Generally the end point for the process is signaled by the complete
disappearance of the iodine . The equivalent weight for the iodate is one - fourth
of its formula weight because the final reaction product is iodine in the + 1 state .

The reaction between iodine and thiosulfate is described by the equation
2S2O32 - + Iz = S 062 - + 21 * The production of the tetrathionate ion requires the
loss of two electrons from two thiosulfate ions ; the equivalent weight of
thiosulfate in ...
