Iodite

<h2 id="iodite-anion">Iodite anion</h2>
<p>Iodites (including <a href="/facts/Iodous_acid/1LBRGCfm">iodous acid</a>) are highly unstable and have been observed<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a> but never isolated. They will rapidly disproportionate to molecular <a href="/facts/Iodine/JlfMecMf">iodine</a> and <a href="/facts/Iodate/n60p0YSa">iodates</a>.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> However, they have been detected as intermediates in the conversion between <a href="/facts/Iodide/JyVRGWMX">iodide</a> and <a href="/facts/Iodate/n60p0YSa">iodate</a>.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a><a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a>
