<p>[QUOTE=&quot;NSP, post: 2533264, member: 74849&quot;]Upon looking at a reduction potential table, it seems that copper could react with nitric acid and perchloric acid. Under standard conditions, copper won&#039;t oxidize (and thus dissolve) itself to reduce H+ ions from an acid into hydrogen gas. The nitrate ion in nitric acid and the perchlorate ion in perchloric acid can react in ways that theoretically could be enough to oxidize and dissolve copper. </p><p><br /></p><p>[Disclaimer: this doesn&#039;t come from any personal experience other than reading a reduction potential table, so I&#039;d happily defer to any chemist&#039;s experiences with the subject]</p><p><br /></p><p>Really cool experiment![/QUOTE]</p><p><br /></p>
