(b) List two non-electrolysis.

Answer

Answer Details

(a) Two factors that affect the mass of an element deposited during electrolysis (Faraday's laws):

The quantity of electricity passed, i.e. the product of current and time (\(Q = It\)); the mass is directly proportional to it.
The electrochemical equivalent of the element (which depends on its relative atomic mass and valency).

Other acceptable factor: the duration of current flow at a fixed current.

(b) Two non-electrolytes (substances that do not conduct electricity by ionic dissociation):
