What does the negative sign in the expression E_(Zn^(2+)//Zn)^(@)=-76 V mean? |
| Answer» Solution :Negative sign for `E_(Zn^(2+)//Zn)^(@)` shows that zinc is more reactive than hydrogen. This MEANS that when zinc electrode is CONNECTED to SHE, Znw will be OXIDIZED to `Zn^(2+)` and `H^(+)` will be reduced to `H_(2)`. | |
