Question

What is the total number of moles of electrons transferred during the disproportionation of 3 moles of $Cl_2$ in a hot, concentrated $NaOH$ solution according to the balanced chemical equation?

Prashant Kotian · Accepted Answer

Correct answer: 5. The balanced reaction is: . Here, 5 atoms of Chlorine are reduced from 0 to -1 (gaining a total of 5 moles of electrons). 1 atom of Chlorine is oxidized from 0 to +5 (losing a total of 5 moles of electrons). Thus, the total electron transfer is 5 moles.
