Study Notes
Reaction with Acids
- Metals react with dilute acids like hydrochloric acid and sulphuric acid to form corresponding salts and liberate hydrogen.
- Vigorousness of the reaction decreases as we move down the reactivity series.
- Sodium and potassium react violently with acids.
- Magnesium and aluminium react quite vigorously with acids.
- Iron and zinc show moderate reaction with acids.
- Tin and lead react slowly with acids.
- Silver and gold do not react with acids at all.
Reaction Examples
- 2Na (Sodium) + 2HCl (Hydrochloric acid) → 2NaCl (Sodium chloride) + H₂ (Hydrogen)
- Mg (Magnesium) + 2HCl (Hydrochloric acid) → MgCl (Magnesium chloride) + H₂ (Hydrogen)
- Zn (Zinc) + 2HCl (Hydrochloric acid) → ZnCl (Zinc chloride) + H₂ (Hydrogen)
Special Cases
- Some metals react only with concentrated acids.
