of an indirect determination since a product of a preliminary reaction is titrated. The use of iodine as a titrant suffers from two major disadvantages. First, iodine is not

WebSep 24, 2024 · By the addition of iodine, the predominant reaction occurs between iodine and thiosulfate. As iodine concentration is increased, free thiosulfate is decreased due to the interaction with iodine, results in lower aggregation values. WebThiosulfate ions can react with iodine molecules (I 2 ), one of the products of the previous reaction, as shown in equation 22-2. The reaction between S 2 O 3 2-and I 2 is extremely fast; hence, the I 2 produced in reaction 22-2 is immediately consumed. When S 2 O 3 2-is present in the solution, I 2 cannot exist concurrently. But once S 2 O
