Explanation:

I hope it helps you

Answer 2

(IV) Electrolysis.

Dissociation :-

It is the breaking up of a compound into simpler constituents that are usually capable of recombining under other conditions

Ionization :-

The process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons,

Filtration :-

The process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium

Electrolyis :-
