| Potential difference Different pairs of metalls give different potential difference.Metal atoms in the electrode lose electrons to produce ions.
The more easily a metal loses electron, the more negative is. |
Electrochemicall
series The series , produced by the behaviour of
different pairs of metalls in voltaic cells is called
electrochemical series.This series include all metals.Here are a few of them: Ca..Mg..Al Zn.. Fe.. Pb.. Cu.. Hg.. Ag.. The closer the metals are in the series the smaller the potential difference. |
