Study Notes

Chemical Reactions and Salt Preparation

  • Several methods exist for preparing salts
  • Acid reacting with a metal:
    • Example: 2HCl (aq) + Zn(s) → ZnCl₂(s) + H₂ (g)
  • Acid reacting with a metal oxide:
    • Example: H₂SO₄(aq) + CaO(s) → CaSO₄(s) + H₂O(l)
  • Acid reacting with a base:
    • Example: HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l)
  • Acid reacting with a salt:
    • Example: H₂SO₄(aq) + 2NaCl(aq) → Na₂SO₄(aq) + 2HCl(aq)
  • Salt reacting with a base:
    • Example: CuSO₄(aq) + 2NaOH(aq) → Cu(OH)₂(s) + Na₂SO₄(aq)
  • Salt reacting with a metal:
    • Example: CuSO₄(aq) + Fe(s) → FeSO₄(aq) + Cu(s)
  • Salt reacting with another salt:
    • Example: NaCl(aq) + AgNO₃(aq) → NaNO₃(aq) + AgCl(s)
