Factors that affect an electrolysis reaction

Describe factors that affect an electrolysis reaction
  • effect of concentration
  • nature of electrolyte
  • nature of electrodes


Change:Effect on Reaction:
Increased currentIncreased rate of electrolysis
Increased voltageIncreased current, and therefore increased rate of electrolysis
Increased concentration of ions in electrolyteIncreased current, and therefore increased rate of electrolysis
Increased surface area of electrodesIncreased current, and therefore increased rate of electrolysis
Decreased distance between electrodesIncreased current, and therefore increased rate of electrolysis
Inert electrode to active electrodeElectrode can oxidise
