- Electrolytic Process
- CONDITIONS
- Ions that are free to move
- Posotive and negetive electode
- Power Supply
- Electolyte: Ionic substunce that conducts the electricity when Aqueus/Molten
- WHAT IS IT?
- When ionic substances are broken down when a current is pass through
- O.I.L.R.I.G.
- ANIONS & CATIONS
- ANIONS
- Negatively charged so they are attracted to the ANODE
- At the anode they LOOSE Electrons (Oxidisation)
- CATIONS
- Posotively charged ions so they are attracted to the CATHODE and Gain electrons (Reduction)
- ANIONS
- Electrolysis of COPPER CHLORIDE
- CATHODE
- Copper Ions
- Gain 2 Electrons
- Half Equation:
- Forms Copper wiich appears brown (Solid) at the electrode
- ANODE
- Chloride ions
- Loose an electron
- Chlorine atoms join up (Cl2)
- Gas
- Half Equation:
- CATHODE
- LEAD BROMIDE
- CATHODE
- Lead is forced to gain 2 electrons
- Forms a liquid
- Half equation
- ANODE
- Bromine ions loose an electron
- Form diatomic bromine molecules
- Brown gas at electrode
- Half Equation
- CATHODE
- CONDITIONS
