Some facts#

  • Galwanic series (voltage, electrochemical) sets up elements according to their standard potential.
  • The standard potential is measured relative to the hydrogen electrode. The potential of this electrode is assumed to be equal to zero.
  • The position of the element in the galvanic series corresponds to its chemical activity.
  • Metal located lower in the galvanic series (i.e. metal with a lower normal potential) can displace atoms of other metals from their salts.
  • Metals whose standard potential is less than the potential of a hydrogen electrode can displace hydrogen atoms from water. Such metals are usually called active metals or non-noble metals.
    ⓘ Example: Sodium displaces hydrogen atoms from water to form a sodium base:
    2Na+2H2O2NaOH+H22Na + 2H_2O \rightarrow 2NaOH + H_2\uparrow
  • The lower potential of the element, the stronger reducer it is.
  • The higher potential of the element, the stronger oxidiser it is.
