Reaction of zinc with dilute sulphuric acid:Zinc sulphate and hydrogen gas are formed when zinc reacts with dilute sulphuric acid. Beryllium has a strong oxide layer (rather like the more familiar aluminium) which slows reactions down until it has been removed. The rate of reaction depends on the 1. concentration of the acid – if the acid is too dilute the reaction is very slow. They are unable to displace the hydrogen when an anion is not metal. A metal will liberate hydrogen by its reaction with dil. Aqueous solution of metal oxides turns red litmus blue. When most metals react with most acids, what they are actually doing is reducing hydrogen ions to hydrogen gas by adding electrons to the hydrogen ions. 1)Magnesium metal react with dilute hydrochloric acid to form magnesium chloride and hydrogen gas. Reaction I. Most metals will react with dilute acids to give a salt and hydrogen gas. Metals react with. A chemical reaction between an acid and a metal can be confirmed by conducting a hydrogen pop test. Dilute acids react with relatively reactive metals such as magnesium, aluminium, zinc and iron. Copper, silver and mercury will not react with dilute acid. Nitric acid is a very strong oxidizing agent. These are more complicated. The problem with nitric acid, HNO 3, is that a nitrate ion, NO 3-, is a much stronger oxidising agent than a hydrogen ion. When a metal reacts with a dilute acid, a salt and hydrogen are formed. Hydrogen gas is formed, along with colorless solutions of beryllium or magnesium sulfate. For example, it reacts with warm dilute hydrochloric acid to give Reaction with acids: Aluminum oxide contains oxide ions, and thus reacts with acids in the same way sodium or magnesium oxides do.
