Gold and Platinum will react The #H^+# ion produced by #HCl# is not a strong oxidizing agent, and does not react with metals like Ag or Au. In general, acids react with metals to give salt and release hydrogen gas. This means that they will not displace the hydrogen ions in acids, and thus will not dissolve in acids. What happens when metals react with acids. However, nitrate ions are easily reduced to nitrogen monoxide and nitrogen dioxide. 4. If there is a mercury spill, we must leave the area immediately and inform our parents or teachers. It is because Aluminium is a reactive metal It reacts with acids contained in food to form toxic salts Reaction of less reactive metals with Acids Less reactive metals do not react with dilute acids The reactivity series of metals can be used to predict which metals will react with acids. As discussed previously, metals that are more active than acids can undergo a single displacement reaction.For example, zinc metal reacts with hydrochloric acid, producing zinc chloride and hydrogen gas. Nitric acid is one such example, and it will dissolve copper, silver, mercury, and others. 4.7.3.1 Reactions of acids. The elemental metal is oxidized to metal cations in the process. 2.
