Standard Operating Procedure
• Use glass, preferably Pyrex, containers. Aqua regia will melt some plastics and corrode most metals. • Dissolving metals in aqua regia releases toxic gases, so always work with aqua regia in a fume hood. • Aqua regia solution is very energetic and potentially explosive. It is very likely to become hot (up to 100°C). Handle with care.
