Consider the reaction Cr_(2)O_(7)^(2-)+14H^(+)+6e^(-)to2Cr^(3+)+7H_(2)O What is the quantity of electricity in couolombs needed to reduce 1 mole of Cr_(2)O_(7)^(2-)? |
| Answer» Solution :From the given REACTION, 1 mol FO `Cr_(2)O_(7)^(2-)` ions require `6F=6xx96500C=579000C` of ELECTRICITY for reduction to `Cr^(3+)`. | |
