Relevance. and hydrogen are formed. has more dissolved oxygen,than the normal acid.This oxygen reacts with aluminium forming oxide layer over the surface,and causes slow reaction of Al with acid. magnesium hydroxide forms. Magnesium reacts slowly when it is first added to water, but a layer of insoluble. When a metal reacts with a dilute acid, a salt. Copper is below hydrogen in the reactivity series of metals, so it is unable to displace hydrogen from sulphuric acid. Reactions of metals with acids. The reaction is similar to the reaction with water, forming the metal salt (either sulfate or chloride) plus H 2(g).. For example. Answer Save. Sulphuric acid to liberate sulphur dioxide gas as per the equation — Hope it helped ! The Reaction of Metals with Dilute Acid.. Potassium, sodium, lithium and calcium all react violently with dilute sulfuric acid and dilute hydrochloric acid. Dilute acids react with relatively reactive metals such as magnesium, aluminium, zinc and iron. Metals usually displace hydrogen from dilute acids. It however reacts with conc. What explanation can you offer for the slow reaction of aluminium. Reaction of metals with dilute acids. Why does aluminum typically react slowly with dilute acids even thought Mg and Zn react rapidly? 4 Answers. Aluminium metal will react with dilute hydrochloric acid to produce aqueous aluminium chloride, "AlCl"_3, and hydrogen gas, "H"_2. Pure Aluminum reacts with dilute Sulfuric acid to produce Aluminum Sulfate and release Hydrogen gas Al + H2SO4 -> Al2(SO4)3 + H2 Dilute acids have water concentration more than normal/strong,the acid containing water . ! The Reactivity Series. Explain why aluminium reacts slowly with dilute hydrochloric acid? The products of the reaction are a salt plus hydrogen gas. The standard electrode potential of aluminium and magnesium suggests that aluminium and magnesium should react easily with dilute hydrochloric acid. Hydrogen gas is being produced. It is dangerous to put these metals into an acid. Less reactive metal(Cu,Au,Ag) do not displace hydrogen from dilute acid.
