At 25^(@)C, the reduction potential of hydrogen electrode is -0.118V at 1 atm. What is he pH of acid solution used for the construction of the electrode ? |

Answer» Solution :`E=E^(@)+(0.059)/(n) LOG C` (or) `E =E^(@)+(0.059)/(2) log [H^(+)]` `-0.118=0.059 log [H^(+)]` (or) `-log[H^(+)] =2 , pH=2`. |
