This is the pronunciation key for IPA transcriptions of Polish on Wikipedia. It provides a set of symbols to represent the pronunciation of Polish in Wikipedia articles, and example words that illustrate the sounds that correspond to them.
Vanadium(V) oxide serves the crucial purpose of catalysing the mildly exothermic oxidation of sulfur dioxide to sulfur trioxide by air in the contact process: 2 SO 2 + O 2 ⇌ 2 SO 3 The discovery of this simple reaction, for which V 2 O 5 is the most effective catalyst, allowed sulfuric acid to become the cheap commodity chemical it is today.
The tongue shape of the postalveolar sounds is similar to the shape postalveolar approximant (one of the realizations of the English /r/ phoneme, see also Pronunciation of English /r/). The alveolo-palatals are pronounced with the body of the tongue raised to the hard palate but a greater area of the front of the tongue is raised close to the ...
Vanadium oxide mainly refers to: Vanadium(II) oxide (vanadium monoxide), VO; Vanadium(III) oxide (vanadium sesquioxide or trioxide), V 2 O 3; Vanadium(IV) oxide (vanadium dioxide), VO 2; Vanadium(V) oxide (vanadium pentoxide), V 2 O 5; Various other distinct phases include: Phases with the general formula V n O 2n+1 exist between V 2 O 5 and VO 2.
For English words, transcriptions based on English spelling ("pronunciation respellings") such as prə-NUN-see-AY-shən (using {}) may be used, but only in addition to the IPA ({}). Whatever system is used, any transcription should link to an explanation of its symbols, since such symbols are not universally understood.
Vanadium(II) oxide is the inorganic compound with the idealized formula VO. It is one of the several binary vanadium oxides. It adopts a distorted NaCl structure and contains weak V−V metal to metal bonds. VO is a semiconductor owing to delocalisation of electrons in the t 2g orbitals.

In Polish orthography, sz represents a voiceless retroflex fricative /ʂ/.It usually corresponds to š or ш in other Slavic languages. It is usually approximated by English speakers with the "sh" sound (and conversely, Polish speakers typically approximate the English digraph sh with the "sz" sound), although the two sounds are not completely identical.
