<p>[QUOTE=&quot;halfcent1793, post: 3958146, member: 86853&quot;]This is a bit of a matter of definition. If by &quot;metal&quot; you only mean actual metal, that&#039;s one thing, but if by &quot;metal&quot; you also include salts of the metal, which are actually minerals, that&#039;s another thing. To my mind, &quot;metal&quot; refers only to actual metal, not mineral salts.</p><p><br /></p><p>Alkalai does not dissolve gold, silver or copper, but it does dissolve salts of copper and silver that result from exposure to aqueous acids.[/QUOTE]</p><p><br /></p>
