What is the total number of moles of electrons transferred during the disproportionation of 3 moles β Redox Reactions and Volumetric Analysis Chemistry Question
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?
Answer: 5
π‘ Solution & Explanation
The balanced reaction is: $3Cl_2 + 6OH^- \rightarrow 5Cl^- + ClO_3^- + 3H_2O$. 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.
