Aqueous solution with electrolysis

• What does the aqueous solution contain?

  hydrogen and hydroxide
• what electrode does the hydrogen move too?

  Cathode
• What electrode does the hydroxide move too?

  Anode
• What does the cathode attract?

  positive ions, metals
• The cathode will only discharge one of the ions which will be the least reactive one of the two
• What ion will be discharged at the anode?

  if a halide is present it will be discharged but if it’s not the hydroxide will be
