Products when metals react with acids

Salt and hydrogen gas

General equation: Metal + Acid →

Salt + Hydrogen

Products: Mg+2HClMg + 2HCl →

MgCl2+H2MgCl_{2} + H_{2}

Products: Zn+H2SO4Zn + H_{2}SO_{4} →

ZnSO4+H2ZnSO_{4} + H_{2}

Reaction speed of highly reactive metals with acids

Quick and often violent, releasing H2H_{2} gas and heat

Examples of highly reactive metals (with acids)

Sodium and magnesium

Reaction of less reactive metals with dilute acids

Much slower or not at all

Examples of less reactive metals (with acids)

Copper and silver

What helps predict metal-acid reactions

Reactivity Series

Reactivity Series position & reaction with acids

Higher = more readily, lower = less readily

Industrial use of metal-acid reactions

Production of hydrogen gas

Metal-acid knowledge for corrosion prevention

Selecting materials that resist acidic environments

Use of acids in metal extraction

Dissolving metals from their ores
