What does the negative sign in the expression E_(Zn^(2+)|Zn)^(Theta)=-0.76V mean ? |
| Answer» Solution :* As the NEGATIVE value of REDUCTION POTENTIAL of metal is more, metal become more reactive. Such metal get easily oxidized with respect to `H_(2)`. And such metal produced `H_(2)` gas on reaction with acid. Metal will be soluble in acid. Here, `H^(+)` is reduced and metal Zn get oxidized. They will form anode of Zn and cathode of `H_(2)` in galvanic cell. | |
