Question

I2(aq) + 2 SO3 (aq)+2I- (aq) +S4O62-
balance the equation​

Answer 1

2S2O3^2- +I2=S4O6^2- +2I-

Oxidation half :

2S2O3^2- = S4O6^2- +2e-

Reduction half :

I2+2e-=2I-

The above redox reaction is used in volumetric estimations of a number of substances. We have direct titration of iodine with hypo known as iodimetry and then iodine liberated in a particular reaction and then titrated with hypo is called iodometry. Estimation ofCuSO4 is iodometry.
