Definition
Meaning and Definition
An inorganic compound with the formula LiOH, consisting of lithium ions and hydroxide ions, forming a white hygroscopic solid.
A strong base used in industrial applications such as the production of lithium grease, as a CO2 scrubber in confined environments like spacecraft and submarines, and as a precursor in the manufacture of other lithium compounds.
Dialectal Variation
British vs American Usage
Differences
No significant lexical or spelling differences. Both variants use the same term identically. Pronunciation differences follow general rules for 'lithium' and 'hydroxide'.
Connotations
None beyond its technical meaning. No cultural or regional connotations are attached to the compound itself.
Frequency
Equally rare in general discourse in both regions. Frequency is tied entirely to specific scientific, engineering, or industrial contexts.

Common Mistakes When Using “lithium hydroxide”
- Mispronouncing 'hydroxide' with stress on the first syllable (/ˈhaɪ.drɒk.saɪd/ is incorrect).
- Treating it as a plural noun ('lithium hydroxides' is rare; it's typically a mass noun).
- Confusing it with 'lithium carbonate' (Li2CO3), which has different applications.
FAQ
Frequently Asked Questions
Yes, it is corrosive. Solid LiOH and its concentrated solutions can cause severe burns to skin and eyes. It must be handled with appropriate personal protective equipment (PPE).
It is the most common commercial form of lithium hydroxide, with one water molecule per LiOH formula unit (LiOH·H2O). It is less hygroscopic than the anhydrous form.
It is a key precursor in the production of lithium-ion battery cathodes, particularly for materials like lithium cobalt oxide (LCO) and lithium iron phosphate (LFP).
It reacts chemically with carbon dioxide to form lithium carbonate and water: 2 LiOH + CO2 → Li2CO3 + H2O. This irreversible reaction removes CO2 from the air.
An inorganic compound with the formula LiOH, consisting of lithium ions and hydroxide ions, forming a white hygroscopic solid.
Lithium hydroxide is usually technical, scientific in register.
Lithium hydroxide: in British English it is pronounced /ˈlɪθ.i.əm haɪˈdrɒk.saɪd/, and in American English it is pronounced /ˈlɪθ.i.əm haɪˈdrɑːk.saɪd/. Tap the audio buttons above to hear it.

Mnemonic
Think of a 'lithium' battery needing a 'hydroxide' clean-up crew to scrub out acidic CO2, linking its two main uses.
Conceptual Metaphor
A SPONGE FOR ACID (as in 'lithium hydroxide scrubs carbon dioxide from the air').
