Electrochemical series

Any oxidation reduction reaction 

follow the series




This series arrange the elements according to their oxidizing and reducing ability:

the lower elements can replace the higher one in the solution, for instance:


 As shown in the pic. the zinc when placed in copper sulfate it replaces the copper ions by reducing it  while zinc it self is oxidized   

but, if we put a copper piece in zinc solution no chemical reaction occurs this is due to the zinc has higher reducing agent than copper

as previous also if we immerse an iorn in zinc solution nothing will occur due to zinc is higher reducing agent than copper
