The hydrochloric acid quickly turns a dull grey colour as aluminium chloride … When a piece of aluminium metal is added to dilute hydrochloric acid, the result is two products - an aqueous product and a gaseous product. As with the reactions with water, there are odd cases where the reactivity isn't quite what you would expect. Acids that release a large number of hydrogen ions in water are strong acids. Al is less reactive metal than K,Na etc. and hydrogen are formed. • Potassium and sodium are not used to react with dilute ‘hydrochloric acid or dilute sulphuric acid in the laboratory preparation of hydrogen. Lead does react with hydrochloric acid but it is extremely slow only producing tiny surface bubbles this would be good as a protective coating but its poisonous. Potassium, sodium and lithium. The chemical equation is written below: Mg + 2HCl --> MgCl2 + H2. The standard electrode potential of aluminium and magnesium suggests that aluminium and magnesium should react easily with dilute hydrochloric acid … Once the acid has removed the oxide layer from the aluminium, the reaction speeds up significantly and produces a lot of hydrogen bubbles.
