6
Q
A
Electrons flow from metal higher in electrochemical series to one lower down
7
Q
A
A
Metals including Al and above can only be obtained from their ores by Electrolysis
8
Q
A
E
Hydrogen. Metals are oxidised (lose their electrons) to the H+ (aq) ions allowing them to form a covalent bond and come off as hydrogen gas
9
Q
A
A&D
Ionic solutions will conduct as the ions are free to move.
