Products when metal reacts with acid

Salt and hydrogen gas

General equation: Metal + Acid →\rightarrow

Salt + Hydrogen

Factor determining metal-acid reaction speed

Reactivity of the metal

Products: Mg + hydrochloric acid

Magnesium chloride + hydrogen gas

Balanced equation: Mg + HCl

Mg+2HCl→MgCl2+H2Mg + 2HCl \rightarrow MgCl_2 + H_2

Products: Zn + sulfuric acid

Zinc sulfate + hydrogen gas

Balanced equation: Zn + H2SO4H_2SO_4

Zn+H2SO4→ZnSO4+H2Zn + H_2SO_4 \rightarrow ZnSO_4 + H_2

How highly reactive metals (Mg, Na) react with acids

Quickly and violently, releasing lots of H2H_2 and heat

How less reactive metals (Cu, Ag) react with acids

Very slowly or not at all with dilute acids

Tool to predict metal-acid reactions

Reactivity Series

Industrial use of metal-acid reactions

Production of hydrogen gas

Metal-acid knowledge use in corrosion prevention

Selecting materials resistant to acidic environments
