electrolyze
C2Technical/Scientific
Definition
Meaning
To decompose a chemical substance by passing an electric current through it.
To subject a substance to electrolysis, causing it to split into its constituent elements or compounds.
Linguistics
Semantic Notes
Mostly used as a transitive verb. The process involves electrodes (anode and cathode) and an electrolyte. The noun form is 'electrolysis'. Often used in chemistry, metallurgy, and industrial processes.
Dialectal Variation
British vs American Usage
Differences
British English commonly uses 'electrolyse' (with an 's'). American English uses 'electrolyze' (with a 'z').
Connotations
Identical in both varieties; purely technical.
Frequency
Equally rare in general language but standard in technical contexts in both regions.

Learning
Memory Aids
Mnemonic
Think of ELECTRICITY causing a substance to LYZE (like 'analyze' or 'paralyze') — it breaks it apart.
Conceptual Metaphor
ELECTRICITY AS A SCALPEL (it cuts chemical bonds).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'электризовать' (to electrify/charge with static). The correct equivalent is 'подвергать электролизу'.
Common Mistakes
- Confusing 'electrolyze' (verb, process) with 'electrify' (to charge with electricity).
- Using it intransitively (e.g., 'The solution electrolyzes' is less common; prefer 'The solution undergoes electrolysis').

FAQ
Frequently Asked Questions
No. 'Electrolyze' is a chemical process. 'Electrocute' means to injure or kill with electricity.
The noun form is 'electrolysis'.
No, only liquids that contain ions (electrolytes) can undergo electrolysis. Pure water, for example, is a very poor conductor and is not easily electrolyzed without an added electrolyte.
UK English uses 'electrolyse', while US English uses 'electrolyze'. The pronunciation is essentially the same.
