1. What products will be formed when Copper Chloride is electrolysed? Write down the ones you think are right on your mini white board. Be prepared to justify your answer and argue your point! a)Copper b)Chlorine c)Chloride d)Hydrogen e)Oxygen

2. What products might be formed when Potassium Hydroxide solution is electrolysed? Write down the ones you think are right on your mini white board. Be prepared to justify your answer and argue your point! a)Oxygen b)Hydroxide ions and Potassium c)Potassium and Hydrogen d)Hydrogen e)Hydrogen and Oxygen What might your answer depend on?

3. How can we explain the products of electrolysis of Copper Sulfate? I think this is irrelevant I think this is relevant I know this is irrelevant I know this is relevant Ions are attracted to the different electrodes Copper Sulfate is soluble Water can be separated into ions Some ions are more strongly attracted to electrodes than others More reactive ions are preferentially formed at electrodes Hydrogen is one of the products Electricity passes through the solution Ions are charged atoms
