Aqueous Electrolysis

• write magnesium chloride as an ionic compound:

  Mg2 CI- MgCI2
• write sodium bromide as an ionic compound:


  Na+ Br- NaBr
• write aluminium oxide as an ionic compound:


  AI3+ O2- AI2O3
• What is ‘aqueous’?

  A substance dissolved in water to form a solution.
• During aqueous electrolysis what are always pesent?

  Hydrogen ions (H+) H2O -> H+ + OH-

  Hydroxide ions (OH-)
• H+ hydrogen ions are attracted to the cahtode.
• OH- hydroxide ions are attracted to the anode.
