Parshotam Posted July 25, 2013 Share Posted July 25, 2013 A mixture containg 1 part by volume of HNO3 ( conc ) and 3 parts by volume of HCl is called agua regia which means royal water. It can dissolve gold and other noble metals due to liberation of chlorine. It forms Hydroauric chloride. Link to comment Share on other sites More sharing options...
