The total number of Faradays required to oxidize the following separately`:` `a. 1 mol of S_(2)O_(3)^(2-)` in acid medium `b. 1 ` Equivalent of `S_(2)O_(3)^(2-)` in acid medium `c. 1 mol of S_(2)O_(3)^(2-)` in basic medium. |

Answer» Correct Answer - 10 `a. S_(2)O_(3)^(2-)rarr (1)/(2)S_(4)O_(6)^(2-)+e^(-)[1F]` `b. S_(2)O_(3)^(2-)+5H_(2)Orarr2HSO_(4)^(c-)+8H^(o+)+8e^(-)` `[1 mol =8F` but `1Eq=1F]` `c. S_(2)O_(3)^(2-) +10overset(c-)(O)Hrarr 2SO_(4)^(2-)+5H_(2)O+8e^(-)` `[1mol=8F]` Total Faradays in `(i),(ii), `and `(iii)=1+1+8=10F` |
