4 syllables: Ox, al, ic Ac, id. Stress on Ox.
AHK-suh-lik-as-id
/ˈɑksəlɪk æsɪd/
Oxalic Acid is pronounced AHK-suh-lik-as-id (/ˈɑksəlɪk æsɪd/). It has four syllables (Ox-al-ic Ac-id), with the stress on "Ox". Oxalic acid is a dicarboxylic acid with the formula (COOH)2 and is produced by several plants. It is a colorless, odorless solid or solution used in cleaning, dyeing, and organic synthesis. In chemistry, it functions as a reducing agent and participates in various reactions, including esterification and decarboxylation.

- Common errors: misplacing stress on Oxalic (saying ox-AL-ic is less common in fast speech); mispronouncing the 'x' as 'z' or 'ks' blend; muffling the final /d/ in 'acid' or switching to a lax vowel in /æ/. - Correction tips: rehearse in syllables: /ɒk/ /ˈsæl/ /ɪk/ then /ˈæs/ /ɪd/. Use slow speed and accurate IPA cues; practice with a pause between words in formal contexts; record and compare to models. Focus on crisp /ks/ in 'ox' and a clean final /d/. Practice with a minimal pair set: /ɒk.sæl.ɪk/ vs /ˈɒk.sæl.ɪk/ to stabilize stress; practice 'acid' as /ˈæs.ɪd/ to avoid schwa reduction in first syllable.
"Oxalic acid is commonly used in wood bleach to remove stains from natural fibers."
"Many plants contain oxalic acid in small amounts, which can contribute to kidney stone formation in susceptible individuals."
"The synthesis involved oxidizing the corresponding alcohol to produce oxalic acid derivatives."
- Pronounce as /ɒkˈsælɪk/ for Oxalic and /ˈæsɪd/ for Acid in US/UK. Stress falls on the second syllable of Oxalic: oɡ-SAL-ik. Lip rounding is moderate, with a clear /ɡ/ release before the /s/. The full phrase: /ɒkˈsælɪk ˈæsɪd/. For US: /ɑˈksalɪk ˈæsɪd/ may appear, but standard is /ɒkˈsælɪk ˈæsɪd/; for UK/ AU, /ɒkˈsælɪk ˈæsɪd/ remains common. Keep the /k/ hard, and ensure the second syllable has a crisp /s/ and short /ɪ/ in 'acid'.
Common errors: treating Oxalic as 'ok-sal-ik' with soft 'x' or wrong stress placement: many say 'OX-a-lik AC-id' instead of 'ox-AL-ik AS-id'. Also mispronouncing 'acid' as 'a-sid' with a schwa in the first vowel, or slipping to 'ox-All-ic'. Correction: say /ˈɒk.sæ.lɪk/ for Oxalic and /ˈæs.ɪd/ for Acid, with primary stress on 'Oxalic's second syllable and on 'Acid' as a single-stress word. Practice by isolating syllables: /ɒk/ /ˈsæl/ /ɪk/ and /ˈæs/ /ɪd/. Voice emphasis should be consistent across the two words.
In US, Oxalic is often pronounced /ˈɒk.sæl.ɪk/ with a more rounded /ɒ/. In UK and AU, you will hear /ɒkˈsælɪk/ with similar vowel quality but quicker r-less or slightly rolled r absence and a crisper /s/. The word 'acid' stays /ˈæs.ɪd/ in all three, though some regional dialects may reduce to /ˈæs.ɪd/ with shorter /ɪ/. The main difference rests on the placement of primary stress in Oxalic: US and UK typically stress the second syllable (ox-AL-ic), while Australian usage can vary slightly but generally mirrors UK/US patterns. IPA references: US /ɒkˈsælɪk ˈæsɪd/, UK /ɒkˈsælɪk ˈæsɪd/, AU /ɒkˈsælɪk ˈæsɪd/.
Two factors make it tricky: the 'ox' cluster and the two-letter 'x' sound in 'oxalic' can cause mispronunciation, plus the stressed second syllable in 'oxalic' may be overlooked in fast speech. The 'ac' in 'acid' can be mispronounced as 'a-sid' or 'uh-sid'. Focus on the crisp /ks/ sequence in 'ox', the clear /l/ followed by /ɪ/ in 'alic', and the voiceless /d/ at the end of 'acid'. Begin slowly, then reduce to natural speed while maintaining syllable boundaries.
Remember the two-word chemical name requires a small pause between Oxalic and Acid in clear speech. Put primary stress on Oxalic's second syllable: o-XL-ic, and keep 'acid' clearly enunciated with a short, crisp /d/. Visualize syllable blocks: /ɒk/ - /ˈsæl/ - /ɪk/ and /ˈæs/ - /ɪd/. Use a mirror or recording to check the lip and tongue positions: you should feel a slight raise of the tongue toward the palate during /s/ and a firm closure for /d/ at the end.

- US: rhoticity is not a major factor here, but ensure a clear /ɒ/ in 'ox' and a light /ɪ/ in 'lic'. Intonation generally flat in lab context; emphasize the second syllable of Oxalic. - UK: more clipped vowels, crisp /æ/ or /ɪ/ in 'alic', maintain non-rhoticity; /ɒ/ in 'ox' remains. - AU: similar to UK; some speakers reduce vowels slightly but keep the /k/ and /s/ sequences clear. Use IPA references: /ˈɒks.əl.ɪk/ or /ˈɒk.sæl.ɪk/ depending on regional syllabification; maintain /æ/ in 'sæl' or /ɪ/ depending on dialect.
Oxalic acid derives from the word oxal, from Medieval Latin oxalis, from Greek oxalis meaning sour. The term likely entered English in the 18th century as chemists formalized naming for acids derived from oxalic organisms and mineral sources. Chemically, it is named ethanedioic acid in systematic nomenclature following the International Union of Pure and Applied Chemistry (IUPAC) rules: 'ethane' refers to two carbon atoms, 'dioic' indicates two carboxyl groups, and the 'acid' suffix denotes proton donors. Historically, oxalic acid was discovered in the 18th century in tartaric crystals from wine production and later isolated from oxalic mineral deposits. The compound became central in organic synthesis as a reducing agent and in cleaning, dyeing, and metal chelation. First known use in English literature traces to early chemical treatises describing reactions and formula derivations for dicarboxylic acids, with its industrial prominence rising in the 19th and 20th centuries as manufacturing and analytical chemistry advanced.
