Consolidate for electrolysis
| Question | Answer |
|---|---|
| What does electrolysis mean? | Splitting up ionic compounds using electricity |
| Why does the electrolyte need to be molten? | So the ions are free to move |
| What charge does the anode have? | Positive |
| What charge does the cathode have? | Negative |
| What is the name for ions that are attracted to the anode? | Anion |
| What is the name for ions that are attracted to the cathode? | Cation |
| What charge does an anion have? | Negative |
| What charge does a cation have? | Positive |
| Which electrode do metal ions go to? | Cathode |
| Which electrode do non-metal ions go to? | Anode |
| What happens to the metal ion when it gets to the cathode? | gains electrons |
| What happens to the non metal ion when it gets to the anode? | loses electrons |
| What do we call it when ions gain electrons? | Reduction |
| What do we call it when ions lose electrons? | Oxidation |
| What is the acronym we can use to remember the charge of electrodes? | P.A.N.I.C. |
| What is the acronym we can use to remember oxidation and reduction? | O.I.L.R.I.G. |
