Pearson Edexcel IAL Chemistry AS 3.1 Evidence for ions
Pearson Edexcel IAL Chemistry AS 3.1 Evidence for ions
Practise using conductivity, electron-density maps and ion-migration observations to justify the presence and movement of ions.
How this is tested
- explain conductivity changes by whether ions are fixed, molten or in aqueous solution
- use electron-density maps or property tables to distinguish ionic from covalent bonding
