REACTION OF ACIDS WITH METALS. However, there are some exceptions to this rule, including platinum, gold, silver and copper. These reactions are examples of neutralisation. When an acid combines with metal it forms salt and release hydrogen gas. But unlike the reaction between acids and bases, we do not get water. Metals below hydrogen on the activity series will not react with acids. #ZnCl_2(aq)# = zinc chloride salt dissolved in water Metals below hydrogen on the reactivity series will not react with dilute acids. The magnesium displaces the hydrogen from the acid. For example, zinc metal reacts with hydrochloric … This is an example of a single displacement reaction. One element (the active metal) displaces another in a compound (the acid). General word equation: metal + acid ==> a salt + hydrogen The salt, and its name, depends on the metal and acid used in the reaction and the acid is neutralised in the process. More reactive metals, such as group 1 metals, are too dangerous to mix with acids, due to the explosive reaction. Copper, silver and gold are not active enough to react with these acids. It doesn't matter which metal or which acid is used, if there is a reaction we always get hydrogen gas as well as the salt. Example: Reaction of ethanoic acid and magnesium. Metals like magnesium, zinc and iron are common active metals. metal and acid to make h2 - boxes. Reaction I. metal hydroxide + acid salt + water.
