SUMMARY
The discussion centers on the stoichiometry of two chemical reactions involving chlorine and thiosulfate ions. Reaction 1, Cl2(g) + 2I–(aq) --> I2(aq) + 2Cl–(aq), and Reaction 2, 2S2O3^(2-)(aq) + I2(aq) --> S4O6(2-)(aq) + 2I–(aq), are analyzed for their stoichiometric relationships. The confusion arises regarding the relationship between the moles of I2 and S2O3^(2-), specifically why n(I2)(reaction 2) does not equal 2n(S2O3^(2-))(reaction 2). The resolution involves confirming the balance of atoms and electrons, as referenced in the Wikipedia article on thiosulfate.
