Q

What’s the relationship between reactivity of a metal and redox

A

The more reactive a metal is, the stronger is oxidation strength is. (Hence it is more likely to get oxidised)

Q

Electrolysis products at the cathode and the anode

A

Anode produces Gas (Often Chlorine gas, bromine gas)
Cathode produces liquid solid (Sodium) - NOT SODIUM ION, just liquid sodium
