Metal + Acid → ?

Salt + Hydrogen

Products of metal-acid reactions

Salt and hydrogen gas

Salt from Mg + HCl

Magnesium chloride (MgCl2MgCl_2)

Salt from Zn + H2SO4H_2SO_4

Zinc sulfate (ZnSO4ZnSO_4)

Equation: Mg + HCl

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

Equation: Zn + H2SO4H_2SO_4

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

How highly reactive metals react with acids

Quickly/violently, release H2H_2 & heat

How less reactive metals react with acids

Slowly or not at all with dilute acids

Reactivity Series & acid reactions

Higher metals react more readily

Applications of metal-acid reactions

H2H_2 production, corrosion prevention, metal extraction
