electrolysis
Let an agent explain electrolysis by principle, cells, applications and safety, including hydrogen production, without facilitating hazardous misuse.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain electrolysis by principle, cells, applications and safety, including hydrogen production, without facilitating hazardous misuse.
The use of direct electric current to drive a non-spontaneous chemical reaction, such as splitting water into hydrogen and oxygen, extracting aluminium and chlorine, refining copper, and electroplating or electrogalvanising metal surfaces.
What it is for: Chemical production, metal refining, plating and hydrogen production.
It can be explain how an electrolytic cell works; calculate products using Faraday laws; describe industrial and plating uses; handle gases and electrolytes safely.
Distinguishing features
Driven by external current
Oxidation at the anode, reduction at the cathode
Quantified by Faraday laws
Energy-intensive
What it looks like
Cells with electrodes in an electrolyte, bubbles of gas and plating baths.
How it is recognised
Anode and cathode in an electrolyte
Gas bubbles at electrodes
A battery produces current rather than consuming it
