9.1 Characteristics of electrochemical series
1. Stronger reducing agents than hydrogen are placed above hydrogen in the series and have negative values of standard reduction potentials.
2. Substances which have positive values of reduction potentials are placed below hydrogen in the series and are weak reducing agents .
3. Substances which are stronger oxidizing agents than $H^+$ ion are placed below hydrogen in the series.
4. Activity of metals decreases from top to bottom.
5. Substances which have tendency to accept electrons readily are active non-metals.
6. Activity of non-metals increases from top to bottom.
7. Metals which have (high negative standard electrode potential) tendency to lose electrons easily and are called active metals.
8. Non-metals on the bottom (have high positive values of standard reduction potential).
