I Enjoy it, but I've done the paper, (well, the bits we've been taught) and the MyMaths sucks for it! So I don't know how to properly revise for it.

So the less reactive one discharges at the electrode, right?

Chlorine gas (cl2) and Hydrogen gas (h2) are produced.

The sodium and hydroxide are left ofter, which join to form sodium hydroxide (NaOh).

You also need to know the uses of them.

Chlorine is used to make bleach, clean water and plastics. Hydrogen can be used to make margarine and the Sodium Hydroxide can be used to make cleaning products such as soap.
